Value Collection 721014PR Flat Socket Cap Screw 2-56

Product Description

The VALUE COLLECTION 721014PR is a flat socket cap screw engineered for precision fastening in compact assemblies. It features a 2-56 UNC thread and measures 5/8 inches in overall length. The 82-degree flat head profile sits flush or countersunk with the mating surface, making it well suited for applications where a low-profile finish is required. The hex socket drive accepts a standard hex key for controlled installation torque. Constructed from alloy steel with a black oxide finish, this screw delivers solid mechanical strength and moderate corrosion resistance in interior or protected environments. Machinists, assembly technicians, and maintenance professionals are the typical installers.

This screw is used in precision mechanical assemblies, instrumentation enclosures, electronic hardware, and light industrial equipment where a flush-seating fastener is required. The fully threaded shank provides maximum thread engagement across the full 5/8-inch length. The 2-56 thread size targets fine-thread applications common in small-diameter hardware found in instrument panels, optical mounts, and similar compact mechanisms. This part is sold individually but requires a minimum order quantity of 100 pieces.

Key Features

• 82-degree flat head seats flush or countersunk in mating surfaces for a low-profile installation
• Hex socket drive for precise torque application with a standard hex key
• Fully threaded shank maximizes thread engagement along the full 5/8-inch length
• Alloy steel construction provides high tensile and shear strength
• Black oxide finish offers mild corrosion resistance and reduces light reflection
• Meets ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed as an OEM-style replacement or standard hardware component for any assembly requiring a 2-56 UNC fully threaded flat socket cap screw with an 82-degree head angle.

Installation Notes

Installation is performed by machinists or assembly technicians using a properly sized hex key or hex bit driver. Ensure the receiving hole is correctly countersunk to 82 degrees before driving the screw to prevent head deformation or improper seating. Do not apply power tools at high torque settings to small-diameter screws in this size range, as over-torquing can shear the fastener. Follow applicable engineering drawings or fastener specification standards for torque requirements specific to your assembly.
