Value Collection -36869-3 Flat Socket Cap Screw 5/8-11 X 3 in

Product Description

The VALUE COLLECTION -36869-3 is a flat socket cap screw designed for fastening applications that require a flush or countersunk head profile. It features an 82-degree flat head with a 3/8-inch hex socket drive and is manufactured from alloy steel with a black oxide finish for corrosion resistance. The screw measures 5/8-11 thread size by 3 inches in overall length and is fully threaded along its entire shank. It conforms to ASME/ANSI B18.3 and ASTM F835 fastener standards. Machinists, millwrights, maintenance technicians, and fabricators are the typical installers for this fastener type.

This flat socket cap screw is suited for mechanical assemblies, structural connections, and equipment fabrication where a low-profile head is required and the fastener must sit flush with or below the mating surface. The UNC thread standard and inch measurement system make it compatible with standard imperial-threaded fixtures and tooling. It is commonly used in industrial machinery, tooling plates, and general metalwork applications where alloy steel strength and a countersunk installation are specified.

Key Features

• 82-degree flat head for flush countersunk installations
• 3/8-inch hex socket drive for high-torque Allen wrench or hex bit engagement
• Fully threaded 5/8-11 UNC shank, 3 inches overall length
• Alloy steel construction for high tensile strength in demanding applications
• 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 standard-service fastener for applications requiring a 5/8-11 UNC fully threaded flat socket cap screw in inch-measurement systems.

Installation Notes

Installation is performed by machinists, fabricators, or maintenance technicians using a 3/8-inch hex key or hex socket bit. The mating material must be drilled and countersunk to an 82-degree angle to properly seat the flat head flush. Verify thread engagement depth meets structural requirements before final torque. Follow applicable industry standards and equipment manufacturer specifications for torque values when installing alloy steel fasteners in critical assemblies.
