Value Collection R40682206 Hex Socket Cap Screw 3/8-16

Product Description

The VALUE COLLECTION R40682206 is a hex socket cap screw designed for fastening applications that require a recessed Allen-style drive and corrosion-resistant construction. Featuring a 3/8-16 UNC thread and a 3.5 inch length under head, this fastener is driven with a 5/16 inch hex key. Constructed from 18-8 stainless steel, it provides solid resistance to rust and oxidation in wet, outdoor, or chemically exposed environments. Machinists, maintenance technicians, fabricators, and mechanical contractors use this type of fastener where a low-profile head and internal hex drive are required.

This screw is suited for general mechanical assembly, equipment maintenance, structural fastening, and machine-component work across industrial, commercial, and trade settings. The 3/8-16 UNC coarse thread is a widely used standard size, making this screw compatible with a broad range of pre-tapped holes, inserts, and nuts in fabricated steel, aluminum, and plastic assemblies. It is a practical choice wherever corrosion resistance and drive recess protection are priorities.

Key Features

• 3/8-16 UNC coarse thread for broad compatibility with standard tapped holes and hardware
• 3.5 inch length under head provides generous grip length for thicker assemblies
• 5/16 inch internal hex drive accepts standard Allen or hex key sets
• 18-8 stainless steel construction resists corrosion in wet and chemically active environments
• Low-profile socket cap head keeps a clean profile in recessed or countersunk applications

Compatibility

Designed as a standard UNC hex socket cap screw for use in any application requiring a 3/8-16 coarse thread fastener with an internal hex drive.

Installation Notes

Install using a properly sized 5/16 inch hex key or Allen wrench to avoid stripping the socket drive. Ensure the mating tapped hole or nut is clean and free of debris before installation. When installing in stainless steel assemblies, apply an appropriate anti-seize compound to prevent galling. Follow applicable torque standards for 3/8-16 fasteners per the applicable mechanical or structural specification for the job.
