Meet the Thread Rolling Screws: an unslotted indented hex washer head fastener engineered for high-strength metal assemblies. Crafted from steel with a zinc finish and waxed coating, this drive is designed for smooth driving, excellent corrosion resistance, and durable performance. The Tri-Lobe drive provides positive engagement and reliable torque transfer, while the 5/16-18 x 2-1/4 size makes it a solid alternative to Taptite screws for a wide range of applications.

Key Features

  • Thread Rolling design: forms threads in the material, creating strong, burr-free threads and better fatigue resistance.
  • Unslotted Indented Hex Washer Head: flush seating with distributed load for secure fastening.
  • Tri-Lobe drive: ensures positive engagement and consistent torque transfer.
  • Material and Finish: steel with zinc plating and a wax coating for corrosion protection and lubricated installation.
  • Size: 5/16-18 x 2-1/4 inches (5/16-18 thread, 2-1/4" long).
  • Alternative to Taptite screws: a robust choice for achieving strong thread-forming performance in metal assemblies.

Benefits

  • High shear strength and vibration resistance thanks to the thread-rolling process.
  • Reduced risk of thread damage and fewer burrs compared with cut-thread fasteners.
  • Excellent corrosion protection with zinc finish and wax coating; lubricated threads ease driving and minimize seizing.
  • Easy installation with compatible tools and reliable drive engagement.

Applications

Ideal for metal enclosures, automotive components, machinery, electrical panels, and other metal-to-metal assemblies.
