More About Part Number 578591

These #12 x 1/2" Thread Forming Screws for Plastics 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. These Thread Forming Screws are designed specifically for plastic, forming durable mating threads while helping reduce stress in the material. 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.
