This special self-tapping screw for light metal applications is designed for direct assembly into cast holes. It allows you to realize significant cost savings compared to metric screws, as the number of work steps can be reduced. With its high clamp load and vibration resistance, the ALtracs® Plus offers long-term stability, even under high dynamic and thermal stress.

Benefits of ALtracs® Plus Screws

Benefits

Up to 40%

cost savings thanks to fewer work steps

Benefits

The EJOT ALtracs® Plus saves time and money since it allows you to eliminate work steps such as thread cutting.

Benefits

Optimized

thread design with 33° flank angle

Benefits

The 33° flank angle creates stronger female threads compared to 60°. The larger thread root reinforces the female thread in the weaker metals, while the asymmetric flank optimizes material displacement, creating a large thread engagement area.

Benefits

Lightweight

construction

Benefits

The optimized thread geometry of the ALtracs® Plus facilitates the use of smaller and shorter screws, which saves weight – while still offering consistently high strength values.

Benefits

Safe Assembly

thanks to low installation and failure torque

Benefits

The low installation and high failure torques of ALtracs® Plus screws facilitate a broad range for secure installation with standard pneumatic and electric drivers.
