Torque Specs for Bolts/Screws

    Does anyone know what torque should be applied to the screws when assembling these v-slot parts? I have some 45mm motor mounting bolts(m3)... some m5 tee nuts about 10mm... etc I know this may be a strange question but I paid all this money for a torque wrench so might as well use it and have all those parts locked tight together on the frames and motors.

    That's a good question Dude and I am not completely sure of the answer, but I am interested if you are able to find out. It would be nice to pass it along if someone else has this question down the road.

    Thanks Al

    Are the tee nuts steel? Are these torque ratings the max for the screws? Isn't there going to be deformation of the aluminum if you overtighten steel screws? Some of the screws go directly into the aluminium so they may strip if overtightened...

    Valid points.

    IMO it's more likely you would strip threads by over torque than to deform the extrusion. YMMV.

    Thank you! That's awesome. I'll post the data here in case that site goes down. Screw Torque ratings.jpg
