DIN 933 12.9 zinc Bolt with hexagonal head and full thread

Overview

DIN 933 12.9 Hexagon head bolts with full thread are high-performance fasteners characterized by a hexagonal head and a thread that runs from the base of the head to the end. It is usually made of high-strength carbon steel, which gives it increased resistance to loads and deformation. The strength class 12.9 indicates its ability to withstand significant mechanical loads, making it an ideal choice for critical structures and demanding applications where high reliability and durability are required.
