Starrett Feeler Gauge Stock Roll 666-3 .003 in 25 ft measurement tool

Precision Feeler Stock

The Starrett 666-3 feeler gauge stock roll supplies 25 feet of straight steel blade material in a .003 inch thickness. It is intended for machinists, toolmakers and maintenance technicians who need to cut custom-length feelers for setting clearances, checking gaps or shimming assemblies. The unfinished steel surface and inch markings with metric equivalents support precise layout work in workshop and inspection environments.

Dispensing Case Integration

A plastic dispensing case is included to protect the coil and allow controlled feed during cutting. This packaging keeps the stock flat and free from damage while it sits on a bench or in a tool drawer. The 1/2 inch blade width provides a consistent reference edge for marking and shearing individual blades to the exact length required by the job.

Replaces Bulk Shim Stock

This roll upgrades from generic shim material that lacks certified tolerance or consistent thickness. The +/- .0002 inch tolerance ensures repeatable gap measurements across every cut piece. It is not suited for applications requiring non-magnetic or non-marring properties, nor for users who need pre-cut blade assortments in a folding holder.
