Dan-loc Bolt Gasket 000-07-055 Fully Threaded Stud B7

Product Description

The DAN-LOC BOLT GASKET 000-07-055 is a fully threaded stud machined from Grade B7 alloy steel with an uncoated plain finish. It features a 7/8-9 UNC thread form running the full length of its 5.5-inch overall length, giving installers continuous thread engagement at both ends. Grade B7 alloy steel is the standard material for high-strength bolting in pressure vessels, flanges, and industrial piping assemblies. At 1.48 pounds, this stud is suited for demanding mechanical and structural applications where consistent tensile strength and thread integrity are required. Licensed trades and maintenance professionals specify B7 studs for compliance with industry fastener standards.

This fully threaded stud is used in industrial and commercial applications including flanged piping connections, heat exchangers, pressure vessel closures, and structural bolted assemblies. Its 7/8-9 thread size is common in heavy mechanical systems where high clamping force and vibration resistance are needed. It is appropriate for use in both new installation and maintenance replacement scenarios across HVAC, plumbing, and industrial process piping environments where alloy steel fasteners are specified.

Key Features

• Fully threaded along entire 5.5-inch overall length for maximum engagement flexibility
• 7/8-9 UNC thread form for compatibility with standard heavy-duty nuts and couplings
• Grade B7 alloy steel construction provides high tensile and yield strength
• Uncoated plain finish suitable for use with thread lubricants or anti-seize compounds
• 1.48-pound weight consistent with full-length alloy steel construction at this diameter

Compatibility

Designed as an OEM-style replacement or new-install fastener for flanged connections, pressure vessel assemblies, and industrial bolting applications requiring a 7/8-9 fully threaded stud in Grade B7 alloy steel.

Installation Notes

Installation should be performed by a qualified mechanic, pipefitter, or maintenance technician familiar with industrial fastener torque procedures. Depressurize and de-energize any system before replacing studs in flanged or pressure vessel applications. Apply appropriate thread lubricant or anti-seize compound per the assembly specification before installation. Follow applicable ASME, ANSI, or facility-specific torque and bolt-up procedures for the joint being serviced.
