Value Collection 364-5203-01 Flat Socket Cap Screw

Product Description

The VALUE COLLECTION 364-5203-01 is a flat socket cap screw designed for precision fastening applications where a flush or countersunk head profile is required. It features an 82-degree flat head driven by a hex socket and is fully threaded along its 3/16-inch overall length. The screw is sized to a 2-56 UNC thread standard, making it suited for fine-pitch work in tight assemblies. Constructed from alloy steel with a black oxide finish, it offers solid mechanical strength with moderate corrosion resistance in controlled environments. This fastener is installed by machinists, assembly technicians, and maintenance professionals working on precision equipment and close-tolerance mechanical assemblies.

This screw is used in applications that require a low-profile or flush-mount fastener head, such as instrument panels, jigs, fixtures, and mechanical assemblies where clearance above the fastener head is limited. The 2-56 thread size is common in small-scale precision work, including electronics enclosures, optical mounts, and light-duty mechanical components. It conforms to ANSI B18.3, ANSI B18.8.2, ANSI B2.2, and MS16555 fastener standards, making it appropriate for applications with specification-controlled build requirements.

Key Features

• 82-degree flat head profile allows flush or countersunk installation
• Hex socket drive for precise torque application in tight spaces
• Fully threaded 3/16-inch length for maximum thread engagement
• Alloy steel construction provides high tensile strength
• Black oxide finish offers mild corrosion resistance and reduces light reflection
• Conforms to ANSI B18.3, ANSI B18.8.2, ANSI B2.2, and MS16555 standards

Compatibility

Designed for use in any application requiring a 2-56 UNC fully threaded flat socket cap screw with an 82-degree countersink angle, conforming to inch-system fastener standards.

Installation Notes

Installation requires a correctly sized hex socket driver or Allen key matched to the 2-56 screw drive to avoid rounding the socket. The mating hole should be prepared with an 82-degree countersink to allow proper head seating. Follow applicable assembly specifications and torque guidelines for 2-56 alloy steel fasteners as defined by the governing engineering standard for the application. Avoid cross-threading during installation given the fine pitch of the 2-56 thread form.
