Value Collection 721510PR Flat Socket Cap Screw 3-48x5/16

Product Description

The VALUE COLLECTION 721510PR is a flat socket cap screw designed for precision fastening applications where a flush or countersunk head profile is required. Made from alloy steel with a black oxide finish, this screw delivers solid mechanical strength and moderate corrosion resistance in a compact form factor. It features a 1/16 inch hex socket drive and is fully threaded along its 5/16 inch overall length. The 3-48 UNC thread form makes it well-suited for small, tight-tolerance assemblies. Installation is performed with a hex key or Allen driver. This fastener conforms to ASME/ANSI B18.3 and ASTM F835 standards.

This flat socket cap screw is used in light mechanical assemblies, instrument panels, electronic enclosures, and other applications where a low-profile head must sit flush with or below the work surface. The small 3-48 thread size is common in precision machined components, fixtures, and equipment housings across industrial, electrical, and general fabrication trades. Its fully threaded shank maximizes thread engagement across short grip lengths, which is typical in thin-material assemblies.

Key Features

• Flat head profile seats flush or countersunk for low-clearance installations
• 1/16 inch hex socket drive for use with standard Allen keys or hex drivers
• Fully threaded 5/16 inch overall length maximizes thread engagement
• Alloy steel construction provides solid tensile strength for the fastener class
• Black oxide finish offers mild corrosion resistance and reduced light reflection
• Conforms to ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed as an OEM-style replacement or new-installation fastener for applications requiring a 3-48 UNC fully threaded flat socket cap screw with a 1/16 inch hex socket drive.

Installation Notes

Installation requires a 1/16 inch hex key or Allen driver sized to match the socket. Ensure the mating material is properly countersunk to the correct angle before driving to avoid head damage or improper seating. Follow applicable mechanical assembly standards and torque guidelines for size 3 alloy steel fasteners as specified by the governing design document or engineering standard. Minimum order quantity is 100 pieces.
