We supplied these custom 12 point flange bolts to our automotive customer at 5,000 pieces per size, with size ranging from 12.6MM shoulder diameter X 1.70" to 12.6MM shoulder diameter X 3.2". 4140 alloy steel material was used for the production with heat treatment to reach 39-45HRC hardness. Black oxide finish was the last step in the production process. 3/8-16 internal thread was tapped on all size configurations to reach a minimum of 18MM in full thread depth.
These custom trim aluminum diecast fittings for our lighting fixture customer were manufactured using ADC12 Aluminum Alloy material with plain finish. Overall diameter measured 5.75" and the inside opening diameter measured 2.55". 2,500 pieces were produced in the first production run and a small partial was provided prior to the full balance. Annual blanket purchase agreements are ideal for this type of part due to the space and cash output required to bring in the full amount in one shipment - we would instead spread out the annual usage over 12 months and invoice as parts are shipped out.
We supplied our customer that manufactures fire pump equipment with these custom 17-4ph precision dowel pins using 100% domestic production with DFARS compliant raw material and full certs - material certs, heat treat certs, and a certificate of conformance. The pins were produced to a diameter of .1249-.1251" and overall length of .670-.675" with equal spherical radii on both sides. Parts went through heat treatment to achieve the Rc36 hardness minimum requirement.
