Machine Screws
Pan Head | Self Drilling Screws | Selfdrilling Tek Screws
Pan head self-drilling screws from ITA Fasteners are high strength and precision fasteners used for sheet metal applications. Their high hardness and strength combined with their lead threads allow for the perfect fastening of timber-to-metal or metal-to-metal. Since these are self-drilling screws, there is no necessity to drill a pilot hole. However, their accuracy of usage can be improved by using it along with a washer. This also reduces the impact of vibrations or constant movement of the product.
It is available in stainless steel, carbon steel, and alloy steel to bear more wear and tear while also making it more corrosion resistant. It is also resistant to degradation due to acidic and alkaline exposure. The pointed drill bit makes it suitable for high precision applications like machine and electrical components manufacturing. However, it would be better for the structural integrity to use these screws with washers to reduce the impact of metal against wood.
