About This Product
These external tooth washers are a solid choice when you need extra grip on your fasteners.

You get 30 pieces, all M6 size with an 11mm outer diameter, made from carbon steel and zinc plated so they resist corrosion and wear.

The serrated teeth dig into both the bolt head and the surface underneath, creating spring tension that adds friction and stops things from loosening up from vibration.

They distribute the load evenly too, so your connection stays tight and stable.
Installation is a snap—just press or twist them onto the shaft and you're done.
Perfect for mechanical, electronic, construction, automotive, and industrial applications.

The silver finish looks clean and professional.

If you're tired of bolts backing out, these little washers are a cheap fix that really works.
