Self-tapping screw gyprock-metal 3.5x32 countersunk partial thread oxide (pack of 30) euro hanger STROYMETIZ 2020051

Metal self-tapping screws are metal rods with fine threads and a head in the form of a countersunk or flat head. The thread, extending to the head of the fastener, ensures a tight connection of identical and different types of materials. Pointed fasteners are used to attach thin metal sheets to metal, plastic, and wood bases, as well as when assembling wooden products, for example, for attaching drywall. Screws with a drill bit at the end are used when working with aluminum, steel, and iron parts with a thickness from 0.9 mm. Metal self-tapping screws are made of carbon and alloy steel. The surface of the products is additionally coated with a zinc or phosphate coating, which protects the fasteners from corrosion. Our screws are characterized by: strength - withstand significant breaking loads; reliability - create strong clamping force and hold the connection well; ease of use - enter the metal neatly, without leaving burrs or chips. When purchasing metal self-tapping screws and bolts, the following main characteristics should be taken into account: length – must completely cover the total thickness of the joined structure with a small margin; diameter – the larger it is, the higher the strength characteristics of the fastener.
