About Nuweld

Nuweld Trade Supplies is a family-owned market leader in heavy-duty engineering clamps operating across Australia and New Zealand. We have been manufacturing our heavy-duty high-quality engineering clamps in Auckland, New Zealand since the 1950’s.  Our story began 60 years ago when a demand arose in the heavy engineering and welding industry for a robust and reliable clamping device that puts safety first and was able to go the distance. With some kiwi ingenuity and a “can do” attitude the Nuweld heavy-duty clamp was born.

We have continued to make these high-quality clamps since then, staying true to the original recipe. Today we are a market leader in the manufacture of heavy-duty engineering clamps and Acme threads. Our products are used throughout Australia and New Zealand by industry professionals as well as leading industrial and engineering firms. Our clamps are renowned for their high performance and high quality and are built to last a lifetime!

Our ethos is to make the best all steel clamps and Acme threads, from our workshop in New Zealand to yours!

Nuweld Clamps are manufactured to the highest standards and severely tested for strength, to exceed the highest of expectations. Made for use in heavy engineering applications with safety in mind, Nuweld Clamps are constructed to perform under the harshest conditions and are made to last, providing exceptional value for money. All our clamps come with a 100% lifetime guarantee!



Our G Clamps and Welding clamps are used in the Mining, Steel Fabrication, Ship Building, Structural Engineering, Construction, Boiler Making, Carpentry, Petroleum, Agriculture, Motor Manufacture and Trucking Industries or wherever there is a need to securely clamp high strength heavy parts under extreme pressure.


Our Acme threads are most often used for lead screws, jack screws, CNC systems and many other applications. Also used in industrial applications requiring heavy torque and power transmission such as lathes, milling machines and presses. Acme threads, with a 29-degree angle, are broader, stronger, and squarer than standard V-shaped threads. This makes them the best choice for power transmission and carrying loads.
