R-HLX-HF-ZF Self-tapping, concrete screw with hexagonal head in a flake zinc coating.

R-HLX screws are coated with ZF flake zinc coating, which guarantees increased corrosion resistance.  
High parameters in cracked and uncracked concrete C20/25 – C50/60.  
Three anchoring depths  
Polish production  
Thanks to the use of thread to the end of the anchor length, we ensure better cooperation with the substrate, thereby achieving higher load capacities.  
Additional ribbing of the washer ensures better pressing of the fastened element to the surface of the substrate.  
Reliable and simple installation.  
Coated with flake zinc coating - corrosion class C1-C4.  
Induction hardening ensures high surface hardness and high core impact strength  
The new thread shape ensures quick and easy installation  
The optimized tip shape ensures efficient anchoring from the beginning of the thread.
