METRIC NYLOC NUTS GRADE 6 TYPE T GALVANISED
Nyloc nuts have a nylon insert which binds with the male thread to create a locking action to help prevent loosening
Threads are metric coarse pitch
Hot dipped galvanised for corrosion resistance
Type T, manufactured to DIN 985
Due to the thickness of the zinc coating galvanised nuts are tapped oversize, therefore, galvanised nuts must be used with galvanised bolts but will be a loose fit on non galvanised threads.
