Value Collection R63061062 Button Socket Cap Screw 2-56

Product Description

The VALUE COLLECTION R63061062 is a 2-56 button socket cap screw designed for applications requiring a low-profile head and reliable clamping force in tight clearances. Manufactured from 18-8 stainless steel with a bright, uncoated finish, this fastener resists corrosion in mildly harsh environments. The hex socket drive accepts a standard hex key or Allen wrench for installation in confined spaces where a conventional screwdriver cannot reach. At 0.125 inches of length under the head and a head height of 0.046 inches, this screw is suited for compact assemblies where vertical clearance is limited. The thread conforms to Unified National Coarse (UNC) standards with a 3A thread fit class and right-hand thread direction, meeting ANSI/ASME B18.3 fastener specifications.

This fastener is used across a range of light-duty mechanical assemblies, instrument panels, enclosures, electrical equipment, and HVAC component brackets where a small-diameter, corrosion-resistant screw is required. The 2-56 thread size is common in precision equipment, control boards, and terminal block mounting applications. Machinists, assembly technicians, electricians, and HVAC service professionals routinely use fasteners of this type during equipment fabrication, repair, and field service work. The button head profile distributes clamping load over a wider surface area compared to a flat or pan head, reducing the risk of surface damage on thin or soft substrates.

Key Features

• Button head profile provides a low-profile, rounded appearance with broad load distribution
• 18-8 stainless steel construction offers corrosion resistance in general-purpose environments
• Hex socket drive allows installation in recessed or confined locations with a hex key
• 2-56 UNC threading conforms to ANSI/ASME B18.3 for dimensional consistency
• 3A thread fit class ensures accurate thread engagement and reliable torque transfer
• Bright, uncoated finish maintains base material properties with no added coating thickness

Compatibility

Designed as a standard 2-56 UNC button socket cap screw for use in any application requiring an ANSI/ASME B18.3-compliant fastener of this thread size and head style.

Installation Notes

Install using a correctly sized hex key to avoid rounding the socket drive recess. De-energize any electrical equipment fully before fastening or removing screws in control panels or terminal enclosures. Verify thread engagement depth against substrate thickness to ensure adequate clamp load without bottoming out. Follow applicable mechanical assembly standards and torque guidelines for 2-56 stainless fasteners as specified in your project documentation.
