This low-profile hex nut is made from A2 stainless steel and manufactured to DIN 439-2 and ISO 4035 standards. It features a metric thread with a left-hand (LH) orientation, which is primarily used on components that rotate clockwise to prevent loosening. The strength class is 035, indicating a reduced load capacity derived from strength class 70, with the lower rating reflecting the nut's low-profile design.
