THREADED RODS & STUDS
DIN 939 Tap-End Studs
Tap-end studs with an approximately 1.25d metal end for specified machinery connections.
Product Overview
A tap-end stud has a screw-in end for the tapped component and a separate nut end for clamping the removable part. The metal-end length and fit must suit the base material and tapped-hole design. Nominal working length and overall length are different dimensions, so the enquiry should show the stud and mating hole together.
For an accurate quotation, specify the thread size, nominal length, material requirement and surface finish, together with the intended mating component. Dimensions, inspection requirements and the exact material and finish combination must be agreed before order confirmation.
