Value Collection 837239PR Hex Socket Cap Screw 5/16-24 Unf

Product Description

The VALUE COLLECTION 837239PR is a hex socket cap screw designed for fastening applications that require a strong, recessed-drive connection. Manufactured from alloy steel with a zinc-plated finish, this fastener meets ASTM B695 standards for corrosion resistance. The screw features a 5/16-24 UNF thread size, a 1-3/4 inch length under head, and accepts a 1/4 inch hex drive. Partial threading along the shank allows for precise clamping force without thread engagement through the full grip length. Suitable for mechanical assemblies, equipment fabrication, and general industrial fastening tasks performed by machinists, millwrights, maintenance technicians, and fabricators.

This cap screw is used in applications where a flush or low-profile fastener head is required and access is limited to a hex key or Allen driver. The 5/16-24 UNF fine-thread specification provides tighter thread engagement and greater resistance to loosening under vibration compared to coarse-thread equivalents. Typical install scenarios include mounting brackets, machinery guards, precision equipment housings, and structural assemblies in both light and heavy industrial environments. The zinc plating provides baseline corrosion protection for indoor and moderately exposed service conditions.

Key Features

• 5/16-24 UNF fine thread for secure engagement and vibration resistance
• 1-3/4 inch length under head with partial threading for controlled grip length
• 1/4 inch hex socket drive for use with standard Allen keys or hex drivers
• Alloy steel construction for high tensile strength in demanding fastening applications
• Zinc-plated finish meeting ASTM B695 for corrosion protection

Compatibility

Designed as an OEM-style replacement or standard-fit fastener for any assembly requiring a 5/16-24 UNF hex socket cap screw with a 1/4 inch drive and 1-3/4 inch length under head.

Installation Notes

Installation is performed using a 1/4 inch hex key or Allen driver. Ensure mating threads are clean and free of debris before installation. Apply appropriate thread lubricant or threadlocker as required by the assembly specification. Always follow applicable torque guidelines specified in the original equipment documentation or relevant industry standards.
