Value Collection 211103PR Flat Socket Cap Screw 1/4-20

Product Description

The VALUE COLLECTION 211103PR is a flat socket cap screw designed for flush or countersunk fastening applications in metal assemblies and mechanical components. It features a 82-degree flat head driven by a 5/32-inch hex socket, allowing it to sit flush with or below the surface of the workpiece. The fastener is fully threaded in 1/4-20 UNC and measures 3/8 inches in overall length. Manufactured from alloy steel with a black oxide finish, it offers improved corrosion resistance compared to bare steel while maintaining a low-profile appearance. Machinists, maintenance technicians, and fabricators commonly install this type of fastener in precision assemblies, fixtures, and industrial equipment.

This flat socket cap screw is suited for light-duty to medium-duty fastening tasks where a countersunk, flush-mount installation is required. Its 1/4-20 UNC thread form makes it a common choice in general mechanical assemblies, machine guards, tooling plates, and enclosures. The black oxide finish is appropriate for indoor or low-moisture environments where mild surface protection is acceptable. This item is sold individually but carries a minimum order quantity of 100 units, making it appropriate for production, maintenance stock, or shop inventory replenishment.

Key Features

• 82-degree flat head for flush or countersunk seating in standard countersunk holes
• 5/32-inch hex socket drive for precise torque application with standard hex keys
• Fully threaded 1/4-20 UNC shank for maximum thread engagement across the full fastener length
• Alloy steel construction for high tensile strength in mechanical fastening applications
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Meets ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard 1/4-20 UNC flat socket cap screw per ASME/ANSI B18.3, compatible with any tapped 1/4-20 countersunk hole accepting an 82-degree flat head fastener in industrial, mechanical, or fabrication assemblies.

Installation Notes

Installation is performed with a 5/32-inch hex key or Allen driver. Ensure the mating countersink angle is machined to 82 degrees for proper head seating. Verify thread engagement depth in the tapped hole meets application load requirements before torquing. Follow applicable mechanical assembly standards and use calibrated torque tools to avoid stripping the alloy steel threads.
