GN 6322 Workholding Bolt, with Ball Type Shoulder, Steel
Workholding bolts GN6322 are used for positioning in bores, with the ball-type shoulder facilitating the insertion into the bore.
The flattened design (Type C) helps to compensate tolerances in the spacing of two bores. Another application of this design is to fix parts to be positioned in one direction only.
