Frequently asked questions
Will it fit a 10mm threaded rod?
No. This nut is sized for 8 mm threaded rod. A 10 mm rod typically needs a matching M10 nut.
Should I use an anti-backlash nut for motion?
The threaded rod listings recommend anti-backlash nuts for movement screws. This standard hex nut is a general-purpose nut suited to frames and fastening.
