Significantly expand the versatility of your Swanstrom parallel-action heavy-duty bail-forming pliers (available separately) with this specially designed set of round jaws from Swanstrom. Each jaw in this 10-piece set is ideal for forming jump rings, S-hook clasps, loops, bails and any findings that require a smooth, even loop. Together with the five sizes included with your pliers, this set equips your bench with a total of 15 jaw sizes—100 possible combinations that are ideal for creating an endless variety of findings. The jaws are crafted from hardened tool steel that ensures a long life; easily change jaw sizes, securing them to your pliers with the hex screw and Allen wrench that came with your original pliers. The set includes a Delrin® organizer block (101 x 39 x 10mm) clearly marked with the jaw sizes, making it quick and efficient to select the size you need.
