Bolt DIN 933 M12x40 12,9

Review

DIN 933 12.9 Hexagon head bolt with full thread is a high-performance fastener characterised by a hexagon head and a thread that runs from the base of the head to the end. It is usually made of high-strength 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.
