PATTA Pan Head Self Tapping Screw:6g - 3.5 x 19 - DIN 7981

This fastener is a combi pan head self tapping screw manufactured to the DIN 7981 standard. It features a nominal diameter of 3.5mm and a nominal length of 19mm with a 6g screw gauge. These screws are designed for applications where a self drilling or self tapping function is required, eliminating the need for pre-drilling in many materials. Buyers select this type for its efficient installation process and reliable holding power in sheet metal and light structural components. When choosing a size, consider the thickness of the material being joined and the required clamping force to ensure the 3.5mm diameter provides adequate shear strength. The 19mm length should be sufficient to penetrate the substrate while leaving appropriate thread engagement for the base material.
