Value Collection 011023PR Hex Socket Cap Screw 2-56 Unc

Product Description

The VALUE COLLECTION 011023PR is a hex socket cap screw designed for precision fastening in mechanical assemblies, fixtures, and equipment. It features a 2-56 UNC thread form and a 1/2-inch length under the head, making it suitable for close-tolerance applications where a compact, high-strength fastener is required. The screw is fully threaded and driven with a 5/64-inch hex key. Constructed from alloy steel with a black oxide finish, it offers solid mechanical strength and moderate corrosion resistance in dry or lightly protected environments. Machinists, maintenance technicians, and assembly professionals commonly install this fastener.

This cap screw is used in light mechanical assemblies, instrument enclosures, jigs, and fixtures where a #2-56 UNC thread is specified. The black oxide coating reduces light reflection and provides a degree of surface protection suited to indoor or controlled environments. The fully threaded design maximizes thread engagement across the full length under the head, which is critical in thin-stock or blind-hole applications. This fastener ships in a package quantity of one unit, with a minimum order quantity of 100 pieces.

Key Features

• 2-56 UNC thread form for precision light-duty fastening
• 1/2 inch length under head, fully threaded for maximum engagement
• 5/64-inch hex drive for use with standard hex keys or Allen wrenches
• Alloy steel construction meets ASME/ANSI B18.3 and ASTM A574 standards
• Black oxide finish for surface protection and low-reflectance appearance

Compatibility

Designed as a standard replacement or stocking fastener for any application specifying a 2-56 UNC hex socket cap screw per ASME/ANSI B18.3.

Installation Notes

Installation is performed with a 5/64-inch hex key or Allen wrench. Ensure mating threads are clean and free of debris before installation. Apply appropriate thread-locking compound if vibration resistance is required by the assembly specification. Follow applicable ASME fastener torque guidelines for the #2-56 thread size and alloy steel material class.
