Our story

Dutyhook started activities 1996 providing managment services. Dutyhook has been constructing amphibious vehicles from 2004 as new project and lifetime dream of the founder Mait Nilson. Latest build Amphibear crossed 760 km St Louis, Senegal - Praia, Santiago Island, Cape Verde on Atlantic Ocean December 2013. You can find the full story at

During construction and building of amphibious vehicles it become obvious, how little information is provided about fasteners and chandlery products and how it makes almost impossible to find the right ones. e-shop is natural response to that, providing a lot of detailed information to ease all DIY enthusiasts projects.

Dutyhook is derivation from heavy duty hook, but means we take our duty of providing fasteners seriously.

Dutyhook service feedback you can read in Dutyhook Amazon Store.

Have a nice shopping experience and good luck for your project!
