Value Collection 211015PR Flat Socket Cap Screw 3-48

Product Description

The VALUE COLLECTION 211015PR is a flat socket cap screw designed for flush or countersunk fastening applications where a low-profile head is required. It features an 82-degree flat head with a 1/16-inch hex socket drive and is fully threaded along its 3/8-inch overall length. The thread size is 3-48 UNC. Manufactured from alloy steel with a black oxide finish, this screw offers good hardness and moderate corrosion resistance in indoor mechanical assemblies. It is typically installed by machinists, maintenance technicians, and industrial assembly professionals working with precision equipment and close-tolerance components.

This screw is suited for use in light-duty mechanical assemblies, jigs, fixtures, and equipment enclosures where a flush-mount fastener is required. The 3-48 UNC thread is a fine, small-diameter designation commonly found in instrument-grade and precision machined parts. The black oxide finish helps reduce light reflection and provides minimal surface protection. Sold individually with a minimum order quantity of 100 pieces, this fastener is intended for production or shop-stock purchasing rather than single-piece replacement.

Key Features

• 82-degree flat head profile for flush or countersunk installations
• 1/16-inch hex socket drive for precision torque application
• Fully threaded 3/8-inch overall length for maximum thread engagement
• 3-48 UNC thread standard for precision and instrument assembly use
• Alloy steel construction meets ASME/ANSI B18.3 and ASTM F835 fastener standards
• Black oxide finish reduces reflectivity and provides light surface protection

Compatibility

Designed as an OEM-style replacement or stock fastener for applications requiring a 3-48 UNC fully threaded flat socket cap screw conforming to ASME/ANSI B18.3 and ASTM F835 standards.

Installation Notes

Installation requires a 1/16-inch hex key or ball-end driver. Ensure the mating countersink angle matches the 82-degree head geometry before seating the fastener. Always drive to manufacturer-specified torque using a calibrated tool to avoid galling or head damage on small-diameter screws. Apply thread-locking compound if vibration resistance is required in the final assembly.
