Starrett 52819 Feeler Stock Roll 0.022 in Tempered Steel

Product Description

The STARRETT 52819 is a tempered steel feeler stock roll used to measure and set precise gaps in mechanical assemblies, valves, bearings, and other close-tolerance applications. The roll measures 0.022 inches thick and 0.5 inches wide, with a 20-foot length that allows technicians to cut custom-length strips as the job requires. Tempered steel construction provides the stiffness and dimensional stability needed for accurate feeler gauge work across a wide range of trade applications. HVAC technicians, machinists, and maintenance mechanics rely on feeler stock when factory-formed gauge blades are not the right length or shape for the access point.

This feeler stock roll is suited for residential and commercial service environments where non-standard gap measurements are needed. Common applications include setting valve clearances, checking bearing tolerances, verifying burner orifice spacing, and shimming components during alignment work. The 20-foot roll length gives field technicians enough material to stock a service vehicle and cut strips to length on-site, reducing the need to carry multiple pre-formed gauge sets.

Key Features

• 0.022 inch thickness for precise gap measurement and setting in close-tolerance assemblies
• 0.5 inch width provides a stable bearing surface across the measured gap
• 20-foot roll length allows on-site cutting to any required strip length
• Tempered steel construction delivers consistent stiffness and dimensional accuracy
• Single roll packaged individually, ready for field or shop use

Compatibility

Designed as a general-purpose feeler stock roll for use in any application requiring 0.022 inch gap measurement, including mechanical, HVAC, plumbing, and maintenance trade work.

Installation Notes

Cut strips to the required length using aviation snips or a sharp bench shear — avoid bending or kinking the stock during cutting, as deformation will affect measurement accuracy. Power down or de-energize any equipment before inserting feeler stock into tight clearances near moving parts or live electrical components. Handle cut edges carefully, as sheared tempered steel can produce sharp burrs.
