SUR Marketing offers a comprehensive range of hex washer head, self-tapping screws specifically designed for sheet metal to sheet metal fastening applications. These screws are engineered with features that effectively address the challenges associated with metal to metal fastening.
One notable advantage of our screws is their exceptional strength and holding capabilities, achieved through a meticulous heat treatment process. This treatment significantly enhances their performance, ensuring secure and long-lasting fastening solutions.
To cater to diverse requirements, SUR Marketing provides self-tapping screws in a variety of materials, including stainless steel, carbon steel, and alloy steel. This material selection not only enables the screws to withstand extensive wear and tear but also enhances their resistance to corrosion. As a result, our screws maintain their integrity even when exposed to harsh environmental conditions.
An inherent benefit of our self-tapping screws is their ability to create threads as they are driven into the material, eliminating the need for pre-drilling pilot holes. This feature saves valuable time and effort during the fastening process, making it more efficient and streamlined.
