Value Collection 63886 Flat Socket Cap Screw 1/2-13 X 2 in

Product Description

The VALUE COLLECTION 63886 is a flat socket cap screw designed for fastening applications where a flush or countersunk head profile is required. Sized at 1/2-13 x 2 inches overall length with a Unified National Coarse (UNC) thread standard, this screw accepts a 5/16-inch hex socket drive and features an 82-degree flat head angle for clean seating in countersunk holes. Constructed from 18-8 stainless steel, it offers reliable corrosion resistance in environments exposed to moisture or mild chemicals. It is a standard inch-measurement fastener suited for use by maintenance technicians, millwrights, pipefitters, and general tradespeople.

This flat socket cap screw is used in residential and commercial maintenance, equipment assembly, and structural fastening scenarios where a low-profile head is necessary to sit flush with or below a surface. The 1/2-13 UNC thread pattern is one of the most common coarse-thread sizes in inch-based mechanical systems, making this screw a frequent replacement or assembly fastener across HVAC equipment frames, pump housings, pipe flanges, and general mechanical assemblies.

Key Features

• 82-degree flat head seats flush in standard countersunk holes
• 5/16-inch hex socket drive for positive torque engagement
• 1/2-13 UNC thread for compatibility with standard inch-based tapped holes
• 18-8 stainless steel construction provides corrosion resistance in damp or chemically exposed environments
• 2-inch overall length suits medium-depth fastening applications

Compatibility

Designed as an OEM-style replacement or general-use fastener for any application requiring a 1/2-13 UNC flat socket cap screw with an 82-degree head angle and 5/16-inch hex socket drive in inch-measurement systems.

Installation Notes

Installation is performed with a 5/16-inch hex key or Allen driver; impact-rated hex bits are acceptable for powered installation. Ensure the mating hole is properly countersunk to 82 degrees to achieve full flush seating before torquing. De-energize any equipment and relieve system pressure before disassembling fastened joints on mechanical or fluid-handling systems. Stainless steel fasteners are susceptible to galling — apply an appropriate anti-seize compound when installing into stainless or aluminum tapped holes.
