Tapered / Concaved Lug Nut Washers M10 / M12

The Details
Most aftermarket wheels look great—but many aren’t machined with a tapered seat. At the same time, most lug nuts do have a taper. That mismatch creates uneven contact, so the lug nuts don’t sit flush and the wheel isn’t fully secured.

• Provides even clamping force for safer wheel mounting
• Helps protect your wheel finish—no more damaged powder coating
• Compatible with both M10 and M12 studs (fits most Ruckus and GY6 hubs)
• Easy installation—simply place the washer between the wheel and lug nut

Why Choose These?
They fix a common issue riders often don’t notice until it’s too late—loose wheels or damaged finishes. It’s a small upgrade that makes a big impact on safety and long-term durability.

*Douglas DWT Wheels have M1o holes from factory. Our GY6 Hubs are M10 bolt pattern and we use our M10 to M12 adapter bolts (these have M10 bolt and M12 Head) to use Standard Lug Nut M12x1.5 thread of your choice.  If you have someones elses Gy6 Hub with M12 holes you will have to drill out the bolt holes on the wheel.
