Description Lock nuts manufactured from A4 stainless steel to Din 439, featuring a reduced thickness design for use where space is limited or where a secondary locking nut is required. Also known as jam nuts, Din 439 lock nuts are tightened against a standard hex nut to help resist loosening. A4 stainless steel offers excellent corrosion resistance, making these nuts suitable for use in demanding and aggressive environments.
