The self-drilling screw for corrosion-resistant installation in steel and aluminium.
Field of Application:
For St 12, St 13, St 14, St 33, St 37, UST 37, RSt 37, St 44, St 50, St 52, other unalloyed steels up to a tensile strength of 510 N/mm2, plus aluminium and other soft metals. For mounting aluminium and steel trapezoidal plates onto thick aluminium and steel substructures. In addition, for all cases where thick materials (≥ 4.0-12 mm) need to be drilled and, at the same time, a certain level of corrosion resistance is required.
Advantages:
- Drilling, thread forming and bolting in one go.
- Considerably reduced time and effort.
- Rustproof mounting with the A2 stainless steel thread.
- Special Ruspert coating (zinc-aluminium lamellar coating) lubricates the stainless steel thread and protects the steel tip against corrosion.
Advice:
Minimum screw length = clamping force + material thickness + drill bit tip length + 3 mm. RECA sebSta must always be screwed in until only the threads of the stainless steel section are engaged.
