Standard Knurls

CJWinter designs and supplies knurls to customer specifications.

Knurls can be supplied in various types to suit individual requirements. Our knurl styles fit most knurl holders and include:

Diametral Pitch Knurls

Diametral Pitch Knurls are made to American Standards (ASA B5.30 1958). Diametral Pitch Knurls produce the D.P. number of teeth per inch of diameter. Rolled circular pitch knurls produce the T.P.I. number of teeth per inch of circumference measured normally to the teeth.
