Thread Rolling Screws – Slotted Indented Hex Washer Head, Tri-Lobe Drive, 1/4-20 x 3/8

Engineered for secure, high-strength fastening in metal assemblies, these Thread Rolling Screws deliver dependable performance. Featuring a slotted indented hex washer head, zinc-coated steel, and a waxed finish, plus a Tri-Lobe drive, they provide precise engagement, easy driving, and strong thread formation. Sized at 1/4-20 UNC with a 3/8 inch length, they serve as a practical alternative to traditional Taptite screws.

Overview

Thread rolling screws form their own strong, consistent threads by displacing metal rather than cutting it. This thread-rolling action yields higher pull-out resistance and smoother driving. The slotted indented hex washer head seats flush, while the Tri-Lobe drive reduces cam-out for reliable installation, even in challenging assemblies.

Key Features

• Thread Rolling Action: Form durable, interference-free threads in metal for robust holding power.
• Head & Drive: Slotted indented hex washer head with Tri-Lobe drive for secure seating and improved torque.
