ecosyn○ MRX the ideal screw for fastening chrome steel

The screws are manufactured from a martensitic, hardened and tempered chrome steel with higher resistance to corrosion (comparable with A2 grade stainless steel). Besides aluminium also sheet steel and rust-resistant thin sheet metal can be drilled through.





 ecosyn○ stamped drill points  Self-cutting screws
 Stamped drill points: safe and secure
 drilling without the need for prior
 center punching.
 Self-cutting screws: fasten efficiently 
 without the need of a pilot hole.
