DIN 935-1:2013 Coarse Thread Fine Thread Metric Hexagon Slotted Nut

DIN 935-1:2013 Metric Slotted Hex Nut with coarse and fine thread options has slots at the top for use with cotter pins or similar locking elements. The available thread forms cover different assembly needs and are suitable for connections requiring reliable mechanical retention.

This product is commonly used in vehicle chassis, shaft-end fixing, rotating mechanical parts, agricultural equipment, and safety-related joints. The slotted design allows a pin to be installed after tightening, providing visible anti-rotation security.

Materials and corrosion-protection finishes can be selected according to load class, thread form, and service environment to meet requirements for maintainability and long-term reliability.
