A Comprehensive Guide for Tie Down Hooks
Tie down hooks play a very important role in maintaining the stability of cargo, distributing the weight of cargo, and maintaining the balance of the vehicle. Especially when you are transporting heavy cargo or irregularly shaped items, proper securement can avoid accidents caused by cargo shifting.
What are Tie Down Hooks?
Tie down hooks are the essential tools used to secure the cargo during transportation. They are mainly made of metal materials, such as carbon steel, stainless steel, etc. The tie down strap hooks always work with the anchor straps, chains, or ropes, providing a strong connection between the cargo and trucks, trailers, ships, or other modes of conveyance.
Metal S Hook
Metal S hook can be also named an S hook tie-down. This is one of the most commonly used types of tie down hooks, due to its efficient design and ease of use. As the name suggests, this hook shape looks like an “S“, made from durable materials such as steel or stainless steel, ensuring high tensile strength and resistance to corrosion. One end features a closed hook that needs to be attached to the strap, and the other end is open for easy attachment to anchor points.
Application of Metal S Hooks
S hook tie-downs are versatile, and you can see from many applications, including:
Light to Medium-Duty Hauling: S hooks are perfect for securing lightweight to medium-weight cargo. Such as household moves, DIY projects, and transporting everyday items like furniture, bicycles, and small machinery.
Camping and Outdoor Gear: S hooks are also a very convenient tool for outdoor trips. Such as they can used for tents, sleeping bags, camping chairs to roof racks, or inside a vehicle.
