Dan-loc Bolt Gasket 000-09-050 Fully Threaded Stud

Product Description

The DAN-LOC BOLT GASKET 000-09-050 is a fully threaded stud machined from Grade B7 alloy steel with a 1-1/8-8 unified coarse thread and an overall length of 5 inches. This stud is uncoated and carries no surface treatment, making it suitable for applications where post-installation coating or plating will be applied, or where bare alloy steel is acceptable. Fully threaded studs are used in bolted flange assemblies, pipe connections, pressure vessel joints, and structural bolting where a nut is threaded onto both ends to clamp components together. The Grade B7 material designation indicates a medium-carbon alloy steel heat-treated to high tensile strength, commonly specified in ASME and ASTM fastener standards for demanding industrial service.

This stud is used in industrial, mechanical, and trade applications requiring high-strength fastening in flanged pipe systems, pressure vessels, pumps, valves, and heavy equipment assemblies. It is appropriate for both new construction and maintenance and repair operations in commercial and industrial settings. Installers working in HVAC, plumbing, and mechanical piping systems frequently use Grade B7 fully threaded studs when assembling flanged connections at elevated pressures or temperatures.

Key Features

• Fully threaded along entire 5-inch length for maximum engagement flexibility
• 1-1/8-8 unified coarse thread form for reliable load distribution
• Grade B7 alloy steel construction for high tensile and yield strength
• Uncoated plain finish suitable for coating, galvanizing, or bare use
• Single-piece stud design compatible with standard hex nuts on both ends

Compatibility

Designed as an OEM-style replacement or new-installation fastener for industrial bolted assemblies requiring a 1-1/8-8 fully threaded Grade B7 alloy steel stud with a 5-inch overall length.

Installation Notes

Installation of threaded studs in flanged piping or pressure vessel assemblies should be performed by qualified mechanical or pipefitting tradespeople in accordance with applicable ASME or facility-specific torque and assembly procedures. Shut down and depressurize any system before removing or replacing fasteners in pressurized joints. Use the appropriate nut and washer specifications for the Grade B7 stud to ensure proper load distribution. Do not mix stud and nut material grades without verifying compatibility with the joint design requirements.
