DIN 934:1987 Coarse Thread Fine Thread Metric Hex Nut

DIN 934:1987 Metric Hex Nut covers both coarse and fine thread options and is one of the most widely used standard nuts for general mechanical fastening. The hex profile allows easy wrench engagement and pairs with bolts, studs, and threaded rods to form removable threaded joints.

Coarse threads support efficient assembly for standard connections, while fine threads offer advantages in adjustment precision, resistance to loosening, and use with thinner components. This nut is suitable for machinery manufacturing, equipment installation, steel structures, vehicle maintenance, and hardware assembly.

Different strength classes, materials, and surface finishes can be selected according to service conditions to meet requirements for corrosion protection, appearance consistency, and stable mass assembly.
