Starrett 64210 Feeler Stock Roll 0.0005 in Tempered Steel

Product Description

The STARRETT 64210 is a precision feeler stock roll used for measuring and setting tight clearances in mechanical assemblies, valves, and equipment alignments. This roll is manufactured from tempered steel and measures 0.0005 inches thick, 0.5 inches wide, and 25 feet long. The extra-thin gauge makes it suitable for the most precise clearance checks where standard feeler gauges do not provide enough flexibility or length. HVAC technicians, machinists, and maintenance professionals use feeler stock rolls to cut custom-length strips for gap and tolerance verification in a wide range of industrial and mechanical applications.

This feeler stock roll is suited for trade and industrial environments where precise clearance measurement is required. Common applications include checking valve seating clearances, setting contact gaps, verifying bearing tolerances, and fitting custom shim strips. The 25-foot roll format allows technicians to cut strips to any required length on the job, reducing waste and providing flexibility that fixed-length gauges cannot match. The 0.5-inch width is a standard format compatible with most feeler stock cutting and bending workflows.

Key Features

• Tempered steel construction for dimensional stability and resistance to deformation under load
• Ultra-thin 0.0005-inch thickness for measuring extremely tight clearances
• 25-foot roll length allows custom strip cutting to any required measurement
• 0.5-inch width is a standard feeler stock format compatible with common cutting tools
• Roll format is compact and easy to store in a tool kit or service van

Compatibility

Designed as a standard-format feeler stock roll for use in mechanical, HVAC, and industrial maintenance applications where 0.0005-inch clearance measurement is required.

Installation Notes

Feeler stock is handled and cut by machinists, HVAC technicians, and mechanical maintenance professionals. Use aviation snips, a bench shear, or a dedicated feeler stock cutter to cut strips to the required length. Edges cut from the roll may be sharp; deburr cut ends before use in precision assemblies. Keep the roll clean and dry to prevent surface corrosion that could affect measurement accuracy.
