Description

Stainless steel screws made from martensitic steel of grade C1 are characterized by very high strength and are capable of transmitting high mechanical loads and torque compared to stainless steel grades A2 or A4. They are an ideal solution for less stable wood species without acidic substances and for installations where high strength and reliable fastening are required.
The screw shank features a double thread with a relieving pitch. The head is equipped with a Torx 20 or Torx 25 drive, depending on the screw diameter, providing very firm and stable bit engagement.

For wood species with a high content of acidic substances or for environments with a risk of exposure to extremely corrosive conditions, consider using screws made of A2 stainless steel. In coastal areas or environments with high exposure to salts or chlorides, consider fasteners made of grade A4 stainless steel, which offer higher corrosion resistance but lower mechanical strength.

Areas of Application

Installation of wooden decks, carpenters, joiners, roofers, manufacturers of prefabricated components for timber constructions, façade cladding, balconies, fences, playground equipment, etc.
Especially suitable for screwing into hardwood.

Installation Information

Screws with a drill point are not intended for use with wall plugs
Pre-drilling of holes, including countersinking for the screw heads, is recommended
For contact with acidic substances, chlorides, or saline environments, consider using stainless steel screws of grade A2 or A4
