These might seem such an ordinary item but when it comes to moving or shipping a turntable, they absolutely MUST be "locked down" and if possible, the platter removed
So often a new turntable is received, hopefully with transportation bolts in place, then the bolts are removed when setting up the turntable and from that time on the bolts go "missing in action" having been lost or thrown out.
These bolts came from a "parted out" C.D.C ST 510 but it is very likely they will suit use with other turntables

21mm of the lower bolt shaft is threaded - I do not know what the thread type is although I would make a guess at it being a metric thread
