Rockler's Pock-It Hole Clamp ($20) is a novel device for aligning and clamping pocket screw joints in 3/4-inch stock up to 3 inches wide. A plastic pin engages the pocket hole and draws the stock up flush to the bottom of the aluminum clamp body. To use the tool on a flat assembly table, you pull out the clamping knob to disengage it while snugging the clamp with a hex bit driver. Clearance under the clamp frame lets you fasten pocket screws as close as 1/2 inch to each other while the clamp is engaged. 800-279-4441, www.rockler.com.
