These are custom Monel 400 socket head cap screws measuring 5/8-11 by 3-1/2" in length.  Domestically produced with a lead time of just 4 days, the 4 pieces we had manufactured incorporated coarse cut thread and a broached socket head drive.  Material certs and a certificate of conformance was provided with the parts per our customer's request.

Our relationships with factories all over the United States and abroad based on decades of custom hardware & fastener production history, in combination with the flexibility of blanket purchase arrangements, allows us to fully cater to the customer’s hardware specification and procurement requirements.
