COLORED HEX HEAD SELF-DRILLING ROOF 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 external work, they are capable for use in a number of internal projects. The most common metal roofing screws are hex head, hex washer head, and pancake head. Material - hardeneg steel are the most common. Coating - Galvanized screws are the most common. The screw head is usually painted the same color as the metal panels. The ETA certificate guarantees that the product meets the requirements of European norms and guarantees quality. SPECIFICATIONS: HEXAGON HEAD The hexagonal head fits perfectly to the torque bit and transmits the torque optimally (max. 2000 rpm during installation). 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). RAL POWDER PAINTS ACCORDING TO RAL Powder paints according to the RAL color palette are long-lasting and protect the color from UV exposure and fading. 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. According to the standard LST EN ISO 12944-2:2000. PACKAGE CONTAINS: 50 pcs.
