Fine thread hex nut according to DIN 934 standard, property class 8, plain (uncoated). The fine thread provides increased thread engagement per unit length and allows more controlled tightening compared to coarse thread. This makes the nut suitable for applications with vibration, where precise adjustment is required, or where available thread length is limited. The plain surface is intended for dry environments or applications where no surface protection is required. Used together with fine threaded bolts or screws of corresponding property class. Available in multiple sizes from SWEBOLT & BOTNIA BOLT.
