Starrett 667S-2 Feeler Gage 0.002 in Parallel Leaf

Product Description

The STARRETT 667S-2 is a single parallel-leaf feeler gage used to measure and verify precise gap clearances in mechanical and HVAC service applications. The leaf measures 0.002 inches thick, 0.5 inches wide, and 12 inches long, providing consistent contact across the full length of the gap being checked. Constructed from stainless steel, the leaf resists corrosion and maintains dimensional stability under repeated use. This gage is a standard precision measurement tool used by HVAC technicians, millwrights, plumbers, and electricians when setting valve clearances, checking bearing fits, or verifying part tolerances.

The 667S-2 is suited for residential and commercial service work where tight clearance verification is required. Typical applications include checking burner orifice alignment, heat exchanger component clearances, motor bearing end play, and general mechanical gap inspection. The 12-inch parallel leaf length accommodates a wide range of inspection points, and the 0.5-inch width provides a stable surface contact when checking flat or parallel mating faces.

Key Features

• 0.002-inch thickness for precise fine-gap measurement
• Parallel leaf style ensures uniform thickness across the full 12-inch length
• Stainless steel construction resists corrosion and wear
• 0.5-inch leaf width provides stable contact on flat mating surfaces
• Single-leaf format allows targeted use without handling a full gage set

Compatibility

Designed as an OEM-style replacement or supplemental leaf for use with standard parallel-leaf feeler gage applications requiring a 0.002-inch thickness measurement.

Installation Notes

Feeler gages require no installation but should be used only on de-energized equipment with all power and fuel sources isolated before inserting the leaf into any clearance gap. Clean the leaf and mating surfaces before use to prevent contamination from affecting the measurement. Avoid bending or forcing the leaf, as permanent deformation will invalidate the measurement accuracy. Wipe the leaf clean and store it flat after use to preserve calibration.
