Value Collection -36872-3 Flat Socket Cap Screw 5/16-24

Product Description

The VALUE COLLECTION -36872-3 is a flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. Featuring an 82-degree flat head and a 3/16-inch hex socket drive, this screw accepts a standard hex key for installation and removal. Manufactured from alloy steel with a black oxide finish, it provides moderate corrosion resistance and a low-reflectance appearance suitable for industrial and mechanical assemblies. The 5/16-24 UNF thread and 1-inch overall length make it a common choice for precision fastening in tight-tolerance work. The screw is fully threaded along its 1-inch length. Package quantity is 25 pieces.

This flat socket cap screw is used wherever a recessed, low-profile fastener head is required. Typical applications include machine components, jigs and fixtures, tooling plates, enclosures, and mechanical assemblies where the fastener head must sit flush with or below the mating surface. The 5/16-24 UNF fine thread is well suited to applications requiring precise clamping force or use in thinner materials. It is commonly installed by machinists, maintenance technicians, and mechanical assemblers in light industrial and manufacturing environments.

Key Features

• 82-degree flat head seats flush in standard countersunk holes per ASME/ANSI B18.3
• 3/16-inch hex socket drive for use with standard hex keys or socket-drive tooling
• 5/16-24 UNF fine thread for precise clamping and compatibility with fine-thread tapped holes
• Fully threaded 1-inch overall length maximizes thread engagement in shallow or thin assemblies
• Alloy steel construction meets ASTM F835 mechanical requirements
• Black oxide finish provides moderate corrosion resistance and reduces surface reflectivity

Compatibility

Designed as a standard replacement or stock fastener for 5/16-24 UNF countersunk hex socket applications conforming to ASME/ANSI B18.3 and ASTM F835.

Installation Notes

Installation requires a 3/16-inch hex key or matching bit driver. The mating hole should be countersunk to 82 degrees to achieve proper head seating. Verify that the tapped hole or nut is cut to UNF thread specification before driving. Consult applicable mechanical or structural codes for torque requirements specific to your assembly and material.
