Wafer head screws are distinguished by their low-profile, flat heads, which provide a sleek finish and minimize protrusion above the surface. The designation 1% 201% 4% refers to specific mechanical and material properties that make these screws particularly effective in certain applications. The combination of these percentages generally relates to the composition of the screw materials and their tensile strength.

1. Material Compatibility Ensure that the self-drilling bolts used are compatible with the materials being fastened. Different materials may require specific bolt types or sizes to optimize performance.

Stainless steel hex head self-tapping screws are a versatile and durable fastening solution that is commonly used in a variety of applications. These screws are specifically designed to create their own threads as they are driven into the material, making them incredibly easy to install without the need for pre-drilling.
