Starrett 666S-1 Feeler Stock Roll 0.001 in Stainless Steel

Product Description

The STARRETT 666S-1 is a stainless steel feeler stock roll used for precision gap measurement and shimming applications in trade and industrial settings. At 0.001 inches thick and 0.5 inches wide, this roll provides a continuous 25-foot length of consistent-thickness material that technicians can cut to any required length. The stainless steel construction resists corrosion and maintains dimensional stability under repeated use. HVAC technicians, machinists, and field service professionals use feeler stock to check clearances, set tolerances, and fabricate custom shims without relying on pre-cut gauges.

This feeler stock roll is suited for residential and commercial service environments where precise gap or clearance measurement is required. Common applications include checking valve clearances, setting bearing tolerances, aligning components, and fabricating shim stock in the field. The 25-foot roll format reduces waste by allowing the technician to cut only the length needed for each job. Its compact roll form fits easily in a tool bag or service kit.

Key Features

• 0.001 inch thickness for precision clearance and gap measurement
• 0.5 inch width accommodates a wide range of measurement tasks
• 25-foot continuous roll allows custom cut lengths
• Stainless steel construction provides corrosion resistance and dimensional stability
• Roll format reduces on-hand inventory compared to pre-cut gauge sets

Compatibility

Designed as a general-purpose feeler and shim stock roll suitable for HVAC, mechanical, and industrial service applications requiring 0.001 inch thickness material.

Installation Notes

Cut feeler stock to the required length using tin snips or metal shears rated for thin gauge material. Edges after cutting may be sharp — deburr before handling without gloves. Always verify the gap or clearance specification against the equipment manufacturer's service documentation before use. No special tools or certifications are required to use feeler stock, but all work on live mechanical or HVAC systems should follow applicable lockout/tagout procedures.
