Bolt DIN 931 M30x110 8,8 zinc hot

Overview

The DIN 931 bolt has a hexagonal head and a partial metric thread that covers only a certain part of the shaft, while the rest of it remains smooth. This type of bolt is usually manufactured with a strength class of 8.8, which ensures high reliability and durability under load conditions. Diameters range from M6 to M36, with the possibility of manufacturing in other sizes that comply with metric thread standards. DIN 931 bolts are ideal for applications where it is important to reduce friction or provide a clean surface for mounting, such as in structures that require precise alignment or load distribution. Hot-dip galvanizing provides additional corrosion protection, making these bolts particularly suitable for outdoor use.
