PTFE, XYLAN coating on Nuts & stud bolts significantly reduce the amount of make up torque lost to friction, Removing much of the uncertainty from predicting clamp loads. Also eliminates the problem of galling which occurs with Metals such as stainless steel. Resist corrosion In and sea water and and in chemical environment. This prevents nuts from freezing & Significantly reduce Break-out Torque.
