What types of fasteners does YH Fastener manufacture?

We manufacture machine screws, self tapping screws, sealing screws, shoulder screws, sems screws, captive screws, security screws, nylon patch screws, carbide insert screws and set screws, plus hex keys, Torx keys and spring and ball plungers, in both standard and custom versions.

Can you produce non-standard screws from my drawings?

Yes. Our engineering team reviews 2D drawings, 3D models or physical samples, confirms material, head style, drive, thread and finish, and then builds tooling for cold heading and thread rolling. Non-standard and international-standard parts are both supported.

Which quality certifications does your factory hold?

Our production system operates under ISO 9001, ISO 14001 and IATF 16949. Every batch passes multi-stage inspection from incoming wire rod to final packing, and inspection records can be provided with shipments.

How do you prevent screws from loosening under vibration?

Depending on the application we recommend pre-applied nylon patches, sems screws with captive washers, or shoulder and sealing designs. The right solution is selected based on joint material, required re-use cycles, torque and operating temperature.

Do you export to my country and how do I start a project?

YH Fastener ships to more than 60 countries. Request our catalog or contact our sales engineers with your drawing, quantity and target application, and we will reply with a technical review within 24 hours.

Frequently Asked Questions (FAQ)

Q: What materials are available for your self tapping screws?

We offer high-hardness carbon steel, SUS304 stainless steel, and SUS316 stainless steel with multiple coating choices like zinc plating, black oxide, nickel plating, and passivation to meet distinct anti-corrosion environments.

Q: Can these self tapping screws be driven without pre-drilled holes?

Our screws feature sharp, precision-rolled tapping threads capable of directly cutting into plastics, soft woods, and thin sheet metals. For harder or thicker metal substrates, pilot holes are recommended to ensure optimal thread engagement.

Q: Do you offer OEM and custom fastener manufacturing?

Yes, we support full OEM/ODM services including non-standard head styles, specialized PT/tri-lobular thread profiles, custom dimensions (M2–M8), and personalized laser marking according to your technical drawings.

Q: What is your typical lead time and minimum order quantity (MOQ)?

Small trial orders and standard in-stock sizes are supported with flexible low MOQs. Mass production orders generally deliver within 5 to 15 working days depending on quantity and surface finish requirements.

Q: How is product quality controlled throughout production?

Our manufacturing facility operates under ISO9001 certified protocols. Every production batch undergoes comprehensive testing, including hardness analysis, thread tapping verification, salt spray anti-rust tests, and tensile inspections.

Q: Can I request free samples for fit and tensile testing?

Yes, we gladly supply free samples of standard sizes for performance testing. Please send us your size requirements and project details to arrange fast dispatch.
