M4 六角螺帽 | 鋼製三價鋅 (1500 / 包)

Used a full bag of these on a custom jig project and every single nut threaded onto the bolts perfectly with no binding. The hex heads are crisp and the zinc finish looks clean and consistent across the whole package. At this quantity, it’s a solid value for anyone doing high-volume M4 fastening.

The trivalent zinc coating on these M4 nuts gives a consistent, corrosion-resistant finish that I appreciate for outdoor projects. After using about a hundred of them, every single one threaded smoothly onto my stainless steel bolts without any binding. Definitely a solid value for the quantity you

The threads cut cleanly on my bolts, and all 1500 nuts in the package were consistently sized with no burrs. Feels like a solid, professional-grade batch for production work.
