Screw (set) SMM10x20 /100pcs/ 650743

SMM10x20 screw is a fastening element designed to connect components in various systems – from building structures to installations. Made of steel, it is available in several finishing options, allowing it to be adapted to specific environmental conditions and project requirements.

Application and safety

The SMM10x20 screw meets the requirements of the E90 functional maintenance system, in accordance with DIN 4102-12 standard. This means that it provides at least 90 minutes of functional maintenance of critical devices in the building during a fire. It is particularly important in installations:

• fire alarm systems,
• fire alarm systems,
• emergency lighting,
• sprinkler systems.

Materials and workmanship

Available material variants allow for optimal selection of the screw for the specifics of the application:

• G – Galvanized steel: Standard solution providing basic corrosion protection.
• F – Hot-dip galvanized steel (PN-EN ISO 1461:2023-02): Provides higher corrosion resistance than galvanized steel. Ideal for outdoor or aggressive environments.
• FP – Zinc flake coating (PN-EN ISO 10683:2018-11): Highest level of corrosion protection, particularly recommended for use in harsh atmospheric and chemical conditions.
• E – Stainless steel: Provides excellent corrosion resistance and high temperature resistance. Ideal for use in chemically aggressive environments or exposed to moisture.

The screw is made of steel grade 5.8 according to DIN 933 standard, which guarantees its strength and reliability. The screw size is M10 x 20 mm.
