Description Lock nuts manufactured from A2 stainless steel to Din 439, featuring a reduced thickness design for use where space is limited or where a secondary locking nut is required. Commonly referred to as a jam nut, the Din 439 pattern is designed to be tightened against a standard nut to help prevent loosening. A2 stainless steel provides good corrosion resistance for general purpose internal and external applications.
