For all those who are concerned about the quality and cost of mass-produced parts for automobiles, robots, precision equipment, etc.

This example is a fastening bolt (hollow pin) used as an automotive part. It is characterized by the fact that it has a brim, a hollow hole in the head, and a stepped shaft. The inside diameter is a hexagonal hole.

The bolt used to include a cutting process, but now the entire process is done by a parts former, resulting in significant cost reductions and a shorter manufacturing lead time.

Arai Parts Co., Ltd. which operates the "Cold Forging/VA/VE Center" has abundant experience in manufacturing hollow pins with a brim like this product. If you are having trouble with mass production of pins and bolts, please contact Alai Parts Co.
