More About Part Number 506129

These 1/4-20 x 3/8" Thread Cutting Screws feature a Hex Washer Head with an Unslotted 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. An Unslotted head contains no drive recess, making it useful in permanent or tamper-resistant fastening situations.
