The Stanley 6-MR77 Hand Riveting Press is an essential tool for constructing assemblies and repair projects. It is constructed with a sturdy steel frame and a swivel head that allows for precise placement of the rivet along with accuracy on a heavier constructed frame. It has a maximum reach of 2mm, 3mm, 4mm, and 5mm and is ideal for use with soft and hard steel, brass, aluminum, and copper rivets. The hand-operated lever allows for the same performance as an air powered riveter with the same cupped rivet design. It is lightweight, easy to handle, and offers the convenience of 5 different sizes of rivet selection.
