Value Collection 63877 Flat Socket Cap Screw 3/8-16

Product Description

The VALUE COLLECTION 63877 is a flat socket cap screw designed for applications requiring a flush or countersunk fastening profile. The 82-degree flat head seats flush with the mating surface when installed in a properly countersunk hole, eliminating protrusion that could interfere with adjacent components or moving parts. Driven by a 7/32-inch hex socket, it delivers reliable torque transfer in tight spaces. Manufactured from 18-8 stainless steel, this screw resists corrosion in wet, humid, and mildly corrosive environments. The 3/8-16 UNC thread pattern is a standard coarse thread suitable for use in metal, plastic, or threaded inserts across a wide range of industrial and mechanical assemblies.

This flat socket cap screw is used across industrial maintenance, mechanical assembly, HVAC equipment panels, pump housings, enclosures, and structural fixtures where a flush fastener surface is required. The 18-8 stainless steel construction makes it appropriate for both indoor and outdoor installations where moisture exposure is a factor. It is commonly installed by millwrights, maintenance technicians, and mechanical contractors working on equipment assembly or field repair. Minimum order quantity is 50 pieces.

Key Features

• 82-degree flat head seats flush in countersunk holes, eliminating surface protrusion
• 7/32-inch hex socket drive for reliable torque in confined spaces
• 18-8 stainless steel construction provides corrosion resistance in wet and humid environments
• 3/8-16 UNC coarse thread for broad compatibility with standard threaded holes and inserts
• Overall length of 1-1/4 inches for medium-depth fastening applications

Compatibility

Designed as a standard inch-series flat socket cap screw with 3/8-16 UNC threading, suitable for use in any application requiring a countersunk hex socket fastener of this thread size and length.

Installation Notes

Installation requires a 7/32-inch hex key or socket bit. The mating hole must be countersunk to an 82-degree included angle to achieve a proper flush seating of the flat head. De-energize or lock out any equipment before fastener installation or removal per applicable OSHA lockout/tagout procedures. Avoid cross-threading by starting the screw by hand before applying drive torque.
