Starrett S667AS Feeler Gage Set 32-leaf Stainless Steel

Product Description

The STARRETT S667AS is a 32-leaf parallel-blade feeler gage set designed for precise gap measurement in mechanical assembly, engine work, and equipment maintenance. Leaves are manufactured from stainless steel for corrosion resistance and long service life. The set covers a thickness range of 0.0010 inches to 0.3000 inches, making it suitable for checking valve clearances, bearing fits, and machined-surface tolerances. Each leaf has a parallel profile with a 12-inch length and 0.5-inch width. The assembled set closes to 12 inches in length and 0.5 inches in width, keeping it compact for use in a tool kit or service bag. Total weight is 1.15 pounds.

This feeler gage set is used in HVAC, refrigeration, automotive, and general mechanical service applications where controlled gap measurement is required. Typical users include HVAC technicians checking compressor or motor clearances, machinists verifying fits during assembly, and maintenance professionals calibrating equipment. The stainless steel construction handles environments where moisture or mild chemicals are present, making it appropriate for both shop and field use.

Key Features

• 32 parallel stainless steel leaves spanning 0.0010 to 0.3000 inches
• Parallel leaf style for consistent, repeatable gap readings
• 12-inch leaf length provides reach into deep or recessed clearances
• 0.5-inch leaf width suits standard gap-checking applications
• Stainless steel construction resists corrosion and wear
• Compact closed dimensions of 12 inches by 0.5 inches for easy storage

Compatibility

Designed as a general-purpose feeler gage set for mechanical and HVAC service applications requiring parallel-blade gap measurement across the 0.0010 to 0.3000 inch thickness range.

Installation Notes

Feeler gages are a measurement tool, not an installed component. Wipe leaves clean before and after use to prevent debris from affecting measurement accuracy. Do not force a leaf into a gap; select the appropriate thickness by feel with light drag only. Store the set closed and away from abrasive materials to protect the leaf surfaces.
