Starrett 52803 Feeler Stock Roll 0.006 in Tempered Steel

Product Description

The STARRETT 52803 is a tempered steel feeler stock roll used to measure and set precise gaps in mechanical and HVAC assemblies. At 0.006 inches thick and 0.5 inches wide with 25 feet of usable length, this roll provides enough material for repeated cut-to-length use across a wide range of service applications. Tempered steel construction gives the stock consistent stiffness and resistance to deformation, which is critical when checking tight tolerances on burner orifices, valve seats, bearing clearances, and similar components. Technicians cut strips to length as needed, making this roll an efficient shop and field consumable.

This feeler stock is used by HVAC technicians, machinists, and maintenance professionals wherever precise gap measurement or setting is required. Common applications include checking heat exchanger clearances, setting igniter gaps, verifying valve and seal seating surfaces, and general mechanical alignment work in residential and light commercial equipment. The 0.5-inch width accommodates most standard feeler gauge applications without trimming to width.

Key Features

• Tempered steel construction maintains consistent thickness under repeated flexing
• 0.006 inch thickness suits tight-tolerance gap checks common in HVAC and mechanical service
• 25-foot roll length allows multiple cut-to-length strips for field and shop use
• 0.5 inch width fits standard gap-measurement tasks without additional trimming
• Single-roll packaging keeps stock organized and protected from kinking

Compatibility

Designed as a general-purpose feeler stock for use in HVAC, mechanical, and maintenance applications requiring a 0.006 inch gap gauge material in tempered steel.

Installation Notes

Feeler stock is installed or used by qualified HVAC technicians, machinists, or maintenance professionals. Power down and de-energize any equipment before inserting feeler stock into electrical or ignition assemblies. Use sharp shop shears or a metal cutter to cut strips cleanly; ragged edges can introduce measurement error. Store the roll flat or loosely coiled to prevent permanent set in the material.
