The head will have grade markings. If there’s no markings it usually low grade / soft. Just because it’s stainless doesn’t make it stronger.I took apart the Bass clarinet stand I recently bought and the pivot bolt for the upright is a black machine bolt threaded from the base of the head to the end. It is basicly a new stand and the bolt already shows wear from where the upright comes in contact with it when it pivotes. I belive the bolt is a very mild / soft steel and the upright a much harder quality of steel that wears it away on contact. Threads were already worried through.
I will replace this bolt with a shouldered stainless steel bolt. Should last a life time.
