Value Collection -36872-2 Flat Socket Cap Screw 5/16-24

Product Description

The VALUE COLLECTION -36872-2 is a 5/16-24 flat socket cap screw designed for flush or countersunk fastening applications in mechanical assemblies. The 82-degree flat head sits flush with or below the mating surface when installed in a properly countersunk hole. Driven by a 3/16-inch hex socket, the screw is fully threaded along its 3/4-inch overall length and manufactured from alloy steel with a black oxide finish that provides mild corrosion resistance and a low-reflectance appearance. This package contains 25 pieces.

These screws are used across industrial, mechanical, and fabrication applications where a low-profile or flush fastener is required. Common install scenarios include machine housings, jigs, fixtures, tooling plates, and precision assemblies where a protruding head would interfere with clearance or mating parts. The UNF (Unified National Fine) thread pitch makes them well-suited for applications requiring finer thread engagement and higher clamp load in thinner material sections.

Key Features

• 82-degree flat head profile seats flush in standard countersunk holes
• 3/16-inch hex socket drive for precise torque application with standard Allen keys or hex bits
• 5/16-24 UNF thread for fine-pitch engagement and strong clamping force
• Fully threaded along the entire 3/4-inch length for maximum thread engagement in shallow material
• Alloy steel construction meets ASME/ANSI B18.3 and ASTM F835 fastener standards
• Black oxide finish reduces light reflection and provides light surface protection

Compatibility

Designed as a standard ASME/ANSI B18.3 and ASTM F835 compliant flat socket cap screw suitable for any application requiring a 5/16-24 UNF fully threaded flat-head hex socket fastener in alloy steel.

Installation Notes

Installation is typically performed by machinists, millwrights, or mechanical assemblers using a 3/16-inch hex key or hex bit driver. The mating hole must be countersunk to 82 degrees to achieve proper head seating and flush surface results. Ensure the tapped hole thread class and material are compatible with a UNF 5/16-24 fastener before installation. Do not exceed the torque rating appropriate for the material and thread engagement depth.
