Support pins / diamond-shaped / chamfered flat head / press-fit pin / DIN 6321 (6321-8-16-B)

Workholding bolts DIN 6321 are inserted into bores for positioning, assisted by the flattened design (Form C) 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.
Types A and B can also be used as bearing surfaces, stops or as foot.
