Value Collection R57001057 Hex Socket Cap Screw 3/8-16

Product Description

The VALUE COLLECTION R57001057 is a hex socket cap screw designed for secure fastening in applications where a flush or recessed drive is required. Sized at 3/8-16 UNC thread with a 5-1/2 inch length under head, it accepts a 5/16 inch hex key drive. Constructed from 18-8 stainless steel with a bright uncoated finish, it offers corrosion resistance suitable for general industrial, mechanical, and trade service environments. This fastener is installed by mechanics, maintenance technicians, pipefitters, and other trade professionals who need a reliable, corrosion-resistant socket cap screw for structural or equipment assembly work.

This screw is suited for use in residential and commercial maintenance, equipment assembly, HVAC equipment mounting, plumbing fixture attachment, and general mechanical fabrication. The 3/8-16 UNC coarse thread provides strong thread engagement in steel, aluminum, and other common base materials. The 18-8 stainless steel construction makes it appropriate for damp or mildly corrosive environments where carbon steel fasteners would be unsuitable.

Key Features

• 3/8-16 UNC coarse thread for broad compatibility with standard tapped holes
• 5-1/2 inch length under head for deep fastening applications
• 5/16 inch hex socket drive for use with standard Allen keys or hex bit drivers
• 18-8 stainless steel construction resists corrosion in damp and mildly corrosive environments
• Bright uncoated finish maintains dimensional accuracy and consistent thread fit

Compatibility

Designed as a standard 3/8-16 UNC hex socket cap screw suitable for use wherever this thread size and drive type are specified in equipment assembly, mounting, or structural fastening applications.

Installation Notes

Install using a 5/16 inch hex key or Allen-style socket bit. Ensure the tapped hole or mating nut is clean and free of debris before threading to avoid cross-threading. Torque to the specification required by the equipment or structural drawing being serviced. De-energize or isolate any equipment before accessing fastener locations on live mechanical or electrical assemblies.
