Adjustable Torque Toggle Screws

Jergens Tru-Center™ Adjustable Torque Toggle Screws are perfect for delicate and fine clamping. Once the end holding force is reached, the head breaks free. Larger radius, straight knurled head for easy turning.
 
Our patented Tru-Center™ products are the only pad type on the market to provide true center-line clamping. 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.
