Who hasnt had the experience of having to strain to break free a stubborn fastener on a brake assembly or free a seized spark plug. Avoid those problems with STEELMAN Anti Seize Thread lubricant. This copper based lubricant protects against the types of rust and corrosion that lead to seized parts and stuck bolts, nuts, and other fasteners. Apply a small amount to the threads with the convenient, cap mounted brush when assembling and the parts will be just as easy to remove when it comes time for disassembly again. Great for a wide range of uses from brake assemblies, thermostat housing bolts, various sensors, exhaust manifolds, and can even be used in smaller projects such as gunsmithing and 3D printing.
