Value Collection 721505PR Flat Socket Cap Screw 2-56

Product Description

The VALUE COLLECTION 721505PR is a flat socket cap screw designed for precision fastening applications where a low-profile, flush-mount head is required. This screw features a hex socket drive and is manufactured from alloy steel with a black oxide finish for corrosion resistance and reduced light reflection. The 2-56 UNC thread and 1/8-inch overall length make it suited for compact assemblies where standard cap screws would protrude. Fully threaded along its length, it provides maximum thread engagement in thin materials. It is typically installed by machinists, tool and die technicians, and mechanical assemblers working in electronics, instrumentation, or precision equipment.

This fastener is used in applications requiring a countersunk, flush-mount fastening solution with a small-diameter, fine-pitch thread. The 2-56 thread size is common in light-duty assemblies, enclosures, and instrument panels where space constraints prohibit larger fasteners. The black oxide finish is appropriate for indoor use and controlled environments. Meets ASME/ANSI B18.3 and ASTM F835 standards. Sold individually with a minimum order quantity of 100 pieces per order.

Key Features

• Flat head profile allows flush or countersunk installation in mating material
• Hex socket drive accommodates a standard hex key for high-torque engagement in tight spaces
• Fully threaded along the 1/8-inch body length for maximum thread engagement
• Alloy steel construction provides strength suitable for light-duty precision assemblies
• Black oxide finish reduces surface reflection and offers mild corrosion protection in dry environments
• Conforms to ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed as an OEM-style replacement or standard-stock fastener for any application requiring a 2-56 UNC flat socket cap screw with 1/8-inch overall length per ASME/ANSI B18.3 specifications.

Installation Notes

Installation is performed with an appropriate hex key or hex bit driver sized for a number 2 socket cap screw. Ensure the receiving hole is properly countersunk to the correct angle to achieve a flush head seating. Power down or de-energize any assembly before installing fasteners in electrical or electronic enclosures. Do not over-torque; alloy steel small-diameter screws at this size are susceptible to thread stripping if torque is not controlled.
