Value Collection 36868 Flat Socket Cap Screw 5/8-11 Alloy Steel

Product Description

The VALUE COLLECTION 36868 is a flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. Measuring 5/8-11 thread size by 2-1/4 inches in overall length, this screw is fully threaded and features an 82-degree flat head driven by a 3/8-inch hex socket. Constructed from alloy steel with a black oxide finish, it delivers solid mechanical strength alongside moderate corrosion resistance. This fastener meets ASME/ANSI B18.3 and ASTM F835 standards, making it a reliable choice for precision and structural assemblies. Sold in packages of 10.

This flat socket cap screw is suited for general industrial, mechanical, and structural applications where a countersunk fastener is required to sit flush with or below the mating surface. The UNC thread standard and alloy steel construction make it appropriate for use in machine components, tooling fixtures, brackets, and equipment assemblies. Installation is typically performed by machinists, millwrights, or maintenance technicians working in light to heavy industrial environments.

Key Features

• 82-degree flat head profile allows flush or countersunk installation
• 3/8-inch hex socket drive for use with standard Allen or hex key tooling
• Fully threaded 5/8-11 UNC shank for maximum thread engagement
• Alloy steel construction provides high tensile strength
• Black oxide finish offers mild corrosion resistance and reduces light reflection
• Meets ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard UNC-thread flat socket cap screw compatible with 5/8-11 tapped holes per ASME/ANSI B18.3 specifications in industrial and mechanical assemblies.

Installation Notes

Power down and de-energize any equipment before fastener installation or replacement. Use a properly sized 3/8-inch hex key or Allen driver to avoid rounding the socket drive. Ensure the mating surface is properly countersunk to the correct 82-degree angle before seating the screw. Consult applicable mechanical or structural codes for torque and fastener requirements specific to your application.
