Wider Bearing Support for Thin Sheet & Pre-Drilled Fixtures

Thin sheet & fixtures with existing holes can need more support around the fixing point than a standard drive-pin head provides. ICCONS® | PX Washered With Top Hat Drive Pins combine a PX drive pin, 22 mm metal washer & top-hat component in one pre-assembled fixing for suitable concrete & steel applications.

For builders, installers, fit-out crews, fabricators & maintenance teams, the assembly provides a practical way to fasten compatible thin plastic or metal sheeting & fixtures with pre-existing holes using suitable low-velocity powder-actuated equipment. The metal washer increases the bearing surface around the fixing while the pre-assembled configuration keeps the components together before installation. Compare broader direct-fastening options through Specialty Fasteners & Fixings, review alternative concrete connections through Screws & Anchors or prepare drilled fixing points with  Concrete Cutting & Drilling Tools.

► 22 mm metal washer
► Pre-assembled top-hat configuration

► 3.7 mm pin shank
► 8 mm pin head
► Increased bearing surface at the fixture
► Increased resistance to pull-over
► Suitable for compatible concrete & steel applications
► Designed for ICCONS PX375 & most compatible low-velocity powder-actuated tools
► Useful for suitable thin plastic or metal sheeting
► Suitable for compatible fixtures with existing holes

Why Add a 22 mm Washer to a PX Drive Pin?

The fixture face can be the deciding factor when a standard pin head does not provide enough bearing area for thin material.

A 22 mm metal washer spreads support across a larger area around the fixing point.

That becomes particularly relevant when fastening suitable thin sheet where concentrating the connection around a smaller head could place more localised pressure on the material.

The washered PX assembly is designed to increase bearing surface & improve resistance to pull-over.

This makes the configuration different from choosing a standard PX pin purely by length.

For a broader introduction to selecting fasteners around the material being joined, see the Fastener Guide Bolts Screws Anchors.

Three Pin Lengths Cover the Documented Range

Once the washered top-hat configuration suits the fixture, the next distinction is the drive-pin length.

The range includes:

Part Number

Pin Length

Shank Width

Head Width

Washer

PXWTH20

20 mm

3.7 mm

8 mm

22 mm

PXWTH25

25 mm

3.7 mm

8 mm

22 mm

PXWTH30

30 mm

3.7 mm

8 mm

22 mm

All three configurations use the same documented 3.7 mm shank & 8 mm head while the drive-pin length changes.

Do not choose the longest pin simply because it appears more substantial. Match the exact assembly to the fixture, substrate & applicable installation requirements.

What Does the Top Hat Contribute?

The top-hat component forms part of the pre-assembled fixing rather than being an unrelated accessory added at the workface.

Combined with the washer & PX pin, it gives installers a prepared assembly that can be allocated to suitable fixtures before repetitive fastening begins.

That reduces the need to handle separate components at every fixing position.

For crews moving through repeated installation points, pre-assembly can help keep the intended washer, top hat & pin together instead of relying on loose parts being matched correctly during the work.

Thin Sheet Changes the Fixing Requirement

Sheet material can fail around a fixing before the pin itself becomes the problem.

That is why bearing area deserves attention.

The 22 mm metal washer provides a broader contact area against suitable thin material than the 8 mm pin head alone.

ICCONS identifies the assembly for quickly fastening suitable:

► Thin plastic sheeting
► Thin metal sheeting
► Fixtures with pre-existing holes

The washer should sit appropriately against the fixture without relying on excessive deformation to complete the installation.

Where the job instead requires conventional washered threaded hardware, compare Nuts & Washers.

Existing Holes Can Make the Assembly Particularly Useful

A bracket, plate or fixture that already has its fixing holes presents a different task from driving directly through an unprepared component.

PX washered top-hat assemblies are intended for suitable fixtures with pre-existing holes.

Before fastening, check:

► Hole position
► Hole condition
► Fixture thickness
► Washer seating area
► Substrate behind the fixture
► Selected pin length
► Equipment compatibility

The 22 mm washer needs enough suitable material around the fixing position to seat correctly against the fixture face.

A badly damaged, distorted or poorly positioned hole deserves assessment before the fixing is installed.

Concrete & Steel Require Their Own Installation Assessment

The same fixture can behave differently depending on what sits behind it.

These assemblies are intended for suitable fixing applications to concrete & steel.

Identify the actual base material before installation begins.

Concrete conditions can vary across a project while steel thickness & configuration can change between sections of the same installation.

Before repetitive fastening, establish:

► Substrate type
► Fixture type
► Fixture condition
► Required pin length
► Compatible low-velocity tool
► Appropriate system setup
► Suitable fixing position

Where direct fastening does not suit the connection, change the method rather than expecting the washer to compensate for an unsuitable base material.

Bigger Bearing Area Doesn't Make Every Fixture Suitable

A 22 mm washer improves support around the fixing point but it cannot correct every problem in the material underneath it.

Inspect thin fixtures for:

► Cracks
► Torn holes
► Distortion
► Corrosion
► Damaged edges
► Insufficient material around the hole
► Poor contact with the substrate

If the washer cannot seat properly, investigate the fixture before installing the pin.

The assembly works as a complete connection. Washer diameter alone should never be treated as proof that a damaged component can be fastened successfully.

Set Out Multiple Fixtures Before Fastening the First One

Rows of brackets, panels or sheet fixings quickly expose inconsistent positioning.

Where several fixing points need to align, establish the layout before loading the first assembly.

