Shaft Keyway Gauges

Shaft keyway gauges are specialized inspection tools used to verify keyway width, depth and profile on shafts and hubs. They enable fast go/no-go checking and tolerance confirmation before assembly, helping ensure proper key fit and torque transmission.

Available as sets or individual gauges for different standards and sizes, typically made from hardened steel with clear markings for reliable repeatability. Options include ergonomic handles and robust shop-floor designs, from Ultra & Insize.

Well suited for machine shops, production lines and QC departments where correct keyway fit prevents backlash, premature wear and drivetrain failures.
