Value Collection 011019P Hex Socket Cap Screw 2-56 Unc

Product Description

The VALUE COLLECTION 011019P is a hex socket cap screw designed for precision fastening applications where a low-profile, high-strength connection is required. This screw features a 2-56 UNC thread size, a 1/4 inch length under head, and a 5/64 inch hex drive socket. It is manufactured from alloy steel and finished with a black oxide coating that provides moderate corrosion resistance and a clean appearance. The part is fully threaded along its length, making it well suited for shallow blind-hole or through-hole installations where full thread engagement is needed. Machinists, assembly technicians, and maintenance professionals working with precision mechanical assemblies are the primary installers of this fastener.

This screw is used in applications where fine thread control and compact fastener geometry are priorities, including instrument panels, electronic enclosures, jigs and fixtures, and light mechanical assemblies. The 2-56 UNC thread designation makes it a standard fastener in small-format precision work across industries such as electronics manufacturing, aerospace ground support, and general precision machining. It conforms to ASME/ANSI B18.3 and ASTM A574 standards, confirming dimensional and mechanical compliance for professional-grade installations.

Key Features

• 2-56 UNC thread for precision fine-thread fastening in small-format assemblies
• Fully threaded shaft maximizes thread engagement in shallow holes
• 5/64 inch hex socket drive for use with standard hex key or Allen wrench sets
• Alloy steel construction provides strength appropriate for ASTM A574 rated applications
• Black oxide finish delivers moderate corrosion resistance and reduces light reflection
• Meets ASME/ANSI B18.3 and ASTM A574 dimensional and mechanical standards

Compatibility

Designed as an OEM-style replacement or standard-stock fastener for any application requiring a 2-56 UNC hex socket cap screw with a 1/4 inch length under head, conforming to ASME/ANSI B18.3 and ASTM A574 specifications.

Installation Notes

Installation is performed by machinists or assembly technicians using a 5/64 inch hex key or T-handle driver. De-energize or power down any assembly before installing or removing fasteners in electrical or electronic enclosures. Avoid over-torquing small-diameter alloy steel screws in tapped holes, as the fine 2-56 thread is susceptible to stripping at excessive torque. Verify hole thread condition and cleanliness before installation to ensure full thread engagement.
