Value Collection MP63877 Flat Socket Cap Screw 3/8-16

Product Description

The VALUE COLLECTION MP63877 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 turned with a standard hex key or Allen wrench. The thread size is 3/8-16 UNC with an overall length of 1-1/4 inches. Constructed from 18-8 stainless steel, it offers solid corrosion resistance in wet, outdoor, or chemically active environments. This fastener is suited for mechanical assemblies, equipment mounting, and structural connections where a low-profile head is required.

This flat socket cap screw is used in a wide range of industrial, commercial, and trade applications. Common install scenarios include panel mounting, machinery frames, HVAC equipment brackets, plumbing fixture assemblies, and electrical enclosures where a flush fastener surface is necessary. The 3/8-16 UNC thread pattern is a standard coarse-thread specification widely used across North American manufacturing and mechanical trades. The 18-8 stainless steel construction makes it appropriate for both indoor and outdoor installations where moisture exposure is a concern.

Key Features

• 82-degree flat head seats flush in countersunk holes for a clean, low-profile finish
• 7/32-inch hex socket drive for use with standard Allen keys or hex bit drivers
• 3/8-16 UNC coarse-thread specification for broad compatibility with standard tapped holes
• 18-8 stainless steel construction provides corrosion resistance in wet and outdoor environments
• 1-1/4-inch overall length suits medium-depth fastening applications

Compatibility

Designed as a standard UNC coarse-thread flat socket cap screw compatible with any 3/8-16 tapped hole or countersunk through-hole requiring an 82-degree flat head seating angle.

Installation Notes

Installation is performed with a 7/32-inch hex key or Allen-style driver. Ensure the mating hole is properly countersunk to an 82-degree included angle before installation to achieve full head seating. Power down or de-energize any equipment before fastener replacement or assembly work. Avoid over-torquing stainless steel fasteners, as the material is susceptible to galling without appropriate anti-seize compound.
