What Makes a Self-Tapping Screw Actually Suitable for Metal Applications?
Self-tapping screws carry a lot of weight in metal assembly, quite literally. Plenty of buyers assume a point is all that matters, then end up with stripped holes, cracked panels, or joints that fail under load. Picking the right fastener takes more than a glance at the packaging. Thread pitch, point style, material hardness, and coating quality all factor in. Contractors and manufacturers who understand these details tend to waste less material and build connections that actually hold.
