Value Collection 49078 Hex Head Bolt 5/8-11 Grade B7

Product Description

The VALUE COLLECTION 49078 is a hex head bolt engineered for high-strength fastening applications requiring reliable clamping force and material integrity. Sized at 5/8-11 UNC thread, it measures 3 inches under the head and is manufactured from alloy steel to Grade B7 specifications. The uncoated finish is standard for applications where coatings would interfere with assembly tolerances or subsequent treatment. Compliance with ASTM A193 confirms the bolt meets recognized standards for high-temperature and high-pressure service applications. Licensed fastener professionals and industrial maintenance technicians rely on this specification for pressure vessel, flange, and structural bolting work.

This bolt is suited for industrial and commercial bolting applications where ASTM A193 Grade B7 alloy steel fasteners are called out by specification. Typical installations include pressure vessel flanges, pipe flanges, heat exchangers, and structural connections operating under elevated temperature or stress conditions. The 5/8-11 UNC thread is a common heavy-duty fastener size found across petrochemical, power generation, and general manufacturing environments. Sold in packages of 10 with a minimum order quantity of 1 package.

Key Features

• 5/8-11 UNC thread form for broad compatibility with standard hex nuts and threaded holes
• 3-inch length under head for consistent clamping reach in flange and structural assemblies
• Alloy steel construction to ASTM A193 Grade B7 for high tensile and yield strength
• Uncoated finish maintains dimensional tolerances and allows field-applied coatings or galvanic isolation methods as needed
• Packaged in quantities of 10, minimizing handling and supporting job-site kitting

Compatibility

Designed as an ASTM A193 Grade B7 compliant hex head bolt for use wherever 5/8-11 UNC alloy steel fasteners are specified in industrial, pressure vessel, or structural bolting applications.

Installation Notes

Installation should be performed by qualified mechanical or industrial maintenance personnel following applicable codes and engineered torque specifications for the assembly. Always de-energize, depressurize, and isolate any system before replacing or installing fasteners on pressurized or energized equipment. Use calibrated torque tools and follow the project or equipment manufacturer's fastener torque table for Grade B7 alloy steel at the applicable service temperature. Do not mix Grade B7 bolts with non-compatible nuts or washers, as mismatched grades can compromise joint integrity.
