The DIN 439 half hex nut is a low-profile, six-sided fastener made from A2 (Grade 304) stainless steel, offering good corrosion resistance. Its main purpose is to serve as a lock nut (jam nut) in conjunction with a full nut to prevent loosening, or for use in applications with limited vertical space.
