Castrol Stick Wax
Lubricant for nuts & bolts. Available in 15 oz. tubes or a case of 24 tubes (enough to do three to five thousand nuts). For best results, apply wax as a couple stripes along the threads where the nut will thread onto the bolt. Approximately 50% of input torque is consumed where the threads of the nut and bolt meet. Next, swipe the washer face of the nut, with the wax, where it will contact the flat washer. Approximately 40% of input torque is consumed where the nut contacts the flat washer.
Price: US $13.50 per stick + freight
