V-Jaws (3-9mm diameter) - nickel-plated having a hardened steel surface of 1.2mm pitch teeth to create a V-shaped groove. For round samples where flat jaws do not provide enough surface contact (e.g. wires, rods, tubes). Supplied as 0.5 set = 2 jaws (left & right). Order any combination of 2 half sets of jaws to fit into a pair of MecS622 Wedge Grips (upper & lower).
