High strength sheet metal joints

Especially in the fast automotive industry, where the used components have to withstand high stress, the demands on fastening technology are high. For example in the car body construction the composite design is on the increase where different materials have to be fastened securely and lastingly. In addition to one-sided accessibility, the removability of the fastener is also very important, especially with regard to recyclability. These complex conditions are a case for the use of the EJOT FDS® screw, which fastens thin sheet metals made of steel and aluminium without the need for a pilot hole and in excellent quality. Work steps such as pre-drilling or pre-punching are no longer necessary. Due to the increased thread engagement in the formed draught a high-strength screw joint is created - without the undesired metal chipping. The screw joint is able to transfer high pull-out as well as shearing forces.

Fastening tool selection

A higher screwdriver speed and a defined end load is needed for flow drilling, thread-forming and tightening of the screw require a high torque. The suitable screw drivers have been developed in cooperation by a EJOT®  and different manufacturers. For exact specification of the suitable tools the FDS® product management will gladly assist you, for determination of the selection criteria we can also carry-out assembly tests in the EJOT® APPLITEC laboratory.
