Value Collection 721565BR Flat Socket Cap Screw 5/8-11 X 8 in

Product Description

The VALUE COLLECTION 721565BR is a flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. It features an 82-degree flat head driven by a 3/8-inch hex socket, making it compatible with standard Allen keys and hex drivers. Constructed from alloy steel with a black oxide finish, this screw delivers solid mechanical strength and modest corrosion resistance in indoor and sheltered environments. The 5/8-11 UNC thread is partially threaded along the 8-inch overall length. It meets ASME/ANSI B18.3 and ASTM F835 standards. Machinists, millwrights, and maintenance technicians typically install this type of fastener in structural assemblies, fixtures, and machinery where a low-profile head is required.

This screw is suited for industrial, commercial, and maintenance applications where a countersunk socket drive fastener is needed. The 5/8-11 UNC thread pitch is a common coarse-thread standard used in general-purpose machine assemblies, equipment frames, and structural steel connections. Partial threading is typical for longer fasteners where the shank provides shear strength and the threaded portion engages the mating nut or tapped hole securely. This screw is sold individually.

Key Features

• 82-degree flat head profile for flush or countersunk installations
• 3/8-inch hex socket drive compatible with standard hex keys and drivers
• Alloy steel construction for high tensile and shear strength
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Partially threaded shank along the 8-inch overall length
• Meets ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed as an OEM-style replacement or direct-use fastener for assemblies requiring a 5/8-11 UNC partially threaded flat socket cap screw with an 8-inch overall length and 82-degree countersunk head.

Installation Notes

Installation is typically performed by machinists, millwrights, or maintenance technicians using a 3/8-inch hex key or socket driver. Ensure the mating hole is properly countersunk to 82 degrees before installation to achieve full head seating. De-energize and lock out any equipment before fastener replacement per standard LOTO procedures. Do not overtighten; torque to values specified by the equipment manufacturer or applicable engineering standards for 5/8-11 alloy steel fasteners.
