This Wilton® Machinist Bench Vises is designed to handle the most demanding clamping applications. Unlike most vises that have a fixed center nut, this vise is anchored at the rear to provide straight line pull and even pressure, resulting in greater durability. Round channel design allows for a completely enclosed spindle and nut assembly which keeps debris out and lubrication in. Locking swivel base features 360° rotation that is enhanced by a serrated swivel base with double lockdowns for non-slip clamping. Equipped with high-strength steel replaceable main jaws and a machined, large anvil work surface. Available in 5in. or 6in. jaw width. Limited lifetime warranty.
