Starrett 666S-10 Feeler Stock Roll 0.01 in Stainless Steel

Product Description

The STARRETT 666S-10 is a stainless steel feeler stock roll used for precision gap measurement and shim applications in mechanical, HVAC, and industrial service work. The roll measures 0.01 inches thick and 0.5 inches wide, providing a consistent, accurate thickness across its full 25-foot length. Stainless steel construction resists corrosion and holds calibration under repeated use. Technicians cut the stock to length as needed, making it a practical alternative to fixed-length feeler gauges in applications where custom sizing is required. This format is well suited for high-volume shops or field technicians who need an on-demand supply of precision shim material.

This feeler stock roll is used across a range of trade applications including HVAC equipment alignment, burner and heat exchanger clearance checks, motor and pump shaft alignment, and general mechanical service. The 0.01-inch thickness is a common measurement increment for checking tight tolerances on compressors, fan assemblies, and rotating equipment. The 25-foot roll length provides enough material for extended job use without frequent restocking. It is appropriate for both residential and light commercial service environments where precise gap measurement is part of routine maintenance or installation work.

Key Features

• 0.01-inch thickness for precise gap and clearance measurement
• 0.5-inch wide strip allows easy insertion into tight clearances
• 25-foot roll length provides cut-to-length flexibility for varied job requirements
• Stainless steel material resists corrosion and maintains dimensional stability
• Continuous roll format eliminates the fixed-length constraints of standard feeler gauges

Compatibility

Designed as a general-purpose feeler stock roll for use in any application requiring a 0.01-inch thickness stainless steel shim or gap-measurement strip.

Installation Notes

Use aviation snips, metal shears, or a bench cutter to cut the stock to the required length. Deburr all cut edges before inserting the strip into any precision clearance to avoid scoring mating surfaces. Always power down or de-energize equipment before performing any clearance or alignment check on rotating or electrically live assemblies. Handle the stock carefully, as the edges can be sharp.
