These are custom 6-lobe socket cap screws made domestically using 4037 alloy steel material. Strength was absolutely critical to our customer and the parts were heat treated to 39-43 hrc. In the absence of an available drawing for this part we had to work off samples our customer provided for all dimensional attributes. After confirming the material, strength, and dimensional requirements we had 1,000 pcs produced for our customer with a lead time of approximately 12 weeks from order confirmation. Heat treat and material certs were included with the parts.
