Starrett 52837 Feeler Gage 0.001 in Parallel Leaf Tempered Steel

Product Description

The STARRETT 52837 is a single parallel-leaf feeler gage used to measure precise gaps, clearances, and tolerances in mechanical assemblies. The leaf measures 0.001 inches thick, 0.5 inches wide, and 12 inches long, providing consistent and reliable readings across its full length. Constructed from tempered steel, the leaf resists deflection and wear during repeated use. This type of feeler gage is a standard hand tool for HVAC technicians, machinists, plumbers, and general trade mechanics who need accurate gap measurement during installation, alignment, and maintenance tasks.

The STARRETT 52837 is suited for residential and commercial applications where precise clearance checks are required. Common uses include checking valve clearances, burner orifice gaps, bearing fits, and component alignment. The 12-inch parallel leaf length accommodates a wide range of measurement scenarios, and the 0.5-inch width provides a stable contact surface on flat or near-flat mating surfaces. The tempered steel construction holds calibration under normal shop and field conditions.

Key Features

• 0.001-inch thickness for precision gap and clearance measurement
• Parallel leaf style ensures uniform thickness along the full 12-inch length
• 0.5-inch leaf width provides stable surface contact
• Tempered steel construction resists flex and wear
• 12-inch length accommodates a wide variety of measurement applications

Compatibility

Designed as an OEM-style precision measurement tool suitable for general trade use wherever a 0.001-inch parallel feeler gage leaf is required.

Installation Notes

Feeler gages are used by HVAC technicians, machinists, and trade professionals to verify clearances without powered equipment. Ensure the surfaces being measured are clean and free of debris before inserting the leaf. Avoid bending or forcing the leaf into a gap, as this can alter the leaf geometry and affect measurement accuracy. Store flat and away from moisture to maintain calibration.
