Dan-loc Bolt Gasket 000-07-045 Threaded Stud 7/8-9 B7

Product Description

The DAN-LOC BOLT GASKET 000-07-045 is a fully threaded stud machined from alloy steel to ASTM A193 Grade B7 specifications. It is threaded along its entire 4.5-inch overall length at a 7/8-9 UNC thread pitch with no plain shank section, allowing full engagement from either end. Grade B7 alloy steel delivers the high tensile strength and temperature resistance required in demanding fastening applications including flanged pipe connections, pressure vessels, and structural assemblies. The uncoated finish is standard for field use where plating is not required or where field coating will be applied after installation.

This stud is suited for industrial, commercial, and trade applications where high-strength, fully threaded fasteners are specified. Typical uses include flange bolt-up work in plumbing and HVAC piping systems, pressure equipment assembly, and general mechanical construction requiring a B7-grade fastener. Plumbers, pipefitters, millwrights, and mechanical contractors routinely stock B7 threaded studs for flanged connection work.

Key Features

• Fully threaded 7/8-9 UNC profile along the entire 4.5-inch length
• Alloy steel construction to ASTM A193 Grade B7 material grade
• Uncoated plain finish suitable for field use or post-installation coating
• Compatible with standard 7/8-9 hex nuts and flanged hardware
• Single-piece per package quantity for precise procurement

Compatibility

Designed for use with standard 7/8-9 UNC threaded nuts and hardware in flanged piping, pressure vessel, and structural fastening applications where ASTM A193 Grade B7 alloy steel studs are specified.

Installation Notes

Installation is performed by qualified pipefitters, plumbers, or mechanical contractors following applicable codes such as ASME B31.1 or ASME B16.5 for flanged connections. Depressurize and isolate the system completely before disassembling any flanged joint. Use calibrated torque equipment when specified by the flange or equipment manufacturer, and follow the required bolt-up sequence for the flange class being serviced. Inspect thread condition before installation and do not install studs with damaged or contaminated threads.
