More About Part Number 556921

These 1/4-20 x 2" Self-Drilling Screws feature a Hex Washer Head with an Unslotted Drive and are made from Steel. Self-drilling screws combine a drill-point tip with threaded fastening capability, allowing them to drill, tap, and fasten in a single operation. 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.
