Twist-Tack™
The Twist-Tack is a self-piercing, one-step metal fastener that attaches thin materials to steel tubing, aluminum extrusions, or lightweight metal castings. Permanent fastening is achieved when the knurled section of the Twist-Tack engages the base metal with a cutting, twisting and wedging action. The Twist-Tack was developed for manufacturers who attach plastic, fabric, rubber and other materials to metal.
