I am having difficulties starting the lead screws. Any suggestions?

As you noted in your email.

The supplied ACME nuts are: 3/8-10 (2- Start).

Apparently I'm a slow kid, as I can't get mine to thread either. If you were ordering rod from McMaster-Carr, what product number might you use?

Thanks,

Slow kid gets smart... I believe I found the 2 Start Screws at McMaster-Carr:

McMaster-Carr Part Number: 99030A315

Sadly I pre-ordered my ACME Screws in single start:

McMaster-Carr Part Number: 93410A608

Ultimately I think it'll be cheaper to buy new anti-backlash leadnuts than new screws.

All screwed up,

We now sell the ACME Lead screws:

We're also working to make all of our items available, and also to restructure the shipping program to offer more (cheaper) options for shipping.

sed8me - The part number you listed is for a 3/8"-8, 2 start and you need a 3/8"-10, 2 start.
The part number I got was 98940A613 and it worked in the nut just fine, possibly a little tight, but I think that is OK.
