Starrett 667S-5 Feeler Gage 0.005 in Stainless Steel Parallel Leaf

Product Description

The STARRETT 667S-5 is a single-leaf feeler gage used for measuring precise gaps, clearances, and tolerances in mechanical assemblies and equipment. The leaf measures 0.005 inches thick, 0.5 inches wide, and 12 inches long with a parallel profile that maintains consistent thickness along the full length. Constructed from stainless steel, it resists corrosion and wear in shop, field, and service environments. Technicians and mechanics use this gage to verify valve clearances, spark plug gaps, bearing fits, and similar close-tolerance measurements where accuracy is critical.

This feeler gage is suited for use in HVAC, refrigeration, and general mechanical service applications where precise clearance verification is required. The 12-inch parallel leaf provides enough reach for accessing components inside equipment cabinets, compressors, and motor housings. Its stainless steel construction makes it appropriate for both shop bench work and field service calls where moisture or chemical exposure may be present.

Key Features

• 0.005-inch blade thickness for precise gap and clearance measurement
• Parallel leaf style maintains uniform thickness across the full 12-inch length
• Stainless steel construction resists corrosion and wear
• 0.5-inch blade width provides adequate surface contact for stable readings
• Single-leaf format for targeted use at a specific tolerance dimension

Compatibility

Designed as a general-purpose feeler gage leaf suitable for measuring clearances in mechanical, HVAC, refrigeration, and related trade service applications where a 0.005-inch tolerance check is required.

Installation Notes

This tool is used by licensed HVAC technicians, mechanics, and trade professionals for gap and clearance verification. Power down and de-energize equipment before inserting the gage into any rotating or electrically live assembly. Clean the gage blade before and after use to prevent contamination of precision measurement surfaces. Do not force or bend the blade, as permanent deformation will compromise accuracy.
