Reinforced spring for New K03 Single Clamp (In stock)

Extra spring thickness significantly reduces the vertical movement of the clamp. The springs are intended for high load operation (e.g. rough work on hard steels). Material: steel 65G polished, hardened;  Thickness: 1mm (standard is 0.8mm);  Maximum load on abrasive: 1kg (standard is 0.5kg)   *** Important ***  Please write in order comment whether you have the old steel fixing unit (Pre-Dec 2017) or the one-piece fixing unit.  They take different springs and are not interchangeable. Due to extremely low cost vs. cost of shipping, these are non-returnable, non-refundable. We apologize for the inconvenience.
