More About Part Number 178606

These 5/16-18 x 1 1/2" Machine Screws feature a Hex Washer Head with an Unslotted Drive and are made from Steel. Machine screws are uniform-diameter threaded fasteners commonly used with tapped holes or nuts in machinery, electronics, and general assembly applications. 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.
