Frequently asked questions
Which nut should I use with this screw?
Use an M6 nut with the standard coarse pitch of 1.0 mm, or an M6 T-nut or slot nut when fixing into aluminum profile slots.
Will it fit aluminum profile slots?
The M6 thread works with M6 slot nuts or T-nuts, but you should confirm that your profile's slot width accepts the nut you plan to use.
