Closed Seam Hollow Dowels

SITUATION

A leading automotive assembly manufacturer required a dual-purpose fastener to replace the more expensive alignment part they had been using. The fastener needed to center and align multiple pieces, while allowing fluid to pass through the fastening joint.

SOLUTION

Driv-Lok Inc.’s ENGINOMICS ® Team resolved this issue for the customer by developing the Closed Seam Hollow Dowel. This part replaced expensive seamless hollow dowels and other alignment-type products that the customer had been using. By utilizing Closed Seam Hollow Dowels, the customer was able to align multiple pieces with easy insertion, improve throughput, and maintain a leak-free joint. They also saved money, as production of Closed Seam Hollow Dowels involves minimal scrap and is more efficient than conventional methods of machining seamless hollow dowels.
