Value Collection 211012PR Flat Socket Cap Screw 2-56

Product Description

The VALUE COLLECTION 211012PR is a flat socket cap screw designed for precision fastening applications requiring a flush or countersunk head profile. Built from alloy steel with a black oxide finish, this screw features an 82-degree flat head and a hex socket drive. It carries a 2-56 UNC thread and measures 1/2 inch in overall length with full threading along the shank. Licensed mechanical contractors, machinists, and maintenance technicians use this fastener when low-profile head clearance is critical and corrosion resistance is needed in mild environments. The black oxide finish reduces light reflection and provides limited rust inhibition.

This screw is suited for light-duty mechanical assemblies, instrument panels, electrical enclosures, and precision equipment where a countersunk seating surface is required. The 2-56 thread size targets small-bore tapped holes common in sheet metal, thin plate, and machined components. Full threading allows engagement across the entire fastener length, which is advantageous in thin material applications. Sold in minimum order quantities of 100 pieces, this fastener is appropriate for shop stock, production runs, and service kit replenishment.

Key Features

• 82-degree flat head seats flush in standard countersunk holes
• Hex socket drive accepts standard hex keys and socket bits for torque control in confined spaces
• Fully threaded shank maximizes thread engagement in thin materials
• Alloy steel construction provides strength suitable for precision mechanical assemblies
• Black oxide finish offers mild corrosion resistance and reduced surface reflectivity
• Meets ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed as an OEM-style replacement or stock fastener for applications requiring a 2-56 UNC flat socket cap screw with an 82-degree head angle per ASME/ANSI B18.3.

Installation Notes

Installation requires a properly sized hex key or hex socket driver matched to the 2-56 screw head. The mating hole must be countersunk to an 82-degree included angle to achieve proper flush seating. De-energize any electrical equipment before fastener service in enclosures or panel assemblies. Avoid over-torquing, which can strip the small-diameter thread or shear the fastener head.
