Feeler Gauge Sets – Standard US Inch Sizes

US Inch Feeler Gauge Sets

All feeler gage sets feature a metal holder to protect the blades when not in use and consist of many popular styles and sizes. The user can “fan” out the blades for easy selection, and then return the unused gages back into the holder. The screw and lock nut can be tightened to secure the blades in working position. For easy identification, each blade is permanently marked with the blade thickness. All gauges have smooth rounded edges and ends for comfort and safety.

Our steel blades are made of the finest quality high carbon steel that has been hardened and tempered for superior wear resistance. Our stainless steel blades are made of fully hardened and polished 300 series stainless steel noted for its outstanding resistance to corrosion. Both metals provide stable and dependable accuracy. In addition to our US inch Feeler Blade sets, we also have metric feeler gage size sets for your next project.
