Wooden handscrew clamps have two independently adjustable jaws controlled by two separate screws, allowing the jaws to be angled to grip tapered or irregular shapes. Bar and pipe clamps have parallel jaws that can only apply pressure to flat, parallel surfaces. The wooden jaws of a handscrew also protect delicate or finished surfaces from denting.

We carry Dubuque Handscrew Clamps in multiple sizes. Check the product listing for current size options and jaw opening capacities, as these are the standard sizes used for furniture and cabinetmaking applications.

Yes. This is one of the primary advantages of the handscrew clamp. By adjusting the two screws independently, you can splay or converge the jaws to match the angle of a miter or taper and still apply even clamping pressure across the joint face.

Yes. The hardwood jaw faces of a handscrew clamp are much gentler on finished or softwood surfaces than metal clamp pads. You can clamp directly to a finished surface without leaving dents or marks in most cases, though a scrap-wood caul between the jaw and a very delicate finish is always a safe precaution.

To open the clamp, hold both handles and rotate them simultaneously away from you (like turning two bicycle pedals forward). To close and apply clamping pressure, rotate them toward you. For angled clamping, adjust the front screw to set the angle of the jaw opening before tightening the rear screw to apply final pressure.

Yes. Woodworkers often clamp one jaw of a handscrew into a bench vise to create a quick holddown or angled clamping fixture. They can also be used with one jaw hooked over the edge of a bench top as a simple work stop. Their versatility extends well beyond conventional glue-up clamping.
