QUICK FLOW® 自攻螺絲

QUICK FLOW® is Böllhoff’s universal, economical fastener for thin sheet materials.

Lightweight construction methods are advancing all the time. The economic advantages are obvious, but technical implementation often presents a major challenge. To enable the fastening of thin sheet materials and thin-walled components without the need for internally threaded elements, we have developed QUICK FLOW® self-tapping fasteners.

Principle

The hard-wearing spiral tip means you can fasten the screw without having to predrill a hole. Material combinations such as aluminium and steel are also possible. The geometry of the screw point forms a rim hole in the thin-walled sheet, making it suitable for a wide range of applications. The reusable metric internal thread is formed in the same process. The result is an adequate coverage of the metric thread flanks. Automated assembly is also possible. High overtorque values ensure the necessary process reliability.
