Value Collection 581368PR Hex Socket Cap Screw 1/4-20 Unc

Product Description

The VALUE COLLECTION 581368PR is a hex socket cap screw designed for high-strength fastening in mechanical and industrial assemblies. It features a 1/4-20 UNC thread size and a 9/16-inch length under head, with full threading along the shank. The 3/16-inch hex drive accepts a standard Allen key or hex bit driver. Constructed from alloy steel with a black oxide finish, this fastener delivers solid tensile strength and moderate corrosion resistance in light-duty service environments. It meets ASME/ANSI B18.3 and ASTM A574 standards, making it suitable for precision mechanical work where dimensional accuracy matters.

This screw is used across a wide range of applications including machine assembly, equipment maintenance, HVAC component mounting, electrical panel fabrication, and general trade work wherever a low-profile, high-strength cap screw is required. The socket drive design allows installation in confined or recessed spaces where a standard hex head wrench cannot reach. It is well-suited for use in steel, aluminum, and other metal substrates in both residential and light commercial settings.

Key Features

• 1/4-20 UNC thread form for compatibility with standard inch-series tapped holes
• 9/16-inch length under head, fully threaded shank for maximum thread engagement
• 3/16-inch hex socket drive for Allen key or hex bit installation
• Alloy steel construction meets ASTM A574 mechanical property requirements
• Black oxide finish provides a non-reflective surface and light rust inhibition
• Conforms to ASME/ANSI B18.3 dimensional standard for socket cap screws

Compatibility

Designed as an OEM-style replacement or stock fastener for any application requiring a 1/4-20 UNC hex socket cap screw with a 9/16-inch length under head and ASME/ANSI B18.3 compliance.

Installation Notes

Installation is performed with a 3/16-inch hex key or hex bit driver. Power down or de-energize any equipment before disassembling fastened assemblies. Apply thread-locking compound or torque to the fastener per the equipment manufacturer's specifications for the assembly being serviced. Always confirm the tapped hole thread form and depth before installation to avoid cross-threading or insufficient engagement.
