Value Collection 721217PR Flat Socket Cap Screw 3/8-24

Product Description

The VALUE COLLECTION 721217PR is a flat socket cap screw designed for precision fastening applications where a flush or countersunk profile is required. Manufactured from alloy steel with a black oxide finish, this fastener measures 3/8-24 (UNF) x 2-1/4 inches overall length and is partially threaded along its shank. The 82-degree flat head seats into a standard countersunk hole, and the 7/32-inch hex socket drive accepts a standard hex key for installation and removal. This screw is commonly installed by machinists, maintenance technicians, and mechanical assembly professionals working in industrial and commercial environments.

This flat socket cap screw is suited for use in machine assemblies, fixture builds, and mechanical enclosures where a low-profile, flush-mount fastener is required. The partial threading provides a smooth shank section useful in applications requiring a bearing surface or precise hole alignment. The alloy steel construction offers strength appropriate for medium-to-high load fastening tasks. The black oxide finish provides moderate corrosion resistance and reduces light reflection in precision tooling and assembly contexts.

Key Features

• 82-degree flat head seats flush in standard countersunk holes
• 7/32-inch hex socket drive for precise torque application with a standard hex key
• Partially threaded shank allows use as a shoulder-style fastener where a smooth bearing surface is needed
• Alloy steel construction provides high tensile strength for demanding mechanical assemblies
• Black oxide finish offers moderate corrosion resistance and a low-reflectance appearance
• Conforms to ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard UNF 3/8-24 flat socket cap screw suitable for use in any application requiring an ASME/ANSI B18.3 or ASTM F835 compliant countersunk hex-drive fastener at this thread size and length.

Installation Notes

Install using a calibrated 7/32-inch hex key or socket driver. Ensure the mating countersink is machined to the correct 82-degree included angle for full head seating. Power down or de-energize any equipment before fastener replacement in live assemblies. Follow applicable torque specifications for 3/8-24 alloy steel fasteners per your project engineering requirements or relevant ASME standards.
