Suitable for lightweight construction with the optimised thread geometry facilitating the use of smaller and shorter screws, while retaining consistently high strength values
High clamp loads and long term stability, even under high dynamic and thermal stress
Up to 40% cost savings through omission of work steps for screw and component
Easy design engineering with the EJOT® ALtra CALC® prognosis programme
High vibration resistance without additional safety elements
High assembly safety due to low installation and failure torque
Where a repair is needed, a metric screw can be used in its place
Lower installation and higher stripping torques enable safer assembly with common pneumatic and electric screwdrivers
FDS®
Flow drill screws for high-strength sheet metal
Flow-drill screw for high-strength joints in sheet metals
One-sided accessibility
Removable and high quality screw joint, with no pre-drilling or punching
No tolerance problems with clearance or threaded holes
No material waste and no swarf
Suitable for use with various sheet surfaces
High loosening torque and vibration resistance, no need for additional safety elements
Easy removal and recycling
Repeat assemblies possible with metric screws
Spiralform®
The self-tapping fastener for steel.
Special thread-forming fastener for reliable and trouble-free metal screw joints according to DIN 7500
Low thread forming torques due to special thread geometry with self-tapping point
The formed thread corresponds to the metric ISO thread DIN 13
High strength values and maximum thread engagement due to circular thread cross section
SHEETtracs®
Reliable assembly of pre-punched thin sheets
High strength of the screw joint due to the formed draught
High vibration resistance
Simple and safe assembly due to good alignment and low installation torque
High stripping torque due to a robust female thread
Circular thread cross section for maximised thread engagement
