Project Description

We supplied our industrial design customer these custom metric flange bolts in two different sizes, M12-1.75 X 35MM and M12 -1.75 X 45MM. Small batch of 100 pieces in each length was manufactured using our overseas production facility as a test run to allow our customer to test the parts in their mold application prior to a full production run. Due to the small quantities involved, the parts were machined rather than cold or hot headed. The machining process is much faster because it avoids lengthy and costly tooling and machinery set up, which would not be cost effective for a small run.

316 stainless steel material was used and the parts were made to a standard DIN 6921 specification. Once this small quantity is tested and approved the full production run will use cold heading manufacturing process to form the hex flange head.
