These custom low profile socket head screws with a  6-lobe (torx) drive were manufactured domestically using 302 stainless steel material with a commercial passivated plain finish.  5,000 pieces of two sizes were produced: M10 - 1.5M X 65MM with a T-45 drive size and M8 - 1.25M X 65MM with a T-30 drive size.  26-30MM of thread was incorporated on the larger version and 22-25MM on the smaller diameter part.  The low profile & 6-lobe drive combination is relatively tricky, especially for these larger diameters as additional controls in tooling are required to avoid flowering on the outside profile of the head.
