Seal your Assembly with a Thread-Locker Solution from MRO


Our new line of Anaerobic Threadlockers are designed for locking and sealing fastener assemblies to prevent unintentional loosening of parts. Available in six (6) different strength formulas including medium strength blue, high strength red, high strength green penetrating, low strength viscosity red, low strength purple, high strength high temperature red, and oil resistant blue. Some threadlockers may be disassembled easily with hand tools and others form a more permanent and difficult to remove seal. We offer 10ml and 50ml bottles for your convenience. Visit individual product pages for specifications on each variety and appropriate uses.
