Torque

What is Torque?

Torque is a small, free web page that makes metric screws, nuts and washers from M2 to M20, using an ISO dimension table for each size. You pick a preset size or a custom one and set the screw length. Heads come as socket cap, button, countersunk, pan or headless, with no drive or a hex socket, and the thread can be coarse, fine, a custom pitch or smooth. Nuts have a height and a clearance setting, and washers a thickness.

The nut thread is the screw thread plus that clearance, 0.2 mm by default, so a pair always mates. A clearance test kit prints a short screw and three nuts at 0.1 mm less, the current value and 0.1 mm more, so you can find the fit your printer gives and type it in. The page says pairs print reliably on FDM printers from M6 up, since finer threads are too small for a typical nozzle.

You download the screw, the nut or the washer as a binary STL, or all three together. Screws are exported head down, ready to print. Settings are kept in the URL, so a link restores a configuration. It is free, needs no account, works offline and has six interface languages. The code is public on GitHub, but the repository has no license file.
