More About Part Number 396921

These 1/4-20 x 3/4" Thread Forming Screws feature a Hex Washer Head with a Slotted Drive and are made from 18-8 Stainless Steel. Thread forming screws create mating threads by displacing material rather than cutting it, making them useful in softer materials where strong thread engagement is desired. Taptite style thread forming screws are designed to reduce driving torque while creating strong mating threads in ductile metals and similar materials. They feature a Plain Finish, meaning no additional surface coating has been applied; this is commonly used where the part will be painted, plated, or used in controlled indoor environments. The Hex Washer Head incorporates a built-in washer flange beneath the head, increasing bearing surface and improving load distribution while remaining compatible with standard hex drivers. A Slotted drive features a single straight groove that accommodates a flathead screwdriver for simple manual installation.
