Value Collection 79887832 Hex Socket Cap Screw 5/16-18 Unc

Product Description

The VALUE COLLECTION 79887832 is a 5/16-18 UNC hex socket cap screw designed for general mechanical fastening applications across industrial, commercial, and trade environments. The screw measures 2-1/2 inches under the head and uses a 1/4 inch hex drive for installation with a standard hex key or Allen wrench. It is constructed from alloy steel with a black oxide finish, providing moderate corrosion resistance and a clean appearance. This fastener is partially threaded and is sold in a package of 13. Machinists, millwrights, HVAC installers, and general tradespeople commonly use socket cap screws like this in equipment assembly, panel mounting, and structural fastening tasks.

This screw is suited for residential and commercial mechanical assemblies where a low-profile, high-strength threaded fastener is required. The 5/16-18 UNC coarse thread is a widely used standard size compatible with tapped holes and threaded inserts found in a broad range of equipment, brackets, and structural components. The black oxide finish makes it a common choice where light rust resistance and a non-reflective surface are acceptable. Typical applications include equipment frames, motor mounts, HVAC component brackets, and general fabrication work.

Key Features

• 5/16-18 UNC coarse thread for broad compatibility with standard tapped holes and inserts
• 2-1/2 inch length under head accommodates medium-depth fastening applications
• 1/4 inch hex drive accepts standard hex keys and Allen wrenches
• Alloy steel construction provides high tensile strength for mechanical assemblies
• Black oxide finish offers light corrosion resistance and a non-reflective surface
• Partially threaded shank helps locate and align mating components before full engagement

Compatibility

Designed as a standard 5/16-18 UNC socket cap screw for use in any application requiring a 1/4 inch hex drive fastener of this thread size and length.

Installation Notes

Install using a 1/4 inch hex key or T-handle Allen wrench; an impact driver with the appropriate hex bit may also be used in production settings. De-energize or lock out any equipment before fastening components to moving or live assemblies per standard OSHA lockout/tagout procedures. Apply thread-locking compound if vibration is a concern in the installation environment. Do not exceed the torque rating of the tapped material when tightening.
