Frequently Asked Questions
What is the difference between self-drilling and self-tapping screws?
+
Self-drilling screws have a tip shaped like a drill bit, allowing them to drill their own pilot holes in one operation. Self-tapping screws require a pre-drilled pilot hole before they can cut threads into the material.
Can these self-drilling screws drill through thick metal plates?
+
Yes. Depending on the drill point size (from #2 to #5), our self-drilling screws can drill through metal sheets ranging from light gauge up to 12.5mm thick steel plates.
What materials are available for your screws?
+
We offer screws manufactured from Carbon Steel (C1022A) for high tensile strength, and Stainless Steel (SS304, SS410, SS201) for superior rust and corrosion resistance.
Do you provide customized packaging and labeling options?
+
Yes. We support custom packaging options including bulk cartons, custom color boxes, plastic containers, and private labeling according to your brand requirements.
What is your typical delivery lead time?
+
Our lead time generally ranges from 7 to 25 days, depending on the specifications of the order, quantities, and current production schedules.
