Nylok Patch Screws Pre Applied Nylon Patch Anti Vibration Fasteners

If you need fasteners that stay tight under constant shaking and movement, our Nylok patch screws are a practical choice. The pink nylon patch is pre bonded on the thread section, which creates friction during assembly and stops unintended loosening from vibration.

We do the patch coating work in our own workshop. Every batch follows fixed standards for patch position, thickness and adhesion. We do not use generic coating. We can adjust the patch range strictly according to your drawing requirements, whether you only need partial thread coating or full thread coverage.

We supply these locking fasteners in many common head forms. You can pick socket cap head, truss pan head, torx head and shoulder style as shown in our sample set. Material choices include carbon steel and stainless steel. Surface finishes cover black oxide, zinc plating and passivation for different corrosion resistance needs.

Size range covers standard metric sizes, and we also accept non standard custom dimensions. For projects with special torque requirements, we can run pre production sample testing before mass order.

YH Fastener focuses on custom fastener manufacturing for overseas industrial buyers. We handle drawing review, prototype making, coating processing and final packing all in house. We have worked with clients from automation, medical equipment, new energy and automotive assembly fields for years.

Send over your drawing or sample specs if you have a locking fastener demand. Our engineering team will review your requirement and share quotation and sample lead time within one working day. Small trial orders are welcome.
