Magna-Grip ® The Original Wide Grip Range Fastener Proven in Thousands of Applications. Vibration resistant Flush-breaking Easy installation 3/16"-3/8" 1 Huck Magna-Grip ® Magna-Grip® fasteners. A unique, lock-groove design ensures a secure installation. Huck brand Magna-Grip fasteners offer a generous selection of diameters — from 3/16 to 3/8 inch — for light to heavy-duty applications. They break flush, every time, and provide multi-thickness capability thanks to a wide grip range for each diameter. With Magna-Grip fasteners you achieve clean installations across-theboard, for a variety of assembly thicknesses, while stocking less inventory. In addition to consistent clamp force, shear, and tensile strength, the Huck Magna-Grip ensures absolute vibration resistance with a unique locking-groove design. It simply can’t come loose no matter how demanding the application — which reduces rework and warranty claims, providing long-term savings for your company and increased satisfaction for your customers. With Magna-Grip fasteners, quality installations do not depend upon the skill of the worker or a correctly calibrated tool. They install in seconds (up to 1,200 per hour) and require no more than a glance to confirm a correct installation: If the core pin is flush with the collar, the Magna-Grip fastener has been properly installed. It’s that simple. And the installation process can be mastered in minutes with minimal training. 2 Installation Sequence Perfect installations do not depend upon worker skill or a precisely calibrated impact wrench — and can be achieved with just a few minutes training. 1 2 The fastener pin is inserted through a prepared hole. The precision collar is placed over the other end. The Huck installation tool is applied and engages the pin. When the tool is activated, it pulls the pin in a straight line while pushing down on the collar. 3 The tool moves forward over the collar, molding the collar material into the grooves of the pin. This process, called “swaging,” causes a precise stretching of the pin and collar, developing the fastener’s clamping force. 4 When swaging is complete the pintail is automatically tensioned off, flush with the end of the collar. The tool then pushes off from the collar. The result is a permanent, mechanically locked fastener. Secure, fast installation. ■ ■ ■ F lush-breaking, lock-groove design provides a wide grip range to reduce inventory requirements.
