Secure threaded fasteners with YZAN 243/271 Threadlocker, an anaerobic adhesive designed for metal applications. The blue 243 formula provides medium-strength locking and is removable for maintenance, while the red 271 formula offers high-strength locking for more permanent assemblies. Both help lock and seal threaded connections while resisting oil, water, corrosion, and high temperatures. Ideal for automotive, motorcycle, machinery, pipe fittings, equipment, and DIY repairs.
