Value Collection 49080 Hex Head Bolt 5/8-11 4in Grade B7

Product Description

The VALUE COLLECTION 49080 is a 5/8-11 UNC hex head bolt with a 4-inch length under head, manufactured from alloy steel at material grade B7. This fastener is produced to ASTM A193 standards, a specification commonly required in high-temperature and high-pressure bolting applications. The uncoated, bright finish leaves the steel bare for applications where corrosion resistance is handled by the assembly environment or an applied coating. Licensed tradespeople and maintenance professionals working on pressure vessels, flanged pipe connections, and structural assemblies will encounter this bolt in both new construction and maintenance work.

This bolt is suited for industrial and mechanical applications where ASTM A193 B7 alloy steel fasteners are called out on engineering drawings or specifications. Typical use cases include bolting flanges on high-pressure piping systems, securing equipment in elevated-temperature environments, and anchoring structural steel components in demanding service conditions. It ships in a package quantity of 10, making it practical for small repairs or job-lot procurement.

Key Features

• 5/8-11 UNC thread — standard coarse-thread series for general industrial bolting
• 4-inch length under head — measured from bearing face to tip
• Alloy steel, Grade B7 — meets ASTM A193 for high-strength, elevated-temperature service
• Uncoated bright finish — no additional coating that could affect dimensional tolerance or conductivity
• Inch system of measurement — compatible with standard UNC tooling and hardware
• Package quantity of 10 — minimum order quantity of 1 package

Compatibility

Designed as an ASTM A193 Grade B7 compliant hex head fastener for use in flanged pipe assemblies, pressure vessel applications, and structural bolting where high-strength alloy steel hardware is specified.

Installation Notes

Installation should be performed by a licensed mechanic, pipefitter, or millwright following applicable code requirements and engineering torque specifications for the assembly. Always de-energize or depressurize the system before removing or installing fasteners in pressurized or live-load applications. Use a calibrated torque wrench to achieve proper clamping load; do not estimate by feel alone. Inspect thread engagement and seating surface condition before final torque.
