Open end insert tool OE series

Like all Sturtevant Richmont, interchangeable heads our open-end series consists of one piece, cast heads that are made from a proprietary metal formula. The rounded corners distribute the stress vectors so they don't all intersect at one point and create breakage. The same applies to the U-bottom design. The rounded bottom distributes the stress vectors and that improves durability. Our heads all come with a torque rating clearly shown on the head. Remember: ALL of our heads fit on ALL of our wrenches. Less inventory to carry Fewer tools to calibrate Fewer spares required Lowest cost of ownership because of the durability
