We’ve started shipping with nylock nuts. For most folks, this won’t make a huge difference, but it does add a level of security from having the M3 nuts back off over time, especially if you use your Mill One all the time. We try to keep finding ways to improve our products, of course, even if they’re small changes!
If you want to get an Anti Backlash Nut Kit, use the coupon code “10ABL” at checkout to get $10USD off the kit. The code will work until Nov 30!
