Starrett 52838 Feeler Gage 0.0015 in Parallel Leaf Steel

Product Description

The STARRETT 52838 is a single-leaf feeler gage used to measure precise gaps and clearances in mechanical assemblies, valve seats, bearing housings, and similar close-tolerance applications. The leaf measures 0.0015 inches thick, 0.5 inches wide, and 12 inches long, making it suitable for reaching into tight or extended clearance zones. Constructed from tempered steel, the leaf maintains dimensional stability under repeated use and resists permanent deformation from bending. The parallel leaf style provides consistent thickness across the full length of the blade. Licensed trades and experienced technicians use feeler gages like this one during equipment assembly, calibration, and preventive maintenance procedures.

This feeler gage is well suited for HVAC technicians checking compressor valve clearances, electricians verifying contact gaps in switchgear or relays, and general mechanical trades performing tolerance checks on rotating equipment or flanged assemblies. The 12-inch blade length allows access to recessed measurement points that shorter blades cannot reach. The 0.0015-inch thickness addresses very fine gap tolerances common in precision mechanical and electrical contact applications.

Key Features

• Tempered steel construction for durability and resistance to deformation
• Parallel leaf style ensures uniform 0.0015-inch thickness along the full 12-inch length
• 0.5-inch blade width provides stable contact surface for accurate gap readings
• 12-inch blade length allows access to deep or recessed clearance points
• Single-leaf format for direct insertion without additional leaves interfering with the measurement

Compatibility

Designed as a standard feeler gage leaf for general-purpose gap and clearance measurement in mechanical, HVAC, electrical, and industrial maintenance applications.

Installation Notes

Feeler gages are hand-measurement tools and require no installation. Before use, de-energize or lock out any equipment being serviced per applicable OSHA lockout/tagout procedures. Insert the blade with light hand pressure into the gap being measured — forcing the blade can bend the leaf and introduce measurement error. Keep the blade clean and free of oil buildup for consistent readings.
