Starrett 52844 Feeler Gage 0.006 in Parallel Leaf 12 in

Product Description

The STARRETT 52844 is a single parallel-leaf feeler gage designed for precise gap and clearance measurement in mechanical and maintenance applications. The leaf measures 0.006 inches thick, 0.5 inches wide, and 12 inches long, providing consistent contact across the full length of the blade. Manufactured from tempered steel, the leaf resists deflection and retains its calibrated thickness under repeated use. This type of feeler gage is a standard hand tool for technicians who need accurate, repeatable clearance checks during assembly, adjustment, or inspection work.

Parallel-leaf feeler gages like the STARRETT 52844 are used across HVAC, mechanical, and general trade applications where precise gap measurement is required. Common uses include checking valve clearances, setting igniter and burner gaps on heating equipment, verifying bearing clearances, and confirming spacing tolerances during equipment installation or preventive maintenance. The 12-inch blade length makes it suitable for reaching into confined spaces on larger equipment assemblies.

Key Features

• 0.006 inch calibrated blade thickness for precise gap measurement
• Parallel leaf style maintains consistent width across the full 12 inch length
• Tempered steel construction resists bending and holds calibration under regular use
• 0.5 inch blade width provides stable contact surface during measurement
• 12 inch length allows reach into deeper or more confined assemblies

Compatibility

Designed as a standard parallel-leaf feeler gage for general mechanical measurement and gap-checking applications across trade and industrial use.

Installation Notes

Feeler gages are a hand-measurement tool requiring no installation. Power down and de-energize any equipment before inserting the blade into a gap or clearance point. Do not force the blade into a gap narrower than its rated thickness, as this can deform the leaf and compromise measurement accuracy. Store the blade clean and flat to preserve calibration.
