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 hole and tap threads in a single operation. Self-tapping screws tap their own threads but generally require a pre-drilled hole.
What materials are available for your self-drilling screws?
We offer self-drilling screws in Carbon Steel (C1022A) and Stainless Steel grades, including SS304, SS410, and SS201, to suit different load and environmental requirements.
Can I get customized sizes and surface finishes?
Yes, we support custom specifications for sizes (diameter M3.5–M6.3, length 13mm–150mm), head configurations, and finishes like Zinc Plated, Ruspert Coated, Black Oxide, and Epoxy Coating.
What are the main applications for Tek screws?
They are widely used for fastening metal sheets, roofing and cladding installations, fixing steel profiles, HVAC ductwork, electrical enclosures, and automotive assemblies.
What is your typical lead time and shipping port?
