Bolt DIN 931 M16x30 5,8 zinc

Overview

The DIN 931 bolt has a hexagonal head and partial thread, making it a versatile solution for a variety of applications. The partial thread only covers a certain section of the shaft, leaving a smooth section to ensure strength and stability of the connection. The strength class of these bolts is 5.8, which indicates their sufficient reliability for many structural tasks. Diameters range from M6 to M36, with a standard thread pitch that meets metric requirements. DIN 931 bolts are particularly suitable for use in areas where friction must be reduced and easy access to the thread is required, making them ideal for applications in mechanical engineering and construction.
