Value Collection 364-5204-01 Flat Socket Cap Screw

Product Description

The VALUE COLLECTION 364-5204-01 is a flat socket cap screw designed for precision fastening applications where a flush or countersunk profile is required. It features an 82-degree flat head with a hex socket drive and is fully threaded along its 1/4-inch overall length. The thread size is 2-56 UNC, making it suited for fine-pitch work in tight assemblies. Constructed from alloy steel with a black oxide finish, this screw offers solid mechanical strength and moderate corrosion resistance in protected environments. Installation requires a hex key of the appropriate size for a 2-56 socket head fastener.

This screw is intended for use in mechanical assemblies, instrument housings, electronics enclosures, and precision equipment where a low-profile head is necessary to sit flush with or below the mating surface. The 2-56 UNC thread is common in small-device and instrument fabrication. The black oxide finish blends into dark assemblies and provides light surface protection. This fastener is sold individually but carries a minimum order quantity of 100 units, making it appropriate for production runs, shop stock, or repair inventory.

Key Features

• 82-degree flat head profile for flush or countersunk installations
• Hex socket drive for precise torque application in confined spaces
• Fully threaded 1/4-inch length maximizes thread engagement in shallow assemblies
• Alloy steel construction provides high tensile strength for its size class
• Black oxide finish offers light corrosion resistance and a low-reflectance appearance
• Meets ANSI B18.3, ANSI B18.8.2, ANSI B2.2, and MS16555 fastener standards

Compatibility

Designed as a standard 2-56 UNC flat socket cap screw suitable for use in any application requiring an ANSI B18.3-compliant countersunk hex socket fastener at this thread size and length.

Installation Notes

Installation is performed with a hex key or hex bit driver sized for a 2-56 socket head screw. Ensure the mating hole is properly countersunk to 82 degrees to allow the head to seat flush. Do not exceed the screw's rated drive torque, as the small cross-section of a 2-56 fastener is susceptible to torsional failure if over-driven. Confirm thread engagement depth and hole alignment before final tightening.
