Value Collection R57001062 Hex Socket Cap Screw 3/8-24

Product Description

The VALUE COLLECTION R57001062 is a hex socket cap screw designed for applications requiring a secure, recessed-drive fastener. Threaded to the 3/8-24 UNF specification, this fine-thread screw seats into a 5/16-inch hex (Allen) drive socket and measures 3.5 inches under the head. It is constructed from 18-8 stainless steel with a bright, uncoated finish, offering solid corrosion resistance in general mechanical, plumbing, and HVAC bracket assemblies. Machinists, millwrights, and trade technicians install this type of fastener where vibration resistance and a flush or countersunk head profile are required.

This screw is suited for use in light industrial and commercial equipment assemblies, maintenance and repair operations, and field fabrication work. The 3/8-24 UNF fine-thread pitch provides higher thread engagement per inch compared to coarse-thread equivalents, making it a common choice in metal-to-metal fastening where load distribution and pullout resistance matter. Typical applications include equipment panel mounting, mechanical supports, and structural bracketing across HVAC, plumbing, and electrical trade work.

Key Features

• 3/8-24 UNF fine-thread specification for high thread engagement in metal fastening
• 3.5 inches length under head for deep through-hole or threaded insert applications
• 5/16-inch hex socket drive compatible with standard Allen wrenches and hex bit drivers
• 18-8 stainless steel construction provides corrosion resistance in wet or outdoor environments
• Bright uncoated finish maintains dimensional accuracy for precision thread fit

Compatibility

Designed as a standard UNF hex socket cap screw for use in any application requiring a 3/8-24 fine-thread fastener with a 5/16-inch hex drive and 3.5-inch length under head.

Installation Notes

Installation is performed with a 5/16-inch hex key or Allen bit driver. Ensure the receiving threads are clean and free of debris before driving. Do not overtighten stainless steel fasteners in stainless threaded holes, as galling can occur; applying an appropriate anti-seize compound is standard practice. Power down or de-energize any equipment before performing fastener service on live assemblies.
