Frequently Asked Questions
Can you offer neutral (unbranded) packaging for sales on Southeast Asian e-commerce platforms such as Shopee and Lazada?
Yes, we offer neutral packaging without any branding for customers selling on e-commerce platforms like Shopee and Lazada. Custom packaging and labeling can also be arranged based on your specific requirements.
What self tapping screws sizes do you have available for different materials?
We offer a wide range of self tapping screws sizes suitable for metal, wood, and plastic applications to fit various project needs.
What is the difference between self tapping screws and self drilling screws?
Self tapping screws create their own threads in a pre-drilled hole, while self drilling screws (also called TEK screws) feature a drill-like point that eliminates the need for pre-drilling. Our zinc plated Phillips head self tapping screws are sharp-pointed and ideal for applications where a pre-drilled hole exists or softer base materials are used.
Do you manufacture self tapping screws with Phillips drive only?
Our primary production includes Phillips pan head self tapping screws, but we also offer hex head, flat head, and wafer head options upon request. All screw types are available with zinc plated, black oxide, or stainless steel finishes depending on your application needs.
Can I import self tapping screws from your factory to the Middle East or Africa?
Absolutely. We are an experienced China-based manufacturer exporting zinc plated self tappers to Saudi Arabia, UAE, Egypt, Nigeria, Kenya, and many other countries. We offer competitive prices, flexible trade terms (FOB/CIF/DDP), and support bulk orders with fast delivery.
