Boaters know the pain of neglecting to lubricate threads better than many people. Grease can work to ensure that removal is easy after exposure to water and salt, but dedicated anti-seize compounds work better. Most grease is designed for use as a lubricant on moving parts.
Anti-seize compounds are generally petroleum grease with graphite and aluminum, copper or other metal added and designed to prevent threads from corroding and sticking. ( The Star brite Anti-Seize Thread Lubricant shown contains molybdenum)
Anti-seize also prevents, or at least inhibits, galling–which is a form of cold welding that can occur, often with stainless steel fasteners. If you’ve ever had a stainless-steel nut thread half-way on and then freeze up and stop cold, you know what galling is.
Consider adding anti-seize thread coating to your boating tool kit.
