Head

F type - Flush
Standard design enabling the head to be flush-finished into the workpiece. This type of head is completely buried in metal sheet thicknesses ≥ 1 mm.

R type - Reduced flush
Head with minimized dimensions, allowing crimping that is 25% to 50% closer to the edges and folds, in comparison with flush type F studs, whilst conserving the same flush finish characteristics. This design limits movement of the workpiece material during crimping.

T type - Extra thin metal sheet
This shape allows crimping on very thin metal sheets from 0.5 mm, thanks to the groove which is located closer to the bosses. A flush finish is impossible on these extra-fine metal sheet thicknesses.

H type - High resistance
Because the head is generously-sized, the H type enables very high tensile force and torque resistance.
This type of stud is intended for applications which are subject to very high stress, for metal sheet thicknesses ≥ 1.2 mm.

L type - Wide high resistance
This wide non-flush head improves resistance on thin metal sheet ≥ 1 mm. Its wide head surface transmits the force of the application, whilst minimizing pressure stress on the metal sheet.

I type - Concealed
This type of stud is suitable where aesthetic and/or seal criteria are of overriding importance. This component is crimped into a closed end hole, rendering the fixation points invisible.
