Dan-loc Bolt Gasket 000-10-105 Fully Threaded Stud B7

Product Description

The DAN-LOC BOLT GASKET 000-10-105 is a fully threaded stud machined from alloy steel to ASTM A193 Grade B7 standards. The stud measures 10.5 inches in overall length with a 1-1/4-8 UNC thread form running the full length. An uncoated plain finish leaves the base alloy exposed, making it suitable for applications where coatings are applied on-site or where bare steel meets the service requirements. Fully threaded studs are used by pipefitters, millwrights, and industrial mechanics when a standard bolt head would interfere with the assembly or when nuts must be applied at both ends of the fastener.

This stud is suited to high-strength bolting applications common in flanged pipe connections, pressure vessels, heat exchangers, and structural assemblies. Grade B7 alloy steel is a widely specified material for high-temperature and high-pressure service environments in industrial and mechanical systems. The 1-1/4-8 thread size is a coarse-series designation frequently encountered in heavy pipe flange bolting, particularly in ANSI and ASME flange assemblies used in commercial and industrial mechanical systems.

Key Features

• Fully threaded along the entire 10.5-inch length for maximum engagement flexibility
• 1-1/4-8 UNC thread form for compatibility with standard industrial hex nuts and flange nuts
• Grade B7 alloy steel construction for high-strength, high-temperature service
• Uncoated finish suitable for field-applied coatings or bare-steel installations
• Sold individually, allowing single-unit procurement for maintenance and replacement work

Compatibility

Designed as an OEM-style replacement or direct-use fastener for industrial flanged assemblies and mechanical equipment requiring 1-1/4-8 fully threaded Grade B7 studs.

Installation Notes

Installation should be performed by a qualified pipefitter, millwright, or mechanical contractor following applicable ASME, ANSI, or facility-specific torque and bolting procedures. Always de-energize, depressurize, and isolate the system before replacing flange fasteners. Use calibrated torque equipment and apply fastener lubricant or anti-seize compound per the governing specification. Do not mix Grade B7 studs with lower-grade hardware in the same flange joint.
