Description
This is a pack of 4mm serrated wheel lock nuts for cars and trucks with 4mm axles. Pro-line wants your wheels to stay where they belong - on your car! pro-line's new 4mm wheel nuts feature dual protection against the dreaded "wheel loss" found at RC tracks around the world. 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 pro-line's new serrated nuts is the nylon lock ring that prevents the nuts from loosening due to vibration and centrifugal effects.
