Dan-loc Bolt Gasket 000-07-085 Fully Threaded Stud

Product Description

The DAN-LOC BOLT GASKET 000-07-085 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 entire length of the fastener and measures 8.5 inches overall. Fully threaded studs of this type are used in bolted flange assemblies, pressure vessel connections, pipe flanges, and structural clamping applications where a nut must be engaged on both ends. The B7 material grade provides the elevated tensile strength and temperature resistance demanded by industrial and mechanical trade applications.

This stud is suited for use in commercial and industrial settings where high-strength threaded fasteners are required. Common applications include flange bolting on HVAC equipment, piping systems, heat exchangers, and pump assemblies. Licensed pipefitters, millwrights, plumbers, and mechanical contractors typically specify Grade B7 fully threaded studs for bolted connections subject to elevated temperatures or high clamping loads. The 7/8-9 thread size is a standard coarse-thread designation widely used in industrial fastener specifications.

Key Features

• Grade B7 alloy steel construction for high tensile strength and temperature resistance
• Fully threaded along the entire 8.5-inch length for maximum engagement flexibility
• 7/8-9 UNC coarse thread form compatible with standard heavy hex nuts and couplings
• Uncoated plain finish suitable for applications where coating buildup clearance is critical
• Single-piece stud design eliminates separate bolt-and-nut threading alignment issues

Compatibility

Designed as a standard Grade B7 fully threaded stud for industrial flange, pressure vessel, and mechanical clamping assemblies requiring a 7/8-9 thread and 8.5-inch overall length.

Installation Notes

Installation is typically performed by licensed pipefitters, millwrights, or mechanical contractors working to ASME or ASTM fastener specifications. Always de-energize, depressurize, and isolate the system before replacing studs in flanged connections. Use calibrated torque equipment and follow the applicable flange or equipment manufacturer torque sequence. Inspect threads for damage before installation and use appropriate thread lubricant or anti-seize compound as specified by the joint design.
