cromox® NAUTIC shackles made of stainless steel (inox) – robustness and design in perfection

The shackle is an indispensable part on any boat. It connects two elements safely and reliably: for example,as anchor shackle the anchor with the anchor chain. A shackle must therefore be 100% reliable - this is where Ketten Wälder scores with its choice of material. The stainless steel (AISI 318LN Duplex), also called inox steel (from French "inoxydable", in English "inoxydable" or "non-corrosive"), ensures the long durability of the product through temperature and corrosion resistance even in salty waters.

Stainless steel nautical shackle: safety paired with attractive design

Due to its special design, the pin of our cromox® NAUTIC shackle is doubly secured against accidental loosening. In the secured state, it can be rotated, which enables a flexible and at the same time reliable connection between two elements. Visually, the shackle convinces with its appealing and high-quality design.

Doubly safe due to shackle quick-release fastener and safety catch

One area of pin and shackle design that is particularly important to the safety of the product is the quick-release fasteners and securing systems. These systems are designed to have a double safety feature, which means that they provide additional protection against failure. First of all, the shackle quick-release plays a role here, allowing the bolt to be attached and also detached quickly and easily. The shackle lock provides an additional layer of security by ensuring that the pin cannot be accidentally released. This dual securing feature provides a number of benefits: First, it increases the overall safety of the structure by reducing the risk of bolt failure; second, it allows for faster and more efficient assembly and disassembly by making the bolt easy to attach and detach; and third, it provides an additional layer of safety by preventing the bolt from being accidentally detached.

The importance of corrosion resistance in the marine industry

Corrosion resistance is one of the most important properties for materials used in demanding environments such as marine applications. High corrosion resistance means that a material is able to resist attack from moisture, seawater and other corrosive substances and maintain its structure and function over time. One material known for its excellent corrosion resistance is stainless steel. Stainless steels are a category of steels that contain at least 10.5% chromium and often include other elements such as nickel, molybdenum and titanium. The excellent corrosion resistance of stainless steel is due to the formation of an extremely thin and stable chromium oxide layer on the surface of the material. This layer isolates the material from the environment and prevents corrosive substances from entering the material. The use of high-quality stainless steels can therefore help to extend the service life of devices and equipment, reduce maintenance and repair costs, and improve safety and reliability.


What are nautical shackles?

Nautical shackles are special fasteners used mainly in shipping. They are used to connect ropes, chains or wire ropes. The shackles for boats, ships and yachts are made of durable material, usually stainless steel, to withstand the sometimes extreme conditions at sea. Nautical shackles are usually U- or D-shaped, with a screw or pin fastener attached to the end. They come in various sizes and designs, depending on the purposes and loads for which they are needed.

Where are nautical shackles used?

Nautical shackles are mainly used in water sports and shipping. They are used for quick and safe connection of ropes, ropes or chains. They are used in sailing, on boats, yachts and ships of all kinds. They are an important part of the rigging and are used, for example, to fasten the sails to the mast or boom. Likewise, they are used in the anchor chain or when mooring the ship in port. Thanks to their high load capacity and corrosion resistance, they are ideal for use in the maritime environment.

What is special about the Nautical Shackles from Ketten Wälder?

The pin of the cromox® NAUTIC shackle from Ketten Wälder is doubly secured against accidental loosening by a special design. When secured, however, it can be rotated, which enables a flexible and at the same time secure connection between the two connected elements. Its blasted surface and the AISI 318LN Duplex stainless steel used additionally increase corrosion resistance and thus also safety and service life.

What are the advantages of stainless steel shackles?

Stainless steel shackles have several advantages:

  1. resistance to rust, corrosion, wear and high/low temperature
  2. high load capacity for heavy loads
  3. durability
  4. easy maintenance
  5. modern, clean look
