Value Collection 36823 Flat Socket Cap Screw 5/16-18 X 3/4 in

Product Description

The VALUE COLLECTION 36823 is a flat socket cap screw designed for flush or countersunk fastening applications in mechanical assemblies, fixtures, and equipment. The 82-degree flat head seats fully into a countersunk hole, leaving a smooth surface at or below the workpiece. Driven by a 3/16-inch hex socket, this fastener is sized at 5/16-18 UNC x 3/4 inches overall length and is fully threaded. Constructed from alloy steel with a black oxide finish, it offers solid mechanical strength and moderate corrosion resistance suitable for indoor and light-duty industrial environments. Licensed trade professionals and maintenance technicians working on equipment panels, structural brackets, or machinery housings are the primary installers.

This screw is well-suited for use in HVAC equipment enclosures, electrical panel mounting, plumbing fixture hardware, and general mechanical assembly where a flush fastener profile is required. The 5/16-18 UNC thread standard ensures compatibility with standard tapped holes and threaded inserts of the same size. Fully threaded construction provides maximum thread engagement across the entire grip length, which is particularly useful in shallow-boss or thin-material applications. Minimum order quantity is 25 pieces.

Key Features

• 82-degree flat head profile for flush or sub-flush countersunk installations
• 3/16-inch hex socket drive for reliable torque application with standard Allen keys or hex bits
• Fully threaded 5/16-18 UNC shank maximizes thread engagement in thin or shallow boss materials
• Alloy steel construction provides high tensile strength for structural and mechanical fastening
• Black oxide finish delivers moderate corrosion resistance and reduced light reflection in finished assemblies
• Conforms to ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard UNC replacement or new-install flat socket cap screw for any application requiring a 5/16-18 threaded, 82-degree countersunk fastener per ASME/ANSI B18.3 and ASTM F835 specifications.

Installation Notes

Install using a 3/16-inch hex key or hex socket bit; ensure the countersunk hole is machined to 82 degrees for proper head seating. De-energize and lock out any equipment before fastener service work on live panels or enclosures. Verify thread engagement depth meets structural requirements before final torque. Do not reuse fasteners that show signs of thread deformation or head socket damage.
