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.

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 seb
Sta must always be screwed in until only the threads of the stainless steel section are engaged.
