Value Collection 011021PR Hex Socket Cap Screw 2-56 Unc

Product Description

The VALUE COLLECTION 011021PR is a hex socket cap screw designed for precision fastening applications requiring a compact, high-strength connection. Built to ASME/ANSI B18.3 and ASTM A574 standards, this screw features a 2-56 UNC thread size with a 3/8-inch length under head and full threading from head to tip. The alloy steel construction delivers the tensile strength required for demanding machine assembly, instrumentation, and close-tolerance mechanical work. A black oxide coating provides moderate corrosion resistance and a clean, low-glare appearance. The 5/64-inch hex socket drive allows precise torque application with a standard hex key in confined or recessed mounting locations.

This cap screw is suited for light mechanical assemblies, electronic enclosures, instrumentation panels, and precision equipment where a small-diameter fully threaded fastener is required. The 2-56 UNC coarse thread is a common specification in miniature machine screw applications across manufacturing, maintenance, and repair environments. Installers working in electronics, light fabrication, and equipment service will find this screw compatible with standard 2-56 tapped holes. Sold individually with a minimum order quantity of 100 pieces.

Key Features

• 2-56 UNC thread for compatibility with standard miniature tapped holes
• Fully threaded 3/8-inch length under head for maximum thread engagement
• 5/64-inch hex socket drive for use with standard hex keys in recessed applications
• Alloy steel construction meets ASTM A574 mechanical requirements
• Black oxide finish provides moderate corrosion resistance and low-glare appearance
• Meets ASME/ANSI B18.3 dimensional standards for socket cap screws

Compatibility

Designed as a standard replacement or stock fastener for any application requiring a 2-56 UNC fully threaded hex socket cap screw with a 3/8-inch length under head.

Installation Notes

Installation is performed with a 5/64-inch hex key or Allen driver. Verify the mating tapped hole is clean, undamaged, and cut to 2-56 UNC specification before driving. Do not exceed the torque rating appropriate for ASTM A574 alloy steel miniature cap screws. Ensure equipment is de-energized or depressurized before fastener replacement in live assemblies.
