Abstract: A device and method are provided for marking bolt holes in sill boards. The marking device includes a rectangular, substantially planar member having a first end and a second end. One or both ends are configured to receive an anchor bolt. A first punch is positioned a first distance between the ends of the marking device such that the punch is aligned with each end of the marking device. The punch is preferably connected to the planar member by a securing member such that the punch is perpendicular to a face of the planar member. The punch is preferably adjustable. Optionally, a second punch is connected to the planar member. One or both ends may include a tortured slot to receive anchor bolts having a number of diameters.
