More About Part Number 167778

These 1/4-20 x 2 1/2" Thread Cutting Screws feature a Hex Washer Head with a Slotted Drive and are made from Steel. Thread cutting screws create mating threads by cutting into the material during installation, making them useful where a screw must form secure threads in preformed holes. Type F thread cutting screws are designed to cut machine-quality threads in sheet metal, castings, 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. A Slotted drive features a single straight groove that accommodates a flathead screwdriver for simple manual installation.
