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.

addressing common production‑floor pain points. We supply in‑stock and custom‑built SEMS screws for manual and automated production lines across multiple industrial sectors.
Many volume‑manufacturing sites struggle with washer‑related defects. SEMS screws integrate screw and captive washers into one complete unit
reduce assembly actions and lower the risk of omitted washers. We offer standard stock and custom SEMS screws for manual
they are supplied as a single part
semi‑automatic and high‑speed automated assembly lines.
SEMS screws are pre‑assembled combination fasteners with one or more captive washers. Unlike loose screw and washer sets
