This low-profile hex nut is manufactured to DIN 936 standards and made from steel with an electro-galvanized finish, making it well-suited for indoor use or applications with very mild environmental exposure. It carries a hardness class of 14H, indicating a minimum hardness of 140 HV—note that no proof load is specified for this class. The nut features a metric thread with a left-hand (LH) direction, which is typically used on components that rotate clockwise to help prevent loosening during operation.
