These are audiophile custom machined out of solid stainless steel. Thread is M8 for many European floor-standing speakers. Come with adjustment nut and washers also made out of stainless steel.They are not audio jewelry like many that you see gold plated, etc., these are made to last and withstand heavy loads without bending. Price is $60 + shipping. I have paid $110 for them.
My loss is your gain.
