Value Collection R63062684 Button Cap Screw 1/2-13 18-8 Ss

Product Description

The VALUE COLLECTION R63062684 is a button socket cap screw designed for fastening applications that require a low-profile head and high corrosion resistance. Sized at 1/2-13 UNC with a 1 inch length under head, this screw is driven by a 5/16 inch hex socket and conforms to ANSI/ASME B18.3 standards. Constructed from 18-8 stainless steel with a bright, uncoated finish, it provides reliable corrosion resistance in wet, outdoor, or chemically exposed environments. The button head style delivers a smooth, rounded top surface useful in applications where a flush or snag-free profile matters. Licensed tradespeople and industrial maintenance technicians commonly install this hardware in structural, mechanical, and equipment-assembly work.

This screw is suited for general mechanical assembly, equipment fabrication, and maintenance applications across residential, commercial, and light industrial settings. The 1/2-13 UNC thread class 3A fit provides standard tolerance engagement appropriate for most steel, aluminum, and composite assemblies. The right-hand thread direction follows conventional installation practice, making it compatible with standard tooling found in most trade shops and service vehicles.

Key Features

• 1/2-13 UNC thread form, class 3A fit for standard tolerance engagement
• 1 inch length under head for consistent grip depth across typical joint thicknesses
• 5/16 inch hex socket drive for use with standard Allen keys and socket drivers
• 18-8 stainless steel construction provides corrosion resistance in wet or outdoor environments
• Button head profile delivers a low-profile, rounded top surface to reduce snag points
• Conforms to ANSI/ASME B18.3 dimensional standards

Compatibility

Designed as an OEM-style replacement or standard-stock fastener for mechanical assemblies requiring 1/2-13 UNC button socket cap screws per ANSI/ASME B18.3. Verify thread engagement depth and material compatibility before installation.

Installation Notes

Installation is performed by machinists, millwrights, pipefitters, or general mechanical tradespeople using a 5/16 inch hex key or socket driver. Ensure all mating surfaces are clean and free of debris before threading. Confirm the receiving thread is tapped to 1/2-13 UNC and that thread length engagement meets design requirements. Do not over-torque stainless steel fasteners, as galling can occur during installation.
