A method, computer program and system for joining two tables, t1 and t2 are described. The apparatus includes a cam bolt having an internal cam feature and external cam feature that together allow for increased range of adjustment. Optionally the space can be defined by a disposable plastics tube, with a closed end, so that a defined length of the tool is magnetized. Thereafter, first work function metals are deposited in the NMOS opening and second work function metals are applied in the PMOS openings.
