Value Collection 211227PR Flat Socket Cap Screw 3/8-24

Product Description

The VALUE COLLECTION 211227PR is a flat socket cap screw designed for flush or countersunk fastening applications in mechanical assemblies. It features an 82-degree flat head with a 7/32-inch hex socket drive and is fully threaded along its 5/8-inch overall length. The 3/8-24 UNF thread specification makes it suitable for fine-thread applications where vibration resistance and precise load control are priorities. Constructed from alloy steel with a black oxide finish, this screw offers solid mechanical strength and moderate corrosion resistance in controlled environments. Licensed tradespeople and assembly technicians working in precision mechanical, automotive, or industrial applications will find this fastener meets ASME/ANSI B18.3 and ASTM F835 standards.

This flat socket cap screw is intended for applications requiring a low-profile, flush-mount head that sits at or below the surface of the mating material. The hex socket drive allows high torque input in tight spaces where a standard wrench cannot reach. It is well suited for machine components, fixtures, tooling plates, and precision mechanical assemblies where a countersunk profile is required. The fully threaded shank provides consistent thread engagement across the full length of the fastener.

Key Features

• 82-degree flat head seats flush in standard countersunk holes for a low-profile installation
• 7/32-inch hex socket drive accepts standard Allen or hex key tools for high-torque applications
• 3/8-24 UNF thread provides fine-pitch engagement for improved vibration resistance
• Fully threaded 5/8-inch overall length maximizes thread engagement in shallow blind or through holes
• Alloy steel construction meets ASME/ANSI B18.3 and ASTM F835 fastener standards
• Black oxide finish provides mild corrosion resistance and reduces light reflection on finished assemblies

Compatibility

Designed as a standard inch-series flat socket cap screw for use in countersunk applications requiring a 3/8-24 UNF thread and an 82-degree head angle per ASME/ANSI B18.3.

Installation Notes

Install using a calibrated 7/32-inch hex key or Allen driver; do not use worn or undersized keys, as this can damage the socket drive. Ensure the mating countersink is machined to an 82-degree included angle for full head seating. De-burr and clean the threaded hole before installation to prevent galling on the alloy steel threads. Follow applicable torque guidelines per ASME or job specification documentation for the 3/8-24 thread class in use.
