Purpose-Built Roofing & Batten Fasteners

Otter Zip-Fixx Screws are purpose-built for Australian roofing, cladding & batten installation where the fastener needs to match both the material being fixed & the substrate underneath it. The range separates roofing screws from batten screws, giving roofers, builders & construction crews a clearer way to specify fasteners for roof sheeting, wall cladding & thin metal batten installation.

For other metal-fixing requirements, compare our Self-Drilling Screws to find suitable options based on material, thickness & application.

Choosing by application first — rather than simply screw diameter or length — helps reduce incorrect specification, installation problems & unnecessary rework on site.

What Are Otter Zip-Fixx Screws?

Otter Zip-Fixx Screws are specialised construction fasteners covering two distinct jobs: securing roofing or cladding to supporting battens & securing thin metal battens to structural substrates.

Zip-Fixx Roofing Screws secure compatible roof or cladding sheets to supporting timber or metal battens. Their design combines drilling, thread engagement, sheet retention & sealing at the fixing point.

Zip-Fixx Batten Screws secure thin metal battens to suitable timber trusses or steel purlins.

The selection logic is straightforward:

► Roof sheet → timber batten: Zip-Fixx Roofing Screw
► Roof sheet → suitable metal batten: Zip-Fixx Roofing Screw
► Cladding → suitable supporting substrate: Zip-Fixx Roofing Screw
► Thin metal batten → timber truss: Zip-Fixx Batten Screw
► Thin metal batten → suitable steel purlin: Zip-Fixx Batten Screw

Where the construction method calls for another fastening system, Roofing Nails & Fasteners provides alternative roofing fixing options.

Why Choose Otter Zip-Fixx Screws?

Fasteners represent a small part of a roofing project but incorrect selection can create disproportionately expensive problems.

A roofing screw needs to penetrate the intended substrate, develop suitable thread engagement, hold the sheet correctly & seal the penetration. A batten screw performs a different task: connecting the batten securely to the supporting structure.

Zip-Fixx provides application-specific features to address those requirements.

► Combination drill point – roofing variants are designed for compatible timber & metal batten applications.
► Coarse thread – provides engagement with the intended supporting material.
► Top-grip thread – helps hold roofing material firmly beneath the screw head.
► EPDM sealing washer – helps seal the roof penetration when correctly installed.
► Hex flanged head – supports efficient installation using compatible driving equipment.
► Class 4 roofing options – provide increased corrosion resistance for appropriate external applications.
► Selected COLORBOND® finishes – help compatible roofing screws integrate with common roofing colours.

When servicing existing roofing, replacement work may also require compatible Sealing Washer products depending on the condition & specification of the existing fixing.

Common Roofing, Cladding & Batten Applications

Zip-Fixx Screws suit new construction, reroofing, cladding installation, repair & maintenance work.

Metal roofing is a core application. Roofing screws connect compatible metal roof sheets to the supporting batten system, with screw length, substrate compatibility, corrosion protection & washer seating all requiring consideration before installation.

For wall cladding, suitable Zip-Fixx Roofing Screws can provide an application-specific fixing where the product specification matches the sheet, supporting material & exposure conditions.

The Zip-Fixx Batten Screw addresses a different connection. It provides a dedicated fastening solution for thin metal battens fixed to timber trusses or suitable steel purlins.

The 12g x 40 mm Zip-Fixx Batten Screw is specified for thin metal battens fixed to suitable steel purlins up to 1.5 mm thick.

Roof repair work requires additional assessment. Existing fixing holes should be checked for enlargement or damage while the sheet, substrate & sealing surface should be inspected before replacement.

Where repairs extend to flashing, laps or adjoining weatherproofing points, suitable Roof Sealants & Adhesives can support the wider weatherproofing requirements of the job.

Zip-Fixx Screw Selection Guide

Match the fastener to the connection being made rather than selecting solely by screw length.

Current Zip-Fixx Roofing Screw options include 6.2 mm x 50 mm & 6.2 mm x 65 mm sizes.

Depending on the selected roofing product, key specification points include:

► Combination drill point
► Coarse thread
► Top-grip thread beneath the head
► Hex flanged head
► EPDM sealing washer
► Hardened wire construction
► Cold-forged & roll-formed manufacture
► Class 4 galvanised options
► Selected COLORBOND® finishes

The 12g x 40 mm Zip-Fixx Batten Screw is designed around thin metal batten installation, with key specification points including:

► Self-drilling configuration
► Hex flanged head
► Coarse thread
► Hardened wire construction
► Cold-forged & roll-formed manufacture
► Class 3 galvanised finish
► Thin metal batten applications
► Timber truss compatibility
► Suitable steel purlins up to 1.5 mm

In practical terms: roofing screws secure the sheet while batten screws secure the batten.

Expert Tips for Better Zip-Fixx Installation

Correct installation helps the selected fastener perform as intended.

► Identify the substrate first. Don't select solely by screw length. Timber & steel have different drilling, penetration & thread-engagement requirements.
► Confirm drilling capacity. With steel substrates, verify that the selected screw is rated for the material thickness being penetrated.
► Match corrosion protection to exposure. Class 3 & Class 4 represent different corrosion-resistance levels. Exposure conditions & project requirements still determine which fastener is appropriate.
► Drive square to the surface. Angled installation can affect head seating & washer compression.
► Control installation torque. Drive roofing screws firmly enough to seat correctly without excessively crushing or distorting the EPDM washer.
► Inspect the finished seal. The washer should be consistently seated around the fixing point rather than visibly displaced.
► Check replacement holes. An enlarged or damaged fixing hole may require a different repair solution rather than another like-for-like screw.

For repetitive roofing & framing work, suitable Impact Drivers can support efficient fastening when paired with the correct socket & controlled driver setup.

Planning a Roofing Fastener Order

Running short of the correct fixing halfway through a roofing job costs more than the missing box of screws.

Before ordering, confirm:

► Sheet or cladding material
► Supporting substrate
► Substrate thickness where relevant
► Required screw diameter & length
► Drill-point capability
► Corrosion classification
► Required roofing colour or finish
► Sealing requirements
► Driver & socket compatibility
► Quantity required plus an appropriate job allowance
► Access & site-safety requirements

Crews completing full roofing installations can pair their fasteners with suitable Roofing Tools & Accessories before heading to site.
