Reliable thin sheet metal joints

EJOT SHEETtracs® supports the goal of designers to continuously reduce the weight and cost of finished manufactured products through the use of thinner sheet materials. Until its development, designers faced the challenge of achieving a secure joint whilst ensuring that the thickness of the components to be connected at least matched the pitch of the sheet metal screws. This issue meant that many types of fasteners used in thin sheet joining quickly reached their limits as sheet thicknesses reduced. The EJOT SHEETtracs® self-tapping screw overcomes this challenge. It features an innovative thread design to make the jointing of pre-punched sheets between 0.5mm and 1.5mm thick a reality. This makes it suitable for a wide range of applications and a few typical examples include white goods, automotive, aerospace, lightweight construction and assembly.

Innovative thread design

EJOT SHEETtracs® eliminates the need to use a metric 60° thread screw, which can represent a weak point in the joint as a result of the female thread it forms. Instead, the self-tapping screw features a 45° (30° / 15°) asymmetric flank angle designed to displace material to create a stronger female thread in the sheet. The stripping torque level of the joint is increased, and multiple repeat assemblies are possible. In the lower, tapered area of the screw, the flank angle is reversed, and the resulting through draught is formed mainly into fastening direction. The non-circular thread forming zone ensures easy, centred application and the raised thread areas ensure a secure penetration of the sheet material. The circular cross section in the upper, load bearing thread results in higher thread engagement in the sheet metal compared to non-circular thread geometries.

SHEETtracs® Application Check

The EJOT SHEETtracs® is a self-tapping screw for reliable thin sheet metal joints with pilot hole. Check that it is right for your application with our online tool – the SHEETtracs® Application Check. This enables the relevant values for the fastening application to be determined by entering the materials and sheet thicknesses which are to be joined. These values are, amongst others, the required pre-hole diameter and a recommended tightening torque considering different screw surfaces.
