Choosing the right self-tapping screw for light-gauge steel (0.6 – 1.5 mm) comes down to three questions: are you fastening into a pre-punched or pre-drilled hole, or not? Is the substrate uniform or multi-layer? And what holding force do you actually need?guide to bolt strength grade markings for the 8.8 / 10.9 / 12.9 system. Every pattern we ship is validated under the tensile and torque testing covered in our ISO 9001 / 14001 / 45001 recertification.
Self-Tapping Screws in Light-Gauge Steel: Choosing the Right Tip Geometry
Self-drilling vs. self-tapping, thread-forming vs. thread-cutting, and the tip-geometry trade-offs when fastening into 0.6–1.5 mm cold-formed steel.
