Tru-Center™ Toggle Products Adjustable Torque Toggle Screws The Jergens patented “Tru-Center” products are the only pad type on the market to provide true center line clamping. The cut-away drawing illustrates how this works. The center line of the pad and the center line of the nut always intersect at the point of contact between the pad and the workpiece. Perfect for delicate and ne clamping. Once the end holding force is reached, the head breaks free. Larger radius, straight knurled head for easy turning. • Material: Stem, Stressproof® Pad, 4140 Head, Cast Iron • Finish: Stem, Black Oxide Pad, Zinc Plate Head, Cadnium Plate • Thread: 2A-UNC • Pad: Angular movement either side of center (total 16°) For clamping of irregular surfaces while the swivel shoe prevents marring of polished surfaces. Shoe is hardened for longer life. The cast iron hand knob is included for hand tightening. To remove pad for installation, pull and turn counter-clockwise. • Material: Stem, Stressproof® Pad, 4140 • Finish: Stem, Black Oxide Head, Chrome Plate • Thread: 2A-UNC • Pad: Angular movement either side of center (total 16°) Hand Knob Toggle Screws Part Number A B C D E F End Force (lbs) Wt.
