This is a pack of four optional Pro-Line 4mm Serrated Wheel Lock Nuts, and are intended for use with vehicles with 4mm axles. These Pro-Line Blue Anodized Aluminum Nuts have deep serrations that dig into the wheel and provide a secure hold against the rigors of racing and bashing. The second layer of protection delivered by these Pro-Line serrated nuts is the nylon lock ring that prevents the nuts from loosening due to vibration and centrifugal effects. 

Features:

  • Blue Anodized Aluminum Stylish and Lightweight
  • Serrations that dig into the wheel for security
  • Nylon lock nut for second layer of wheel nut security

Pro-Line 4mm Serrated Wheel Locknut (Blue) (4)
Great looking finish on these wheel nuts, they're the first thing I notice when I look at my truck. Once you lock them down they stay on there tight. Only problem is that the nylon came out of two of them after a couple runs. Even though those 2 are still usable, I would have hope they would have lasted longer.
