Function: Type-approved countersunk screw, No. SC0621-09, with specially designed thread that is screwed directly into the lightweight concrete and lightweight tiles without pre-drilling.
Track type bit: TX 30 and 40.
Material: Case hardened steel.
Coating: Zincotech Au, corrosivity class C4, for outdoor use.
Installation instructions: Screw in the screw without pre-drilling the lightweight concrete/lightweight tiles, screw with a low torque to avoid over-tightening the screw.
