Value Collection 88546759 Hex Socket Cap Screw 5/16-18

Product Description

The VALUE COLLECTION 88546759 is a partially threaded hex socket cap screw designed for secure mechanical fastening in industrial, commercial, and trade applications. Sized at 5/16-18 UNC with a 1-1/2 inch length under head, it accepts a 1/4 inch hex drive for precise torque application using a standard Allen key or hex bit. The fastener is manufactured from alloy steel with a black oxide finish, providing improved corrosion resistance and reduced surface reflectivity. This screw ships in a package of 13 units, making it well suited for small-batch repair work, equipment assembly, or stocking a job kit.

This screw is appropriate for residential and commercial mechanical assemblies where a recessed hex drive fastener is required. Common applications include HVAC equipment panels and brackets, electrical enclosures, pump housings, and general structural assemblies requiring a higher-strength fastener than a standard machine screw. The black oxide coating makes it a practical choice where a low-profile, non-reflective finish is preferred. Installed by maintenance technicians, millwrights, HVAC mechanics, and plumbers during equipment service or new installation work.

Key Features

• 5/16-18 UNC thread size for broad compatibility with standard tapped holes
• 1-1/2 inch length under head with partial threading for clamping strength
• 1/4 inch hex socket drive for use with standard Allen keys or hex bits
• Alloy steel construction for higher tensile strength than standard carbon steel fasteners
• Black oxide finish for mild corrosion resistance and reduced surface glare
• Package of 13 units suitable for small repairs or job-kit restocking

Compatibility

Designed as a standard 5/16-18 UNC hex socket cap screw suitable for any tapped hole or threaded insert conforming to UNC 5/16-18 specifications across a wide range of mechanical assemblies.

Installation Notes

Install using a 1/4 inch hex key or hex bit driver; a torque wrench with a hex bit socket is recommended for controlled fastening in structural applications. Always ensure the mating threaded hole is clean and free of debris before installation. De-energize and lock out any electrical or mechanical equipment before replacing fasteners on live systems. Follow applicable codes and equipment manufacturer specifications for torque requirements.
