DIN 931 10,9 Delta Hexagonal head bolt with partial thread

Overview

The DIN 931 bolt has a hexagonal head and partial thread, making it extremely practical in many structural applications. This type of bolt, with a strength class of 10.9, provides high resistance to loads and deformation, which is critical in mechanical systems. The partial thread reduces friction during tightening and ensures a secure connection. Diameters range from M6 to M36, allowing them to be used in a variety of projects. DIN 931 bolts are the ideal choice for structures where a smooth shaft is important, such as for axles or in places where excessive friction must be avoided.
