Value Collection 872431BR Hex Socket Cap Screw 5/8-11 Unc

Product Description

The VALUE COLLECTION 872431BR is a hex socket cap screw designed for high-strength mechanical fastening in industrial, commercial, and general manufacturing applications. The screw features a 5/8-11 UNC thread size and measures 4 inches under the head, with partial threading along the shank. Drive engagement is through a 1/2-inch hex socket. Constructed from alloy steel with a zinc-plated finish, this cap screw provides reliable tensile strength with basic corrosion resistance. It conforms to ASME B18.8 and ASTM A574 standards, making it suitable for applications where dimensional consistency and material strength are required. Installation is performed with a standard 1/2-inch hex key or socket driver.

This cap screw is used in fabrication, machine assembly, structural fastening, and maintenance repair operations across industrial and commercial settings. The partially threaded shank allows the unthreaded portion to bear shear loads, which is useful in applications where precision alignment or load distribution across the grip length is required. Machinists, millwrights, maintenance technicians, and general contractors commonly install this type of fastener when torque-critical bolted connections are specified.

Key Features

• 5/8-11 UNC thread size for compatibility with standard inch-series tapped holes
• 4-inch length under head with partial threading for shear-load applications
• 1/2-inch internal hex drive for high-torque installation with standard hex keys or socket drivers
• Alloy steel construction conforming to ASTM A574 for elevated tensile strength
• Zinc-plated finish provides basic corrosion resistance for indoor and light-duty environments
• Meets ASME B18.8 dimensional standards for consistent fit and interchangeability

Compatibility

Designed as a standard replacement or stock fastener for any application requiring a 5/8-11 UNC partially threaded hex socket cap screw per ASME B18.8 and ASTM A574 specifications.

Installation Notes

Install using a 1/2-inch hex key or socket driver; ensure the mating tapped hole meets 5/8-11 UNC thread specification before installation. De-energize and lock out any equipment being serviced before removing or replacing fasteners in mechanical assemblies. Do not reuse fasteners that show signs of thread damage, galling, or corrosion. Fastener torque requirements are determined by the equipment manufacturer or applicable engineering specifications and are not provided here.
