Zinc coated hex washer nuts for tough hardware mounting jobs
✔️ #6-32 threads 5/16 hex 7/16 outer diameter pack of 100 units

Zinc plated hex washer lock nuts bring a flat load spreading base and toothed inner core to stop bolts from backing out under stress. These handy fasteners are pretty sweet for slapping together car trim, shop cabinets, gear mounts, and wood frames that need steady grip without constant wrench time. You get a full box of one hundred ready to drop right in.

✅ Fine #6-32 threading meshes securely onto standard machine bolts
✅ Welded flange spreads stress away from delicate mounting surfaces
✅ Spring steel teeth grip firmly to block rotational movement
✅ Protective zinc finish resists surface rust during outdoor exposure

💡 Why do mechanics prefer toothed washer nuts over smooth flange fasteners during engine repairs?

- The serrated inner ring bites into both the bolt shank and host material to prevent unwanted spin
- Flanged bases increase surface contact area to distribute clamping force evenly across fragile substrates
- Fine pitch grooves multiply thread engagement points that naturally fight back against impact shifting
