Measuring 10 mm high and utilizing 1/2–13 cam screw, Series-9 clamps are manufactured so each clamping surface is 1 mm greater in distance from centerline then previous surface. By rotating hex, clamps can hold parts that vary up to 6 mm. Clamps come in 4 different sizes for total adjustment of 24 mm without changing to different hole location. Available with smooth or serrated clamping edges, heat treated hexes are suited for clamping castings and rough cut stock.
