With Loctite 241, you reliably lock and seal fine threaded assemblies up to size M12 against shock and vibration. Thanks to its low viscosity, the liquid formula penetrates smoothly into small fastener threads. It cures anaerobically between close-fitting metal surfaces, including steel, brass, and stainless steel. The medium strength ensures your machinery and precision components stay securely fastened under dynamic loads, yet allows straightforward disassembly using standard hand tools whenever maintenance is needed. The handy 50 ml bottle enables quick and precise application.
