Zinc-Plated Self-Tapping Screw with Drill Bit for Sandwich Panels

The zinc-plated self-tapping screw with drill bit is designed for fastening sandwich panels and other multilayer cladding materials based on profiled sheeting to the metal frame of a structure. The design of the fastener ensures a strong connection between the cladding and the base.

The shank of the screw has thread cut in the lower and upper parts. The lower thread serves as the main fastening, while the upper thread prevents the screw from spinning and protects the surface of the base from deformation. The reinforced drill-point tip eliminates the need for additional pre-drilling of holes.

The hex head provides convenience when working with a wrench or a screwdriver bit. The metal washer with a seal made of weather-resistant rubber ensures sealing of the joint. The material of manufacture is a high-strength steel alloy with increased carbon content. The top coating is applied by electrolytic (galvanic) zinc plating.
