Value Collection 63879 Flat Socket Cap Screw 3/8-16

Product Description

The VALUE COLLECTION 63879 is a flat socket cap screw designed for applications where a flush or countersunk fastener profile is required. Featuring a 3/8-16 UNC thread and an overall length of 1-3/4 inches, this screw is fully threaded from tip to head. The 82-degree flat head seats into a standard countersunk hole, and the 7/32-inch hex socket drive accepts a standard hex key or Allen wrench. Constructed from 18-8 stainless steel, it offers reliable corrosion resistance in wet, humid, or mildly chemical environments. Installers in plumbing, HVAC equipment assembly, pool equipment, and light structural applications regularly specify this fastener type where a low-profile head is needed.

This screw is appropriate for residential and light commercial applications where a countersunk fastener is required to sit flush with or below the mating surface. It is commonly used in equipment panels, brackets, enclosures, and mechanical assemblies across HVAC, plumbing, and pool service work. The fully threaded shank provides maximum thread engagement across the full length of the fastener, making it well suited for thin materials and short through-bolt applications. This item ships in a minimum order quantity of 50 pieces with a package quantity of 1.

Installation Notes

Installation is typically performed with a 7/32-inch hex key or Allen wrench. Ensure the mating material is countersunk to 82 degrees before installing to achieve full flush seating. De-energize and depressurize any equipment before fastener replacement or panel access. Apply thread-locking compound or anti-seize as required by the specific application and applicable codes.
