Lead inspection is both an API mandated requirement and an industry wide practice. Defined as the distance between threads as measured on a plane parallel to the centerline of the threaded part, lead variation has a direct effect on stand-off, thread flank engagement, and make-up. Lead error is most commonly generated by manual and CNC lathes not cutting properly. BESTO lead gages provide dimensional verification of product print data.
The lead gage inspects both internal and external thread leads using contact points that seat in the threads of a part. The
pitch of the thread determines the diameter of the contact points required for taking measurements.
