Dan-loc Bolt Gasket 000-09-105 Fully Threaded Stud B7

Product Description

The DAN-LOC BOLT GASKET 000-09-105 is a fully threaded stud machined from ASTM A193 Grade B7 alloy steel with an uncoated plain finish. It features a 1-1/8-8 UNC thread profile running the full length of its 10.5-inch overall length. Grade B7 alloy steel delivers high tensile strength and hardness, making this stud well suited for heavy load-bearing bolted assemblies. Licensed trades and industrial maintenance personnel use this fastener in high-stress flanged connections, pressure vessel assemblies, and structural bolting applications where standard carbon steel hardware would be undersized for the service requirement.

This stud is used in applications that demand a coarse-thread, large-diameter fastener with consistent material properties throughout. Typical install scenarios include pipe flange assemblies, heat exchanger heads, industrial equipment mounting, and heavy mechanical connections in commercial and industrial settings. Its full-thread configuration allows maximum engagement depth flexibility, letting the installer set nut position at any point along the stud length to suit varying stack-up thicknesses.

Key Features

• Full-length 1-1/8-8 UNC thread for adjustable nut positioning across the entire stud length
• Grade B7 alloy steel construction provides high tensile strength for demanding bolted joint service
• 10.5-inch overall length accommodates thick flange and stack-up assemblies
• Uncoated finish is compatible with field application of thread lubricants, anti-seize, or protective coatings as required by the job spec
• Coarse 8-TPI thread pitch resists cross-threading and speeds assembly in heavy industrial conditions

Compatibility

Designed as an OEM-style replacement or direct-use fully threaded stud for industrial flanged assemblies and mechanical connections requiring a 1-1/8-8 coarse-thread fastener in Grade B7 alloy steel.

Installation Notes

Installation is typically performed by licensed pipefitters, millwrights, or mechanical contractors working under applicable ASME or facility torque specifications. Verify thread engagement depth and nut seating before applying final torque. Apply an appropriate anti-seize compound or thread lubricant when specified by the flange or equipment manufacturer. Never reuse studs that show signs of galling, corrosion pitting, or stretch deformation.
