Acme Thread & Barrel Nuts

For movement under large loads Nuweld acme threads are precision machined and produced from AISI 1215 Low Carbon Bright steel. Acme screws have much better wear properties, load capabilities and tolerances than standard threaded rods. With thicker and wider threads acme rods also operate better in environments with dirt and debris.

From our happy customers

Nuweld make a great clamp. I have been using them in my workshop for decades and always buy from them.

Terry C.

I came across these clamps on the web looking at HD clamps. I already have a few clamps, but none are like these, they are great!

Antonio H.

The Nuweld Earth clamps are excellent. I purchased one to use on my welder to replace the old crocodile clamp and installed it on the earth cable. The clamp provides excellent earthing and a secure fixing.

Warren G

I bought a barrel nut for a restoration project from this website as there was nothing over here in the UK and the only alternative was to get one made specially. Nut arrived safe and well! Thank you for a superb service and your concern.


These clamps are truly heavy duty, and could feel the quality as soon as I held them. The acme thread used on these clamps is very smooth and robust. Takes only a few turns to tighten up the clamps due to the pitch.

JP Engineering

We ordered the wrong size clamps. Jith from NTS was quick to help us get the correct sized clamps and refunded the price difference. Great service and excellent product, the clamps work perfectly!

Riton Engineering

Excellent quality and very robust clamps with a good quality finish. Capable of producing significant force without any distortion.

Michael Johnson

Good value solid general purpose clamps use for woodworking, welding and other engineering. Every bit as good as the big name brands.

DML Engineering

Excellent quality, great price and next day delivery what more could anyone want. Truly Heavy duty unlike other clamps I have had from mainstream DIY retail outlets.
