Starrett 667S-15 Feeler Gage 0.015 in Stainless Steel

Product Description

The STARRETT 667S-15 is a single parallel-leaf feeler gage used to measure and verify precise clearances between mating surfaces, moving parts, and assemblies. The leaf measures 0.015 inches thick, 0.5 inches wide, and 12 inches long, providing a consistent measuring surface across the full working length. Constructed from stainless steel, it resists corrosion and maintains dimensional stability in shop environments. HVAC technicians, machinists, and field service technicians use feeler gages like this one when setting valve clearances, checking air gaps, verifying blade clearances, or confirming tolerances during equipment commissioning and maintenance.

This feeler gage leaf is suited for applications requiring a 0.015-inch gap measurement in HVAC, mechanical, and general trade service work. The parallel-leaf profile delivers a uniform thickness from tip to heel, which is critical for accurate gap checks on compressor valve assemblies, blower wheel clearances, motor end-play, and similar close-tolerance fits. Its 12-inch length allows reach into tight or recessed assemblies without a handle obstruction.

Key Features

• 0.015-inch nominal thickness for precise gap measurement
• Parallel-leaf style maintains uniform thickness along the full 12-inch length
• Stainless steel construction resists rust and corrosion in wet or humid service environments
• 0.5-inch width provides stable blade contact on flat mating surfaces
• Single-leaf format allows use as a replacement blade or standalone gage

Compatibility

Designed as an OEM-style replacement or supplemental leaf for standard feeler gage sets requiring a 0.015-inch stainless steel parallel blade with a 12-inch leaf length.

Installation Notes

Feeler gages are used by HVAC technicians, machinists, and mechanical service professionals during inspection and adjustment procedures. Power down or lock out any equipment before inserting a feeler gage into rotating or pressurized assemblies. Use only enough insertion force to achieve a slight drag fit — forcing the blade can damage the leaf or distort the measured gap. Keep the blade clean and free of burrs to maintain measurement accuracy.
