Value Collection 581654BR Hex Socket Cap Screw 5/8-11

Product Description

The VALUE COLLECTION 581654BR is a hex socket cap screw designed for high-strength fastening in mechanical, industrial, and structural assemblies. Manufactured from alloy steel with a black oxide coating, this screw offers solid corrosion resistance and reduced light reflection in demanding shop and field environments. It features a 5/8-11 UNC thread size, a 4.25-inch length under head, and a 0.5-inch hex drive. The partial threading provides strong clamping force in load-bearing connections. This fastener meets ASME/ANSI B18.3 and ASTM A574 standards, making it suitable for precision and high-torque applications. Installation is typically performed by machinists, maintenance technicians, and industrial assemblers.

This socket cap screw is used across a wide range of industrial and mechanical applications including machinery assembly, equipment maintenance, structural fixturing, and tooling. The 5/8-11 UNC coarse thread is a common size in heavy-duty fastening scenarios. The black oxide finish makes it a standard choice where low-reflectivity or mild corrosion protection is needed. It is sold in a minimum order quantity of 10 pieces, with each package containing 1 piece.

Key Features

• 5/8-11 UNC coarse thread for secure engagement in standard tapped holes
• 4.25-inch length under head accommodates thicker material stacks
• Alloy steel construction meets ASTM A574 high-strength fastener requirements
• Black oxide coating provides mild corrosion resistance and low-glare surface
• 0.5-inch hex socket drive for use with standard Allen or hex keys
• Partially threaded shank allows precise clamping without thread engagement through full grip length

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw for use in any 5/8-11 UNC tapped hole requiring a high-strength alloy steel fastener with a hex drive.

Installation Notes

Install using a 0.5-inch hex key or Allen wrench rated for the applied torque. Ensure the receiving hole is correctly tapped to 5/8-11 UNC before installation. Inspect threads for damage before seating the fastener. Power down or de-energize any equipment before performing fastener service on live assemblies.
