Value Collection R63061126 Flat Socket Cap Screw 1/2-13

Product Description

The VALUE COLLECTION R63061126 is a flat socket cap screw engineered for applications requiring a flush or countersunk fastener profile. Built from 18-8 stainless steel, it offers solid corrosion resistance suitable for wet, outdoor, or chemically exposed environments. The 82-degree flat head seats flush with or below the surface of the workpiece, eliminating protrusion. Drive engagement is through a 5/16-inch hex socket, providing reliable torque transfer with a standard hex key or socket driver. Thread specification is 1/2-13 UNC, with an overall length of 1.25 inches. This screw is a staple fastener for mechanical assemblies, brackets, and equipment panels across trade and industrial settings.

This flat socket cap screw is used in situations where a low-profile or recessed fastener is required and surface clearance is limited. Common installation scenarios include equipment housings, pump brackets, pipe supports, electrical panel structures, and HVAC frame assemblies. The UNC thread pattern makes it compatible with the vast majority of standard inch-system tapped holes found in domestic mechanical and structural components. Installers across plumbing, HVAC, electrical, and light industrial trades routinely use this fastener size in both new construction and service replacement work.

Key Features

• 18-8 stainless steel construction provides corrosion resistance in wet and mildly corrosive environments
• 82-degree flat head profile seats flush for a clean, low-clearance installation
• 5/16-inch hex socket drive for use with standard Allen or hex socket tools
• 1/2-13 UNC thread for broad compatibility with inch-system tapped holes
• 1.25-inch overall length suits moderate-depth fastening applications

Compatibility

Designed as a standard 1/2-13 UNC flat socket cap screw for use in any tapped or clearance-drilled application requiring an 82-degree countersunk flush-mount fastener in inch-system assemblies.

Installation Notes

Installation is performed with a 5/16-inch hex key or socket driver. Ensure the receiving hole is properly countersunk to an 82-degree angle to achieve full head seating. Power down or de-energize any equipment before fastening components on or near electrical or mechanical systems. Avoid over-torquing stainless steel fasteners, as galling can occur — applying an anti-seize compound to the threads is a common practice when working with stainless-to-stainless assemblies.
