The FireFox® 2 F L is a pneumatic-hydraulic blind rivet nut setting tool with just setting force adjustment for blind rivet nuts with left hand thread. As a variant of the FireFox® 2 F, the FireFox® 2 F L is designed for installing blind rivet nuts with left hand thread. Controlling the tool by setting force protects the material to be joined and the thread and anchors the blind rivet nuts securely and with a high level of process reliability. The FireFox® 2 F L is controlled solely by the setting force adjustment. With a pre-set setting force, this can be adjusted quickly and precisely by means of colour coding. The thread of the blind rivet nut is therefore optimally protected while ensuring the blind rivet nut is securely anchored in the material. The ergonomic design makes it easy to use the setting tool whilst avoiding fatigue. Its stability is ensured with a stable rubber foot. The blind rivet setting tool is equipped with an improved riveting mechanism.
