The bolts for the feet and where they thread into the stool are soft metal (held by plastic in the legs) and most likely assembled without ever being fitted. This tends to cause the plastic holding the bolt end of the leg to crack, and the metal to strip and flatten because they dont thread together easily. If you want the best fit, use a tap and die on each leg and thread (M8x1.25). They will go together butter smooth after that with no cracking. Adding thread lock gel will give you a final, sturdy, stool.
Youll need to do this for a good fit
