More About Part Number 328630

These #12 x 3 1/2" Self-Tapping Screws feature a Hex Washer Head with an Unslotted Drive and are made from Steel. Self-tapping screws are designed to create mating threads during installation, making them useful for fastening into preformed holes in sheet metal, plastic, and similar materials. Type A self-tapping screws feature coarse threads and a gimlet-style point, making them useful in thin sheet metal, wood, 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.
