Engineered for strength and a clean, professional finish, this Machine Screw features an unslotted indented hex washer head, steel construction, and a durable black oxide coating. Sized 5/16-18 x 1, it's ideal for precise, high-torque fastening in tapped holes or with nuts.
- Drive Type: Internal hex (Allen) drive for a slotted-free, high-torque engagement
- Head Style: Indented hex washer head provides a flush, low-profile look and distributes load over a larger area
- Material & Finish: Steel with a black oxide finish for corrosion resistance and a sleek appearance
- Thread Size & Length: 5/16-18 UNC, 1 inch long
- Applications: Great for equipment enclosures, control panels, and assemblies where a secure, neat fastener is required
To install, use the appropriate Allen (hex) drive with compatible taps or nuts. Avoid over-tightening to preserve thread integrity.
