These are custom captive stainless screws we supplied to our construction customer, who refers to them as “Gripper Screws”. Production was done domestically in the USA at approximately 5,000 pieces and a lead time of 6-8 weeks. The multi-step flat head was made using a cold heading process and the 10-32 thread was rolled at 0.2″ in length. The diameter of the unthreaded shoulder was set at 0.14″ +/-.015.
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.
