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, alloy-based, etc., these are made to last and withstand heavy loads without bending. I have paid $110 for them. Price is $60 + shipping.
