Will these fit my aftermarket wheels?

M12x1.5 is the standard thread pitch for most vehicles. The 50mm extended length clears most popular wheel designs, but verify your wheel center bore and offset—some deep-dish or forged wheels run tight. Test-fit one nut before committing to all twenty.

Do I need to prep or paint these before installing?

No. The black aluminum finish ships ready to install. The knurled surface won't scratch wheel faces if you're careful during installation.

What torque spec should I use?

Refer to your vehicle's service manual for the correct torque value—it varies by application. Aluminum lug nuts handle standard torque specs without issue, but never exceed your manufacturer's recommended range.
