Value Collection 011143P Hex Socket Cap Screw 1/4-20 Unc

Product Description

The VALUE COLLECTION 011143P is a hex socket cap screw designed for secure fastening in mechanical, industrial, and trade applications. Sized at 1/4-20 UNC with a 3/8 inch length under head, this screw is fully threaded and driven by a 3/16 inch hex key. The alloy steel construction delivers high tensile strength, and the black oxide coating provides corrosion resistance and a clean, low-glare finish. This fastener meets ASME/ANSI B18.3 and ASTM A574 standards, making it suitable for demanding service environments where dimensional accuracy and material performance are required.

This fastener is used across a wide range of mechanical assemblies, equipment maintenance, and structural applications. Common install scenarios include machine frames, HVAC equipment panels, pump housings, electrical enclosures, and general industrial hardware. The 1/4-20 UNC thread is one of the most common unified coarse thread sizes in North American trade work, making this screw a standard replacement and stock item for maintenance technicians and fabricators alike.
