SMJ machine cut brass serrated wheel nut

SMJ have released these high-precision serrated flange wheel nuts which are machined from brass material.  Weighing in at approx. 1.4 grams each, using the brass nuts as a replacement for the standard aluminium wheel nuts on 1/10 scale touring cars can help achieve higher traction.  The machined serrations bite firmly into the wheel to securely hold it in place.
