Precision Brand 77740 Feeler Gauge Set

This 12-piece feeler gauge set from Precision Brand supplies stainless-steel blades each measuring 0.0005 inch thick and 12 inches long. The long-blade design suits mechanics and machinists who need to reach deep or recessed gaps during setup and inspection work. Blades are marked in inch graduations and meet ASTM A-666 chemistry standards with a tolerance of ±10 percent.

Thermal Behaviour and Power Draw

As a purely mechanical tool the gauge set produces no heat, draws no electricity and creates no audible noise during use. Stainless-steel construction resists corrosion so the blades stay dimensionally stable across normal workshop temperatures. No external power source or cooling is required for operation.

Build Quality and Daily Use

Uncoated stainless blades avoid plating wear that could alter the critical 0.0005-inch thickness over time. The half-inch blade width and 12-inch length provide reach without excessive flex when sliding into tight clearances. Non-magnetic material prevents ferrous debris from clinging to the blades during engine or bearing checks. Not suited for users who require metric markings or a wider range of thicknesses in a single pack.

Questions about this item

How do I install the 0.0005 in feeler gauge blades without bending them?

Insert the long 12 in stainless steel blades carefully into the gap; the uncoated finish and +/-10 percent tolerance mean excess force can permanently deform the thin material.

What maintenance will the stainless steel gauge set need over time?

Wipe the uncoated blades clean after each use and store them dry to prevent surface corrosion; the ASTM A-666 stainless steel resists rust but is not immune to moisture.

What is the first limit reached when using these gauges continuously?

The 0.0005 in thickness and +/-10 percent tolerance make the blades prone to permanent bending before any wear appears on the stainless steel edges.
