Value Collection SHB-516-750-AS Hex Socket Cap Screw 5/16-18

Product Description

The VALUE COLLECTION SHB-516-750-AS is a hex socket cap screw designed for secure, high-torque fastening in mechanical, structural, and industrial assemblies. It features a 5/16-18 UNC thread and measures 3/4 inches in length under the head, with full threading along the entire shank. The fastener is manufactured from alloy steel and finished with a black oxide coating that provides mild corrosion resistance and a low-glare surface. The internal hex drive accepts a standard hex key or Allen wrench for installation in tight clearance areas where a conventional wrench cannot reach. This type of fastener is commonly installed by millwrights, maintenance technicians, and general contractors across a wide range of equipment and fixture applications.

This screw is suited for use in machinery assembly, equipment mounting, jigs and fixtures, and general maintenance and repair operations. The fully threaded 5/16-18 UNC configuration makes it appropriate for through-hole and threaded-insert applications where consistent clamping load along the full shank length is required. The black oxide finish makes it a common choice in applications where a non-reflective appearance is preferred alongside basic surface protection.

Key Features

• 5/16-18 UNC thread for compatibility with standard inch-series tapped holes
• 3/4 inch length under head with full threading along the entire shank
• Alloy steel construction provides higher tensile strength than plain carbon steel fasteners
• Black oxide finish delivers mild corrosion resistance and a low-reflectance surface
• Internal hex drive allows installation in recessed or confined locations

Compatibility

Designed as a standard inch-series hex socket cap screw for use in any application requiring a 5/16-18 UNC threaded fastener with a 3/4 inch length under head.

Installation Notes

Installation is performed using a hex key or Allen wrench sized to the internal drive of the screw head. Ensure the receiving hole is properly tapped to 5/16-18 UNC before installation. Apply appropriate thread-locking compound or pre-load torque per the equipment manufacturer's specifications and applicable fastener standards. Inspect threads for contamination or damage before assembly.
