More About Part Number 158963

These 1/4-20 x 1/2" 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 23 thread cutting screws feature a broad cutting slot and are commonly used for cutting threads in softer metals 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.
