Value Collection 211009PR Flat Socket Cap Screw 2-56

Product Description

The VALUE COLLECTION 211009PR is a flat socket cap screw designed for precision fastening applications in metalworking, machinery, and light fabrication. It features an 82-degree flat head profile that sits flush with or below the mating surface, keeping clearance profiles tight. The hex socket drive accepts a standard hex key for reliable torque transfer in confined spaces. Manufactured from alloy steel with a black oxide finish, this screw delivers solid corrosion resistance in controlled environments. At 3/16 inches in overall length with a 2-56 UNC thread, it is sized for small-diameter, fine-pitch fastening tasks common in instrument assemblies, jigs, and fixtures. Sold individually, with a minimum order quantity of 100 units.

This screw is suited for applications requiring a low-profile, flush-mount fastener in inch-measurement assemblies. The 2-56 UNC thread is a standard size used in precision instruments, electronics enclosures, small mechanical assemblies, and tooling fixtures. The black oxide finish makes it appropriate for indoor and low-humidity environments where mild corrosion protection is sufficient. Machinists, tool-and-die makers, and maintenance technicians working with small mechanical assemblies will find this screw a standard go-to for flush-head requirements.

Key Features

• 82-degree flat head profile seats flush with or countersunk below the mating surface
• Hex socket drive for high torque application in tight spaces
• Alloy steel construction for strength in small-fastener applications
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Fully threaded shank along the 3/16-inch overall length
• Meets ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed as an OEM-style replacement or stock fastener for any inch-measurement assembly requiring a 2-56 UNC fully threaded flat socket cap screw with an 82-degree countersink angle.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a correctly sized hex key or hex bit driver. Ensure the mating material is drilled and countersunk to the correct 82-degree angle before installation to achieve full flush seating. Power down or de-energize any equipment before accessing fastener locations on live assemblies. Avoid over-torquing small-diameter screws, as alloy steel fasteners at the 2-56 size can be susceptible to torsional shear if driven beyond their rated capacity.
