Value Collection R63062363 Button Socket Cap Screw 1/2-13

Product Description

The VALUE COLLECTION R63062363 is a button socket cap screw designed for fastening applications where a low-profile head is required alongside reliable tensile strength. The screw features a 5/16-inch hex socket drive and is manufactured from 18-8 stainless steel with a bright, uncoated finish. It carries a 1/2-13 UNC thread designation, meaning 1/2-inch nominal diameter with 13 threads per inch, and a 1-1/2-inch length under the head. The head height measures 0.265 inches. Thread fit is Class 3A, indicating a standard external thread tolerance for general mechanical assembly. This fastener conforms to ANSI/ASME B18.3 standards and is suited for installation by maintenance technicians, millwrights, and mechanical contractors.

This button socket cap screw is appropriate for light to medium-duty mechanical assemblies where a rounded, low-profile head reduces snagging risk or where clearance is limited. Common applications include equipment panels, enclosure hardware, machine guards, brackets, and structural assemblies exposed to moisture or mild corrosion risk. The 18-8 stainless steel construction makes it a practical choice for indoor and outdoor environments where corrosion resistance is a factor. The right-hand UNC thread direction is standard for the majority of mechanical assembly work across commercial and industrial settings.

Key Features

• Low-profile button head reduces protrusion in tight-clearance assemblies
• 18-8 stainless steel construction provides corrosion resistance in wet or outdoor environments
• 5/16-inch hex socket drive for use with standard Allen keys or hex socket bits
• 1/2-13 UNC Class 3A thread fit for reliable engagement with standard UNC nuts and tapped holes
• Conforms to ANSI/ASME B18.3 fastener standard
• Bright, uncoated finish — no coating to flake, chip, or affect thread fit

Compatibility

Designed as a standard UNC replacement or new-installation fastener compatible with any 1/2-13 tapped hole or nut conforming to ANSI/ASME B18.3 specifications.

Installation Notes

Installation requires a 5/16-inch hex key or hex socket driver. Power down or de-energize any equipment before accessing fastener points on live systems. Stainless steel fasteners are susceptible to galling during installation — apply an appropriate anti-seize compound and install at moderate speed to prevent thread damage. Follow applicable mechanical codes and equipment manufacturer torque guidance for the specific assembly.
