What Size are Laser mount bolts

what size are the bolt to mount the laser? I have one that is a 1/4 inch too short

From here, it looks like an M5 x 30mm. I would use a locknut instead though.

Come to think of it, the math doesn’t add up. Those plates are at least 3mm each. Add the 2.5mm or so spacing between plates and the aluminum extrusion and the extrusion itself gives (3 * 2) + (2.5 * 2) + 20 or 31mm. The bolt should be at least 35mm.

maybe ust take a good one to your hardware store :slight_smile:

I dismounted it and tightened all the bolts and now it fits. Thanks all
