self thread bolt

Self-tapping screws, as the name suggests, create their own thread while being inserted into a pre-drilled hole, eliminating the need for a separate tapping process. They are particularly advantageous when working with plastic, a material known for its variability in hardness, thickness, and thermal expansion properties. Stainless steel, with its inherent corrosion resistance and high tensile strength, makes an ideal choice for manufacturing self-tapping screws that can withstand harsh environments and maintain a secure grip on plastic substrates.
