Value Collection 49070 Hex Head Cap Screw 5/8-11 Grade B7

Product Description

The VALUE COLLECTION 49070 is a 5/8-11 UNC hex head cap screw with a 1-inch length under head, manufactured from Grade B7 alloy steel with an uncoated finish. Grade B7 material meets ASTM A193 standards, making it well-suited for bolting applications that demand reliable tensile and yield strength. This screw is used across industrial, mechanical, and structural installations where threaded fastener integrity is critical. Sold in a package of 25, it is a practical stocking choice for maintenance shops, industrial facilities, and trade contractors who regularly work with bolted flange, piping, and structural connections.

This hex head cap screw is appropriate for use in a wide range of commercial and industrial applications including pressure vessel assemblies, flange connections, piping systems, and structural bolting. The UNC thread form is the standard inch-series coarse thread, compatible with standard 5/8-11 threaded holes and nuts. The ASTM A193 Grade B7 designation is commonly specified in plumbing, HVAC, and mechanical piping specifications where elevated-strength fasteners are required by code or engineering design.

Key Features

• Grade B7 alloy steel construction meeting ASTM A193 requirements for high-strength bolting
• 5/8-11 UNC thread form for compatibility with standard inch-series threaded hardware
• 1-inch length under head for consistent engagement in standard bolted assemblies
• Uncoated finish suitable for applications where plating or coating is not required or specified
• Packaged in quantities of 25 per pack for efficient stocking and job-site use

Compatibility

Designed as an OEM-style replacement or stocking fastener for applications requiring 5/8-11 UNC hex head cap screws conforming to ASTM A193 Grade B7 specifications.

Installation Notes

Installation should be performed by a qualified mechanic, pipefitter, or trades professional familiar with applicable bolting standards and torque requirements for the specific assembly. Always consult the equipment manufacturer specifications or applicable code (such as ASME or ANSI piping standards) for proper torque values and bolt pattern sequencing. Inspect threads for damage before installation and ensure mating threaded components match the 5/8-11 UNC thread specification. Do not mix fastener grades within a bolted joint assembly.
