Value Collection 307106PR Hex Socket Cap Screw 5/16-18 Unc

Product Description

The VALUE COLLECTION 307106PR is a fully threaded hex socket cap screw designed for secure mechanical fastening in industrial, commercial, and trade applications. Sized at 5/16-18 UNC with a 3/4-inch length under head, this screw is driven by a 7/32-inch hex (Allen) key. It is manufactured from alloy steel with a black oxide coating for added corrosion resistance and reduced light reflection. This fastener meets ASTM A574 standards, making it appropriate for high-strength applications where a reliable clamped joint is required. It is commonly installed by millwrights, pipefitters, HVAC technicians, electricians, and general maintenance professionals.

This cap screw is suited for a wide range of mechanical assemblies, equipment mounting, and structural fastening tasks across residential, commercial, and light industrial settings. Its fully threaded shank provides maximum thread engagement in shallow through-hole or tapped-hole applications. The black oxide finish makes it a common choice in environments where a low-profile, non-reflective appearance is preferred alongside moderate corrosion protection.

Key Features

• 5/16-18 UNC thread size for broad compatibility with standard tapped holes
• 3/4-inch length under head for precise fitment in shallow assemblies
• Fully threaded shank maximizes thread engagement across the entire shaft
• 7/32-inch hex drive for use with standard Allen wrenches and hex bit drivers
• Alloy steel construction provides high tensile strength per ASTM A574
• Black oxide coating offers mild corrosion resistance and a non-reflective finish

Compatibility

Designed as an OEM-style replacement or standard-fit fastener for any application requiring a 5/16-18 UNC hex socket cap screw with a 3/4-inch length under head and 7/32-inch hex drive, conforming to ASTM A574.

Installation Notes

Installation should be performed by a qualified technician using the correct 7/32-inch hex key or Allen bit driver. Ensure the mating tapped hole is clean and free of debris before threading the fastener. Do not overtighten, as alloy steel cap screws installed into softer base materials may strip threads if torque is not managed appropriately. Always de-energize or shut down equipment before accessing fastened assemblies in electrical or mechanical systems.
