Left-hand threaded fine thread hex nuts according to DIN 934 standard, property class 8. Left-hand threads are used in applications where rotation or operating torque could otherwise loosen a standard right-hand threaded nut, for example in rotating tools where the direction of rotation instead contributes to tightening. The fine thread provides increased thread engagement per unit length and allows more controlled tightening. This category includes both plain and zinc plated options. The range from SWEBOLT & BOTNIA BOLT focuses on robust solutions for secure and reliable fastening.
