Bolt DIN 933/931 M8 x 75mm

Hot-dip galvanized fasteners are designed for both indoor and outdoor use. Hot-dip galvanized bolts do not rust and retain joint strength when exposed to rain, snow or flooding with water. Technical features of fasteners to DIN 931 Partially threaded metric bolts manufactured in accordance with the requirements of DIN 931 have threads of product grade A (M1,6-M36 up to 150 mm long) and B (M24 –M 160 over 150 mm long). They are among the most common fasteners in construction, mechanical engineering and manufacturing. They are used to create a rigid threaded joint characterized by high reliability and strength. Bolts to DIN 931 are designed for fastening metal, wooden and other parts of complex structures and for fixing individual parts to solid bases with holes of a suitable diameter. Nuts, washers, bushings and lock nuts are used for fastening with such fasteners. Either the bolt itself or the fixing nut can be tightened with spanners or sockets of the appropriate size. For use in different fields of activity, bolts to DIN 931 differ: By material. The most common are fasteners made of carbon steel (35, 20, 10, 20кп, 10кп). Bolts can also be made of stainless steel. By coating. Electro-galvanized (Zp) and hot-dip galvanized (ГО/HDG) coatings are available. Thermal diffusion galvanizing (ТДЦ) is also used. By size. Fasteners are produced with nominal diameters from M1,6 to M160; By strength. The following bolt property classes are available: 12.9; 10,9; 8,8; 5,8; By thread type: fine/coarse. Application of bolts to DIN 931 Hexagon head bolts with full or partial thread are universal fasteners. Depending on the manufacturing specifics, size and thread type, the fasteners are used: In mechanical engineering for joining elements of machines, machine tools and equipment; In furniture manufacturing for fixing carcasses, fronts and fittings; In the road sector (fastening of guardrail and structural elements); In agriculture (joining ploughshares and ploughs, mounting attached implements); For the assembly/maintenance of bucket elevators and conveyors; In construction for the assembly of enclosing structures, etc. Advantages of bolts to DIN 931 Versatility of application in different fields of activity; Reliable fixing (complete with nuts and washers); Resistance to corrosion and acids, especially for stainless steel products and steel products with an HDG coating (hot-dip galvanized). The M10 bolt manufactured to the DIN 931 standard is a fastener with a hexagonal head. The nominal thread diameter is 10 mm. It is used as a fastener in the assembly of various compact-sized products. Available with zinc-plated and hot-dip galvanized coatings.
