Value Collection R63061163 Flat Socket Cap Screw

Product Description

The VALUE COLLECTION R63061163 is a flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. It features an 82-degree flat head with a 5/16-inch hex socket drive, accepting a standard hex key for installation and removal. The thread size is 1/2-13 UNC with an overall length of 1-1/2 inches. Constructed from 18-8 stainless steel, this screw offers solid corrosion resistance, making it suitable for environments exposed to moisture, chemicals, or outdoor conditions. It is a common choice for mechanical assemblies, equipment enclosures, and structural connections where a low-profile head is required.

This screw is used across a wide range of trade and industrial applications, including HVAC equipment assembly, plumbing fixture mounting, electrical enclosure fabrication, and general mechanical installations. The 1/2-13 UNC thread pattern is one of the most common coarse-thread standards in inch-based fastener systems, making this screw broadly compatible with standard threaded inserts, nuts, and tapped holes found in commercial and industrial equipment. The flat head seats flush with the surface when installed in a properly sized countersunk hole.

Key Features

• 82-degree flat head profile seats flush in countersunk holes, eliminating protrusion above the work surface
• 5/16-inch hex socket drive for use with standard Allen or hex key tools
• 1/2-13 UNC thread standard — widely compatible with inch-based hardware and tapped assemblies
• 18-8 stainless steel construction provides corrosion resistance in wet or chemically active environments
• Overall length of 1-1/2 inches measured from the top of the head to the tip
• Minimum order quantity of 5 units supports small-batch repair and replacement needs

Compatibility

Designed for use in any application requiring a 1/2-13 UNC flat socket cap screw with an 82-degree countersunk head. Fits standard countersunk holes sized for 1/2-inch inch-series fasteners.

Installation Notes

Installation is performed with a 5/16-inch hex key or Allen wrench; confirm the mating hole is properly countersunk to 82 degrees before seating. De-energize or shut down any equipment before fastener service to prevent injury. Avoid cross-threading by starting the screw by hand and verifying thread engagement before applying torque. Stainless steel fasteners are prone to galling — apply an appropriate anti-seize compound when installing into stainless or aluminum threaded holes.
