A Higbee cut is a specific cut added to a screw thread to produce a blunt start, instead of the sharp end of the unmodified screw thread. It is named for its inventor Clinton Higbee. The presence of a Higbee cut on both male and female threads eliminates the chance of cross threading. A blunt start thread possessing a Higbee cut is also known as a convoluted thread. [1]
The Higbee cut is commonly used on fire hose couplings' threads. [2] The presence of the Higbee cut and the location of the start of the thread are often marked on couplings to assist with assembly. [3]
Gauging used to inspect machine threads often includes a Higbee cut. [4]
Clinton Higbee invented and patented the blunt start thread in 1891. [5]
