Value Collection 872429BR Hex Socket Cap Screw 5/8-11

Product Description

The VALUE COLLECTION 872429BR is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, industrial equipment, and structural connections. It features a 5/8-11 UNC thread and a 3-1/2 inch length under head, making it suited for applications requiring a longer reach with a partially threaded shank. The fastener is machined from alloy steel and finished with a zinc-plated coating for basic corrosion resistance. Drive engagement is via a 1/2 inch internal hex socket. This screw is installed by machinists, millwrights, maintenance technicians, and mechanical contractors working with standard inch-series fastener specifications.

This cap screw is used across a wide range of industrial and mechanical applications including machinery frames, equipment mounting, bracket assemblies, and structural bolted joints. The partially threaded shank helps maintain clamp load and improves shear performance in close-tolerance installations. It conforms to ASME B18.8 and ASTM A574 standards, which govern dimensional and mechanical property requirements for socket cap screws in inch-series sizes.

Key Features

• 5/8-11 UNC thread for compatibility with standard inch-series tapped holes
• 3-1/2 inch length under head suits deep reach fastening applications
• 1/2 inch internal hex drive for high torque input with standard hex keys or sockets
• Partially threaded shank improves shear resistance and clamp load distribution
• Alloy steel construction meets ASTM A574 mechanical property requirements
• Zinc-plated finish provides baseline corrosion protection for general indoor use

Compatibility

Designed as a standard ASME B18.8 and ASTM A574 compliant hex socket cap screw for use in any 5/8-11 UNC tapped hole requiring a partially threaded alloy steel fastener with a 1/2 inch hex drive.

Installation Notes

Installation is performed by machinists, millwrights, or maintenance technicians using a 1/2 inch hex key or socket driver. Ensure mating threads are clean and free of debris before installation. Apply thread lubricant or thread-locking compound as required by the assembly specification. Follow the equipment manufacturer torque specification for the fastener grade and application — do not estimate torque without a reference value.
