Starrett 52814 Feeler Stock Roll 0.017 in Tempered Steel

Product Description

The STARRETT 52814 is a tempered steel feeler stock roll used to check and set precise clearances in mechanical assemblies, HVAC equipment, and industrial machinery. At 0.017 inches thick and 0.5 inches wide, this roll provides a continuous 25-foot supply of flat, consistent-thickness shim and feeler material. Tempered steel construction delivers the hardness and spring-back needed for accurate gap measurement and repeated use. Technicians cut the material to any required length, making it a flexible alternative to individual feeler gauge blades. It is a standard bench-stock item in HVAC, mechanical, and precision maintenance shops.

This feeler stock roll is suited for residential and commercial HVAC service, refrigeration equipment alignment, compressor valve clearance checks, and general mechanical maintenance applications. Technicians use it wherever a specific gap or clearance must be verified or set, including bearing fits, valve seats, and mating surfaces. The 25-foot roll length makes it practical for both single-job use and ongoing shop inventory. Its 0.017-inch thickness corresponds to a common clearance specification found across many equipment types.

Key Features

• Tempered steel construction provides consistent hardness and accurate thickness across the full roll length
• 0.017-inch thickness covers a common clearance specification used in HVAC, refrigeration, and mechanical assemblies
• 0.5-inch width allows use in confined spaces and tight access areas
• 25-foot continuous roll — cut to any required length for the job
• Flat stock format works as feeler gauge material, shim stock, or custom-length gauge strips

Compatibility

Designed as a general-purpose tempered steel feeler and shim stock suitable for HVAC equipment service, refrigeration compressor maintenance, and precision mechanical assembly work where a 0.017-inch clearance specification applies.

Installation Notes

Cut the stock to the required length using metal shears or a utility knife with a straightedge — avoid bending or kinking the material near the measurement area, as deformation affects accuracy. Always de-energize and lock out equipment before using feeler stock to check internal clearances or valve gaps. Handle cut edges with care, as tempered steel edges are sharp. Follow the equipment manufacturer's published clearance specifications when using this stock to set or verify gaps.
