More About Part Number 423222

These 1/4-20 x 1/2" Thread Forming Screws feature a Hex Washer Head with an Unslotted Drive and are made from 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 Zinc Finish, which provides reliable corrosion protection for general-purpose indoor and light outdoor applications while remaining a cost-effective choice for everyday fastening needs. 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. An Unslotted head contains no drive recess, making it useful in permanent or tamper-resistant fastening situations.