Confirm:

► Fixture centres
► Edge positions
► Hole alignment
► Clearances
► Changes in substrate
► Obstructions behind the work
► Finished position of the sheet or fixture

 Measuring & Layout Tools can assist where repeated fixtures need consistent positioning across a longer installation.

Accurate set-out also reduces the temptation to force a pre-existing fixture hole into a poorly positioned fixing point.

PX375 Compatibility Makes Equipment Planning Important

Consumables should be matched with the fastening equipment before they are sent to the work area.

PX washered top-hat drive pins are designed for use with the ICCONS PX375 & most other compatible low-velocity powder-actuated tools.

Before installation, confirm:

► Tool model
► Tool condition
► Consumable compatibility
► Selected PXWTH length
► Substrate
► Fixture
► Applicable operating requirements

Keeping the correct assemblies beside compatible equipment reduces interruptions once repetitive work begins.

For practical thinking around equipment readiness, read A tool is not just a tool. It’s a promise..

Look at the Washer After the First Fixing

The finished position of the washer can tell the installer whether the fixture is being supported as intended.

At an appropriate representative fixing point, inspect:

► Washer seating
► Fixture contact
► Pin seating
► Material distortion
► Movement around the fixing
► Unexpected substrate damage
► Overall fixture position

A washer that is sitting poorly, deforming the fixture or failing to support the intended area deserves investigation before the same setup is repeated.

Do not allow installation speed to outrun inspection.

20 mm, 25 mm or 30 mm?

Three similar boxes can serve different installation conditions.

The range provides 20 mm, 25 mm & 30 mm pin lengths while retaining the same washered top-hat concept.

Keep each length clearly separated during site preparation.

A practical stock arrangement can identify assemblies by:

► Part number
► Pin length
► Intended fixture
► Substrate
► Work zone
► Compatible equipment

Where several lengths are being used on the same project, avoid mixing loose assemblies into one container.

A small difference in pin length can be difficult to identify quickly once several consumables are together.

Don't Confuse Washered Top-Hat Pins With Standard PX Pins

The products may share the PX drive-pin system but the fixture interface is different.

A standard PX drive pin provides the pin head directly against the fixture.

The PXWTH assembly adds:

► 22 mm metal washer
► Top-hat component
► Pre-assembled configuration

That distinction matters when thin material or a fixture with an existing hole needs a broader bearing surface.

For general direct-fastening applications where a specialised washered assembly is unnecessary, broader Bolts & Fasteners & related fixing families can be considered according to the connection.

When Would a Drilled Fixing Be More Appropriate?

Direct fastening is useful where the substrate, fixture & system are compatible but it should not be forced into every connection.

Consider another fixing method where:

► The substrate is unsuitable
► A specified anchor is required
► The fixture is damaged around the hole
► Direct fastening produces inconsistent results
► A removable connection is required
► The project specification calls for another fastening system

For suitable concrete applications requiring a conventional drilled anchor, Anchor Bolts provide an alternative connection family.

Select the fixing method around the actual installation rather than trying to make the washered PX assembly perform a job outside its intended use.

A Practical Check for Repetitive Sheet Fixing

Before a full panel or row of fixtures is secured, use the first suitable connection to confirm the setup.

Ask:

Is the fixture suitable?

Thin plastic, thin metal sheet or another compatible fixture with an existing hole should be in sound condition.

Is there room for the washer?

The 22 mm washer needs an appropriate seating area around the fixing point.

Is the pin length correct?

Choose between the documented 20 mm, 25 mm & 30 mm configurations according to the installation.

Is the substrate suitable?

Confirm the concrete or steel base material before fastening.

Is the equipment compatible?

Use the PX375 or another suitable low-velocity powder-actuated tool.

Did the first connection finish correctly?

Inspect the washer, fixture & fixing before repeating the process.

Plan Consumables Around the Fixture, Not Just the Tool

A fastening tool can remain the same while the components being attached change throughout the day.

One work area may involve thin sheet while another uses fixtures with pre-existing holes or an entirely different fixing system.

Separate the washered top-hat assemblies from standard drive pins & other PX configurations before installation begins.

This helps crews identify the intended fixing from the fixture requirement rather than simply reaching for whichever PX consumable is closest to the tool.

Give Thin Material the Support the Fixing Was Designed For

The difference between a standard pin & a washered assembly becomes important at the face of the fixture.

Check the material around the hole, make sure the 22 mm washer has a suitable seating area then select the 20 mm, 25 mm or 30 mm configuration that belongs with the installation. Keep each length separated on site & confirm the first completed fixing before moving into repetitive work.

When the fixture, washer, top hat, pin & substrate are properly matched, the installer can use the pre-assembled system as intended rather than assembling a solution at every fixing point.

Choose ICCONS PX Washered With Top Hat Drive Pins where suitable thin sheet or pre-drilled fixtures need a pre-assembled PX fixing with increased bearing support.

Frequently Asked Questions

Yes. Fixtures with pre-existing holes are among the documented applications for the PX washered top-hat assembly. Confirm that the fixture, hole, substrate, pin length & equipment are suitable before installation.

The larger metal washer increases the bearing surface against the fixture, providing greater support around the fixing point than the pin head alone.

The documented range includes 20 mm, 25 mm & 30 mm drive-pin lengths, all with a 3.7 mm shank & 8 mm head.

Suitable thin plastic & metal sheeting are both identified applications for the washered top-hat assembly.

Yes. The range is intended for the PX375 & most other compatible low-velocity powder-actuated tools.

Do not assume it will. Inspect damaged material before fastening. The washer requires an appropriate seating area & should not be used simply to conceal a compromised fixture.
