Converting Stainless Steel Fasteners from Screw Machine to Cold Headed for the Automotive & Electronics Industry

An international automotive company approached Jeffrey-Jae Company, Inc. for a cost saving alternative on a high-volume part. Jeffrey-Jae was able to convert these stainless steel fasteners from screw machine to cold headed for an automotive computer assembly application. Utilizing precision cold heading and a secondary shaving operation, Jeffrey-Jae was able to create a custom fastener with a head size of 5.7mm with the option of either a hex head or flat screwdriver slot. The 14.05mm long, .006oz steel fasteners were made from 302 stainless steel and had a tightest tolerance within .005". Each fastener came pre-assembled with a SEMS spring washer and featured a shank with a smaller than nominal thread diameter, allowing for easier assembly.

Most importantly, our processes not only saved the client 70% over screw machining but also gave them the option to create fasteners with any head type and thread up to 4.5" in length.
