Value Collection 49074 Hex Head Bolt 5/8-11 2in Grade B7 25pk

Product Description

The VALUE COLLECTION 49074 is a hex head bolt made from Grade B7 alloy steel, designed for high-strength fastening applications where reliable clamping force and material integrity are required. This bolt features a 5/8-11 Unified National Coarse (UNC) thread and measures 2 inches in length under the head. It is manufactured to ASTM A193 standards, a specification commonly required in pressure vessels, flanges, valves, and structural assemblies. The uncoated finish is typical for applications where a mating coating or plating will be applied on-site, or where the alloy's bare mechanical properties are specified by an engineer or code requirement. Sold in packs of 25.

This bolt is suited for industrial, mechanical, and structural installations including pipefitting, pressure equipment assembly, and general heavy-duty fastening. ASTM A193 Grade B7 fasteners are frequently specified in ASME flange assemblies, process piping, and high-temperature or high-pressure environments. Licensed plumbers, pipefitters, millwrights, and maintenance mechanics are the primary installers. The 5/8-11 UNC thread is compatible with standard hex nuts and washers of the same thread designation.

Key Features

• ASTM A193 Grade B7 alloy steel construction for high-strength fastening
• 5/8-11 UNC thread for compatibility with standard 5/8-inch hardware
• 2-inch length under head for precise bolt engagement in typical flange and structural applications
• Uncoated finish suitable for post-installation coating or bare-metal code-specified assemblies
• Sold in a pack of 25 for job-lot use

Compatibility

Designed as an ASTM A193-compliant Grade B7 hex head fastener for use with standard 5/8-11 UNC threaded nuts and hardware in pressure, structural, and mechanical assemblies requiring this specification.

Installation Notes

Installation should be performed by a qualified pipefitter, millwright, or licensed mechanic per applicable codes such as ASME B31.3 or relevant structural standards. De-energize, depressurize, and isolate any system before disassembling or replacing fasteners. Use a calibrated torque wrench and follow the engineer-specified torque sequence for flange and pressure-equipment applications. Do not mix Grade B7 bolts with lower-grade hardware in ASME-rated assemblies.
