Parts, Attachments & Support for Precision Tool Setups

Already own the Starrett tool but need the component that completes the setup? Starrett Accessories help measuring, inspection, layout & workshop equipment stay useful across changing jobs, whether you're replacing a worn component, changing how an instrument contacts the work or adding an attachment for a particular measuring task.

Compatibility matters more here than simply choosing by appearance. Model or series, thread, mounting method, contact style, dimensions & intended application can determine whether two similar-looking components actually belong together. Checking those details before ordering protects the instrument, reduces downtime & avoids filling the workshop drawer with parts that almost fit.

For dimensional inspection equipment, Testing & Measurement Tools is the natural route into the broader measuring system. Where the job is about marking, positioning or transferring dimensions onto the work, Measuring & Layout Tools connects the accessory with the wider layout process.

A small accessory can restore a trusted tool, change the way it reaches a measurement or complete a setup that would otherwise sit unused. The key is matching the component to both the instrument & the job.

What Are Starrett Accessories?

Supporting Components for Measuring, Inspection, Layout & Cutting

Not every workshop problem calls for another complete tool.

Sometimes the missing piece is a contact point, holder, attachment, replacement component or supporting part designed to work with equipment already on the bench.

Across Starrett's wider tool system, accessories can include:

► Indicator contact points for compatible measuring applications
► Indicator holders, connectors & fixture components
► Micrometer accessories & suitable contact attachments
► Precision rule accessories & holders
► Trammel attachments for transferring or scribing larger dimensions
► Replacement components for compatible serviceable tools
► Cases & protective items for suitable measuring equipment
► Supporting power-tool components used with compatible cutting equipment

These aren't universal add-ons.

A Starrett accessory should be selected around the specific tool family, model & application it was designed to support.

Why Choose Starrett Accessories?

Keep Useful Equipment in Service

A damaged supporting component doesn't automatically mean the main instrument needs replacing.

Where the tool remains serviceable & the correct replacement is available, changing the affected component can be a practical way to restore the setup.

That matters particularly around established inspection stations where operators already know the instrument, understand its behaviour & have built repeatable processes around it.

Adapt the Instrument to the Measurement

Nothing has to be broken for an accessory to be useful.

The next component may simply present a different measuring challenge.

An indicator might need another contact arrangement. A layout job may require a larger transferred radius. A compatible instrument might need different fixturing to reach the feature being inspected.

Instead of asking what accessories are available, start with what the existing tool needs to accomplish.

Preserve the Integrity of a Precision Setup

Close enough isn't a useful compatibility standard around measuring equipment.

Threads, mounting surfaces, contact geometry & component dimensions all affect how a precision setup goes together.

Using the correct matching part also avoids unnecessary force on delicate threads, stems, spindles & mounting points.

Common Applications

Indicator & Inspection Setups

An indicator can only report movement it can physically reach.

Contact shape, mounting position & fixture arrangement therefore become part of the measuring system.

Compatible contact points, holders & connectors can help position suitable Starrett indicators around shoulders, faces, recesses or other workpiece features.

That flexibility is useful in machining, quality control, maintenance & workshop inspection where components rarely arrive in one convenient shape.

Precision Measurement

Micrometers & other dimensional instruments are designed around specific measuring tasks, but suitable accessories can support storage, data handling or particular contact requirements depending on the model.

Where tolerances move beyond practical tape or rule measurement, the accessory should complement the precision instrument rather than introduce another uncontrolled variable.

Layout & Dimension Transfer

Large-radius layout creates a different problem from ordinary bench measurement.

Compatible trammel attachments can support the transfer, measurement or scribing of larger dimensions where conventional dividers don't provide enough reach.

Once the dimension becomes a physical mark, Metal Cutting & Grinding Tools can support fabrication jobs progressing from layout into cutting & edge preparation.

Machining & Fabrication

A workshop can inspect an outside face in the morning & encounter a bore, shoulder, curved component or awkward fixture later that day.

Changing workpiece geometry is one reason experienced operators build adaptable measuring setups rather than expecting one configuration to reach everything.

Workshop Equipment supports the wider bench & machine environment, while Clamps & Vises can help secure suitable work during layout, checking & fabrication.

Maintenance & Repair

It's usually the little missing part that becomes important once the machine is already apart.

Keeping frequently used accessories identified & organised can prevent an otherwise functional measuring tool from becoming unusable halfway through a repair.

Cutting Equipment

Starrett's wider product system extends beyond precision measurement into saws & power-tool accessories.

Supporting components used around cutting equipment need the same compatibility-first approach: identify the cutting tool, machine interface & application before choosing what connects them.

Power Tool Accessories is the stronger destination when the requirement shifts from inspection into powered cutting.

Product Selection Guide

Start With the Tool Sitting in Front of You

Forget the accessory catalogue for a moment.

Record what you already own.

Replacement Part or New Capability?

This distinction can shorten the search considerably.

Replacing something? Match the original component as closely as the manufacturer's compatibility information requires.

Changing the setup? Work backwards from the new measuring task & identify which compatible attachment creates the required contact, reach or mounting arrangement.

Contact Geometry Deserves Attention

A measuring contact is the physical interface between the instrument & the component.

Flat faces, curved surfaces, recesses, narrow features & unusual profiles don't necessarily suit the same contact.

Consider where the contact will sit, which direction movement occurs & whether the setup can repeat that position reliably.

Don't Accessorise a Problem That Needs Repair

Inconsistent readings aren't automatically an accessory problem.

Inspect the main instrument, contact surfaces, mounting arrangement & general condition before buying components in an attempt to correct unexplained measurement variation.

Precision equipment needs a sound foundation before another part is added.

Expert Tips

Put the Model Number in Your Phone

A quick photo of the tool's identification can save a surprising amount of guesswork later.

Capture the model or series, existing attachment & any relevant connection before leaving the workshop to source a component.

Threads Should Engage Without an Argument

If a precision accessory needs force to start, stop.

A similar diameter doesn't guarantee the same thread specification, forcing the connection can damage both components.

Clean Interfaces Before Testing Fit

Fine swarf, dried residue or workshop grime can interfere with threads, mounting faces & measuring contacts.

Careful cleaning can solve a fit or repeatability problem before replacement parts become involved.

Give Small Components a Permanent Home

Indicator contacts & specialist attachments are easy to lose because they're small enough to disappear underneath everything else.

Keep dedicated accessories with their instrument or in clearly identified storage.

Tools Storage & Organization can help separate precision components from heavier equipment that can damage fine threads, points & contact surfaces.

Record Setups Worth Repeating

Found a combination that works particularly well for a recurring inspection?

Take a photo or record the configuration.

Documenting contact type, holder position & instrument arrangement gives the next operator a proven starting point instead of another trial-and-error exercise.

A tool is not just a tool. It’s a promise. looks more broadly at why equipment selection, condition & use all contribute to dependable trade work.

Check the Result After Changing the Setup

Installing a compatible accessory doesn't remove the need to verify the measuring system.

After changing contacts, holders or another measurement-related component, check the setup against an appropriate known reference before relying on it for critical inspection.
