Stainless steel bolts/nuts
Before installing stainless steel bolts and nuts:
Clean the threads and contact surfaces. Apply Anti-Seize Paste (Part-No. BKL.014/BAS.001) evenly and in
sufficient quantity to the screw head/nut contact surface and the thread using a brush or putty knife etc. to
avoid seizing of stainless steel.
