Bolt DIN 931 M39x140 10,9

Overview

The DIN 931 bolt features a hexagonal head and partial metric threading that covers only a specific section of the shank, leaving the rest smooth. This type of bolt is often manufactured in strength class 10.9, which provides high resistance to mechanical loads. Bolt diameters can range from M6 to M36 and above, in accordance with metric thread standards. DIN 931 bolts are ideal for applications where it is important to have a smooth part of the shank to reduce friction or provide support. They are used in various industries, including automotive, mechanical engineering and construction, due to their reliability and strength.
