Standard:DIN6340
Description:
The DIN 6340 Washer, also known as a Zinc Plated Washer, is a type of fastener commonly used in various industries and applications. It is designed to distribute the load of a threaded fastener such as a bolt or screw and prevent damage to the surface being fastened.
The DIN 6340 Washer is manufactured according to the specifications outlined in the German Industrial Standard (DIN) 6340. This standard ensures that the washer meets specific requirements for its dimensions, material, and performance.
The Zinc Plated Washer refers to the surface treatment applied to the washer. Zinc plating provides a layer of corrosion resistance, which helps protect the washer from rust and other forms of degradation. This makes the washer suitable for use in both indoor and outdoor environments, where moisture or exposure to the elements may be a concern.
The M6-M30 designation refers to the size range of the DIN 6340 Washer. The "M" stands for metric, indicating that the washer is designed to be used with metric-sized fasteners. The numbers following the "M" represent the diameter of the bolt or screw that the washer is compatible with. In this case, the washer is compatible with fasteners ranging from M6 (6mm in diameter) to M30 (30mm in diameter).
Overall, the DIN 6340 Washer/Zinc Plated Washer is a versatile and widely used fastener that provides support, load distribution, and corrosion resistance in various applications where metric-sized fasteners are used.
