Self Piercing Screws
Self Piercing Screws
EJOT Fastening Systems offers Self Piercing Screws. These are ideally suitable for high-strength sheet metal joints. The flow drilling EJOT FDS screw opens up new possibilities for high strength screw joints, due to the increased thread engagement in the formed through draught. The female metric thread, formed without chips during the insertion process, is true to gauge and therefore a standard metric screw can be used for repairs. These are suitable for sheet metal thickness: steel (0.3 to 2.0 mm); aluminium (0.3 to 3.5 mm); magnesium (1.0 to 3.5 mm). Features: no problems regarding hole overlapping of clearance and pilot hole; no material waste while forming the through draught/no chips during thread forming; several metric threads are engaged; safety margin concerning a large distance between installation and stripping torque; high shearing strength and pull-out force; assembly in different sheet surfaces is possible; high break loose torque and vibration resistance; repeat assemblies also possible by using standard metric screws; earthing assemblies; easy to disassemble and recyclable; and low overall joint costs.
