The Pen Assembly Press allows you to press pen parts together fast, reliably, and with all the power you need. This press features a screw thread style rod that provides virtually infinite rod positioning. A rear spring acts as your 3rd hand and positions the rod where you need it. A locking lever then securely locks the rod in place along the threads. The spring loaded ram micro-adjusts to any pressure variations while you position the rod. Your parts will stay firmly in place while the 300lb pressure toggle clamp firmly and accurately presses your parts together. Presses parts from 1" to over 7".
