Lockbolts, Structural Blind Fasterners and Tooling

Insert the fastener into the hole and slip the installation tool over the pintail. 1 Press the trigger to initiate pulling action. As the tool pulls on the pintail, the solid pin head captures the end of the sleeve and acts to initiate bulb formation and draws the work pieces together. 2 Continued pulling on the pintail expands the bulb to maximum allowable diameter. 3 A spline feature on the pin comes into contact with a step on the sleeve creating an interference lock between the pin and sleeve and the pin breaks. The pin will break close to flush in minimum grip and below flush as the grip increases. 4 1 Tapered hole-seeking tip for quick and easy installation. 2 Unique band annealed bulbing system for superior blind side strength. 3 Positive mechanical pin retention ensures structural integrity. 1 2 3 Secure, Fast Installation 42 Huck ® | Structural Blind Fasteners
