No they will be correct, they are twin start screws. If you look carefully at the end you will see multiple threads, but it's easy to check just rotate the ballnut and measure how far it moves.

It's a common mistake.

The reason they use this method is it gives higher torque and lessens the depth required and keeps the screw stronger.

Omg I will be so happy when confirming this. I believe you and Andy. It really sucked out all my energy when measuring today. Now I have hope again!

I have also received following parts:
- 4x DMM 400w servo motors and drives. One is with a brake.
- ATC spindle from Jianken, 3.2kW with BT30 interface, sunfar E550 VFD, Waterpump and 100mm spindle bracket.
- Aluminium tooling plates from Germany.
- Ethernet SmoothStepper combined with MB3 breakout board.
- 1000mm straight edge DIN 874/2 and 300x200 square DIN875/1 from Helios Preisser.
- 20mm linear rails, 1605 and 2010 ballscrews, cable dragchains from BSTmotion.

I am still waiting for aluminium profiles and HTD pulleys.

I will post some pictures soon to show you guys all the hardware.

99.9999% Sure they will be correct. I did exactly the same first time I came across them so yes I know that feeling you felt.!
