Rules & Gauges

General offers Machinists and Engineers three classes of steel rules: economy (good), industrial (better) and UltraTest (best). Options include a satin chrome or stainless steel finish, a rigid or flexible bar, and various combinations of industry-standard etched graduations on one or both ends. We also offer leaf, feeler, screw pitch, wire, and drill gauges, each optimized to precisely measure the thickness of a specific kind of metal part.
