Value Collection MP63878 Flat Socket Cap Screw 3/8-16

Product Description

The VALUE COLLECTION MP63878 is a flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. Featuring an 82-degree flat head and a 7/32-inch hex socket drive, this screw is driven with a standard hex key or Allen wrench. The 3/8-16 UNC thread and 1-1/2-inch overall length make it suitable for medium-load structural and mechanical assemblies. Constructed from 18-8 stainless steel, the fastener offers good corrosion resistance in mildly corrosive and outdoor environments. This screw is used by machinists, pipefitters, and general maintenance technicians in both light industrial and commercial trade applications.

This flat socket cap screw is appropriate for use in metal fabrication, equipment assembly, plumbing fixture mounting, and general mechanical maintenance where a flush-mount fastener is required. The 3/8-16 UNC thread is a widely used coarse-thread standard, making this screw compatible with a broad range of tapped holes in steel, aluminum, and similar substrates. The 18-8 stainless steel construction suits environments where mild corrosion resistance is a priority, such as wet mechanical rooms or outdoor equipment panels.

Key Features

• 82-degree flat head sits flush or countersunk with the mating surface
• 7/32-inch hex socket drive for use with standard Allen or hex keys
• 3/8-16 UNC coarse-thread standard for wide compatibility with tapped holes
• 18-8 stainless steel construction provides corrosion resistance in moist or mildly corrosive environments
• 1-1/2-inch overall length suits medium-depth fastening applications

Compatibility

Designed as a standard UNC coarse-thread flat socket cap screw for use in any tapped 3/8-16 hole where a countersunk or flush-mount fastener profile is required.

Installation Notes

Install using the correct 7/32-inch hex key to avoid rounding the socket drive. Ensure the mating surface is properly countersunk to the correct 82-degree included angle before installation. Verify thread engagement depth meets fastener load requirements for the application. Follow applicable mechanical and structural codes when using fasteners in load-bearing assemblies.
