Fine thread hex nut according to DIN 934 standard, property class 12, plain (uncoated). The fine thread provides increased thread engagement per unit length and enables highly controlled tightening compared to coarse thread. This makes the nut suitable for applications with vibration or where precise tightening is required. Property class 12 is used in applications with very high requirements for clamping force and load capacity. The plain surface is intended for dry environments. Used together with fine threaded bolts or screws of corresponding property class. Available in multiple sizes from SWEBOLT & BOTNIA BOLT.
