Lubricants provide many benefits to a bolted joint. They ease the amount of energy required to tighten the bolt; they provide better wear resistance; they make disassembly much easier; and they prevent corrosion that can permanently weld surfaces together. However, the use of a lubricant on the threads and under the bolt head – whether solid film, grease or oil – adds a layer of uncertainty to the security of the joint.
