Quality Roll Threading of a Roll Threaded Screw for the Recreational Vehicle Industry

Family-owned and operated Keystone Threaded Products, we have earned our reputation for handling large volume production. We're also adept at providing the solutions and meeting the challenges provided by our customers, whether it's a tight timeline or an unusual part.

A client in the recreational vehicle industry required 15,000 roll-threaded screws with 2G ACME threads in the center of the part with "blanks" on either end, rather than the typical end-to-end thread placement. We readily accepted the blanket order, then performed the precision roll threading and created the partial threads. We cut the parts to length, and chamfered them. The C1215 plain finish steel parts were outsourced for zinc plating to ASTM B633 SC1 Type VI. We ensured the screws met the customer's specific yet variable tolerances by conducting in-process testing tolerances as well as a final inspection.
