Frequently Asked Questions (FAQ)
Self-tapping screws tap their own mating threads into pre-drilled pilot holes or soft materials, whereas self-drilling screws feature a fluted drill-point tip capable of drilling a hole and forming threads in one single operation.
Our self-tapping screws are engineered for use with sheet metal, structural steel frames, plastics, wood, aluminum extrusions, and composite assemblies.
For standard indoor or mild settings, zinc plating provides good resistance. For outdoor, marine, or highly corrosive industrial conditions, we recommend Ruspert coating, Dacromet, or Stainless Steel (SS304/SS316) grades.
Yes, we support complete OEM/ODM customization, including specific lengths, thread profiles, customized head markings, and private labeled box packaging for global distributors.
Our typical lead time is 7 to 25 days depending on the ordered quantity and surface finish requirements. We offer flexible MOQs suitable for both large-scale industrial projects and wholesale distribution.
