Value Collection 36865 Flat Socket Cap Screw 5/8-11

Product Description

The Value Collection 36865 is a flat socket cap screw designed for applications requiring a countersunk, low-profile fastening solution. It features an 82-degree flat head driven by a 3/8-inch hex socket and is fully threaded along its 1-1/2-inch overall length at a 5/8-11 UNC thread specification. Constructed from alloy steel with a black oxide finish, this fastener delivers solid mechanical strength and moderate corrosion resistance in indoor and protected outdoor environments. It meets ASME/ANSI B18.3 and ASTM F835 standards. Sold in packages of 10, it suits maintenance shops, fabricators, and industrial service technicians who need a reliable UNC-threaded flat-head cap screw in quantity.

This screw is appropriate for use in mechanical assemblies, machine frames, fixtures, and general industrial equipment where the fastener head must sit flush or below the mating surface. The 5/8-11 UNC coarse thread provides strong engagement in standard tapped holes. Fully threaded construction gives flexibility across a range of joint thicknesses within the 1-1/2-inch length. The black oxide finish is suited for interior steel assemblies or lightly oiled storage environments. Technicians in manufacturing maintenance, fabrication shops, and equipment assembly operations will find this a practical stock fastener.

Key Features

• 82-degree flat head sits flush or countersunk in mating material
• 3/8-inch hex socket drive for standard Allen key or hex bit installation
• 5/8-11 UNC fully threaded at 1-1/2 inches overall length
• Alloy steel construction for high tensile strength
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Meets ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed as an OEM-style replacement or stock fastener for any application requiring a 5/8-11 UNC flat socket cap screw with an 82-degree head angle per ASME/ANSI B18.3.

Installation Notes

Installation is performed by machinists, maintenance technicians, and fabricators using a 3/8-inch hex key or hex socket bit. Ensure the receiving hole is properly countersunk to 82 degrees and the tapped thread is clean before driving the fastener. Do not exceed the rated torque for the fastener grade and always verify thread engagement depth is adequate for the load. Black oxide finished fasteners should be kept lightly oiled in storage to maintain surface protection.
