Highlights

• Medium removal torque anaerobic threadlocker adhesive
• Provides vibration, shock, and corrosion resistance for threaded fasteners
• One-component, medium viscosity formulation for controlled application
• Long open time for assembly flexibility
• Fast curing in the absence of air after assembly
• Designed for reliable locking and sealing of threaded components

Description

The 3M Scotch-Weld Threadlocker TL42 (7100039192) is a one-component anaerobic threadlocker adhesive designed to secure threaded fasteners against loosening caused by vibration, shock, and corrosion.

Its medium-viscosity formulation allows controlled dispensing and effective coverage on threaded assemblies, while the long open time supports flexible assembly operations. Once confined between metal surfaces and isolated from air, the adhesive cures quickly to create a durable locking bond.

The medium removal torque characteristic provides strong fastener retention while still allowing disassembly when maintenance or servicing is required, making it suitable for industrial and mechanical assembly applications.
