• HEX HEAD ROOFING SCREW: Galvanized screws with selfdrilling tip for tin corrugated sheeting metal panels systems. Screws with rubber washer made of carbon steel and has the highest quality weather resistance and selfdrilling tip.
• EPDM WASHER: EPDM (ethylene propylene diene monomer) washer ensures protection against moisture and its passage to the self-drilling or construction (cannot be over-tightened or under-tightened). Reduces thermal motion effects.
• COROSION RESISTANT: Suitable for outdoor use zinc plated steel 12um supports LST EN ISO 12944-2:2000 high corrosion protection standard. RAL Powder coated Hex Head 60-80um collor matcing and resistan to damage during instalation.
• INSTALATION: SW 8 hex nut driver needed, no predrill neded, self-drilling, fast instalation, self-tapping tip drills through the steel les than in 2s.
• COMPATIBILITY: Commonly used for thin roof and segments instalation to the wood frame (both hardwood and softwood). Screws with EPDM (ethylene propylene diene monomer) washer has the highest quality weather resistance fits for wide variety roofing sheets.

HEX HEAD SELF-DRILLING ROOFING SCREW Roofing screws are simply a type of fastener. They work by fixing sheeting to metal or wood structures, and are tailored specifically to roof maintenance. Although purposefully designed for outdoor work, they are capable for use in a number of internal projects. The most common metal roofing screws are hex head. Material - hardeneg steel are the most common. Coating - Galvanized screws are the most common. The screw head is usually. SPECIFICATIONS: HEXAGON HEAD The hexagonal head fits perfectly to the torque bit and transmits the torque optimally. EPDM WASHER The EPDM washer ensures protection against moisture and its passage to the self-drilling or construction (cannot be over-tightened or under-tightened). SPECIAL TEMPERING Thanks to the special hardening technology, these self-drilling tools are strong, but also resistant to the effects of the atmosphere. DRILL It does not require pre-drilling in the tin (up to 2.5 mm thick), so the work becomes even faster. ANTI-CORROSION PROTECTION 12 µm anti-corrosion zinc layer reliably protects against corrosion.
