Bolt DIN 931 M16x120 5,6 zinc

Overview

The DIN 931 bolt features a hexagonal head and partial metric thread, making it a versatile solution for many design tasks. The threaded portion of the shank provides a secure connection, while the smooth portion allows the bolt to be used as an axial support or to reduce friction in mechanisms. The strength class is usually 5.6, which indicates sufficient strength for light and medium load applications. The bolt diameter can vary from M6 to M36, depending on the project requirements, and the thread pitch complies with metric thread standards. DIN 931 bolts are often used in mechanical engineering, construction and other industries where reliability and ease of installation are important.
