The carbon steel (Type B) and stainless steel (Type BS) nuts install quickly and permanently into aluminium or steel sheets as thin as 1mm.The nut is inserted into a properly sized mounting hole in the metal sheet and then sufficient squeezing force is applied using a Pemserter tool or any standard press until the nut's flange contacts the mounting sheet. Once installation, the nut becomes a permanent part of an assembly and throughout the process no secondary operations are required.
Standard thread sizes of these RoHS-compliant fasteners range from M3 to M6 with Imperial equivalents. Two different shank lengths for each thread size are available to accommodate minimum and thicker sheets.
