Precision Brand 77420 Thickness Gage Stainless Steel

Product Description

The PRECISION BRAND 77420 is a single-leaf stainless steel thickness gage used to measure gaps, clearances, and tolerances in mechanical assemblies. Measuring 0.012 inches thick, 0.5 inches wide, and 5 inches long, it provides a precise reference for checking fits between mating parts. The stainless steel construction resists corrosion and wear, making it suitable for use in shop environments where contact with oils, coolants, or moisture is common. Machinists, HVAC technicians, and service professionals reach for thickness gages when verifying valve clearances, motor air gaps, and bearing fits during installation or maintenance work.

This gage is suited for residential and commercial service applications where accurate gap measurement is required. Common uses include checking compressor valve clearances, fan blade tip clearances, and general mechanical fit verification. At 0.012 inches, this leaf falls within a commonly specified tolerance range for light-duty mechanical clearance checks. It is sold as a single pack and is intended for hand use without special tooling.

Key Features

• 0.012-inch thickness provides a precise gap reference for close-tolerance clearance checks
• Stainless steel construction resists corrosion, oils, and shop fluids
• 0.5-inch width and 5-inch length allow access to most standard clearance points
• Single-leaf format for straightforward, no-setup gap measurement
• Minimum order quantity of 1 pack for flexible purchasing

Compatibility

Designed as a general-purpose thickness gage for use in mechanical, HVAC, plumbing, and electrical service applications requiring gap clearance verification within the 0.012-inch specification range.

Installation Notes

Thickness gages are used by technicians and machinists during inspection and adjustment procedures. Always power down or de-energize any equipment before inserting a gage into a clearance point near moving or energized components. Insert the leaf parallel to the gap and without forcing it, as bending or overloading the blade will affect accuracy. Follow equipment manufacturer specifications for the required clearance value before selecting the appropriate gage leaf.
