Why To Never Buy Chinese Sh*t

I had a set of crane roller rockers that I over torqued and they snapped, crane had no data on the tightness. I later found out the torque is only supposed to be around 20 ft lbs. The material used in these things I guess is very hard and brittle and will not take high amounts of torque to snap.

In any event, learn from me, replace them - be carefull on the lock nut torque !
