Features and benefits

  • Stainless steel self drilling screw made ​​with BIMETAL
  • Hardened surface of the thread (flexible core). Corrosion resistant zinc coating of thickness not less than 12 um. The shape of the thread and its height is closely related to the intended use of self drilling fixing into steel construction.
  • Self vulcanizing EPDM washer. Temperature and UV resistant. The special shape of the washer ensures proper seating of the sealing material on the outer cladding material fixture which guarantees a proper seal.
  • The drill bit is designed to provide quick and trouble-free installation in the steel. Sharp point of the drill prevents movement of the surface of the fixture.
