cromox® stainless steel NAUTIC shackle (inox) – designed to be robust

The shackle is an essential component to any boat. It connects two components safely and reliably: For example, it connects the anchor to the anchor chain safely and securely. A shackle must therefore be 100% reliable – this is where Ketten Wälder scores with its choice of materials and design. The stainless steel (AISI 318LN Duplex), also known as inox steel is corrosive resistant and rust free. This ensures the product's long service life in salt water, warm or cold.

Doubly secure thanks to shackle quick-release fastener and safety catch

One area of the design of bolts and shackles that is particularly important for the safety of the product is the quick-release fasteners and safety systems. These failure protection system is designed to have a double safety feature. Firstly, the quick release element allows the bolt to be attached and detached quickly and easily. Secondly, the shackle lock provides an additional layer of security by ensuring that the pin cannot be accidentally released.

This double lock offers a number of benefits: Firstly, it increases the overall safety of the structure as it reduces the risk of the bolt failure; secondly, it allows for quicker and more efficient assembly and disassembly as the bolt can be easily attached and detached; and thirdly, it provides an additional layer of safety by preventing the bolt from being accidentally released.

The importance of corrosion resistance in shipping

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 can withstand attack from moisture, seawater and other corrosive substances and maintain its structure and functionality over an extended period of time.

One material that is 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 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 protects the material from the environment and prevents corrosive substances from penetrating the surface of the product. The use of high-quality stainless steel can therefore help to extend the service life the equipment, reduce maintenance and repair costs and improve safety and reliability.


What are nautical shackles?

Nautical shackles are special connecting components that are mainly used in shipping. They are used to connect ropes, chains or wire ropes together. The nautical shackles for boats, ships and yachts is made of corrosive resistant stainless steel withstand extreme conditions at sea.

Nautical shackles have a U shape with a screw or bolt fastener at the end. They are available in different sizes with a WLL capacity up to 6 tonnes.

Where can nautical shackles be used?

Nautical shackles are mainly used in water sports and boating environments. They are used to quickly and securely connect ropes, cables or chains. They are used for sailing, on boats, yachts and vessels of all kinds.

They are an important part of the rigging and are used, for example, to attach sails to the mast or boom. They are also used in the anchor chain or for mooring the vessel.

Thanks to their high load-bearing capacity and corrosion resistance, they are ideal for use in a maritime environment.

What is special about the Ketten Wälder nautical shackle?

The pin of the cromox® NAUTIC shackle from Ketten Wälder is doubly secured against loosening thanks to a special design.

When secured, however, it can be rotated, which enables a flexible and secure connection between the two connected elements. Its shot blasted surface and the AISI 318LN Duplex stainless steel used increases its corrosion resistance and therefore also its safety and service life.

What are the advantages of stainless steel shackles?

Shackles made of stainless steel have several advantages:

  1. Resistance to rust, corrosion, wear and high/low temperatures
  2. High load capacity for heavy loads
  3. Durability
  4. Easy to clean
  5. Modern, clean look
