Din 439 Lock Nut / Thin Nut

The DIN 439 standard defines the dimensions and characteristics of hexagon thin nuts, commonly known as lock nuts. These nuts are designed to be thinner than standard hex nuts, making them ideal for applications where space is limited or when used as jam nuts to prevent loosening. The compact design of DIN 439 hexagon thin nuts provides an efficient fastening solution, particularly in situations where a lower profile nut is necessary. By adhering to the specifications outlined in DIN 439, these nuts ensure reliable performance and secure connections in various engineering and mechanical applications.
