The tools are made from heat-treated chrome‑molybdenum (CR‑MO) steel with a black oxide finish to resist wear and protect wheel finish during use. Note: this set is not suitable for 10‑spline, large truck lug nuts, external hex spike designs, or deep\/oversized units.\u003c\/p\u003e\n\n\u003ch3\u003eHow do I know if this set will fit my lug nuts?\u003c\/h3\u003e\n\n\u003cp\u003eStart by identifying three things: the lug nut style (spline, star, hex or fluted hex), the number of splines if applicable, and the outer diameter of the lug. The set includes both inner spline sockets and outer diameter adapters to match many common passenger car and light truck patterns.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eCompatible sizes include M10x1.25, M12x1.25, M12x1.5, 1\/2-20, M14x1.5, M14x2, 9\/16-18.\u003c\/li\u003e\n  \u003cli\u003eContains 8 inner spline diameters and 8 outer adapter sizes to mix and match fits.\u003c\/li\u003e\n  \u003cli\u003eNot compatible with 10‑spline, large\/oversized, external hex spike, or deep recessed lug nuts.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat tools are included and how are they used?\u003c\/h3\u003e\n\n\u003cp\u003eThe kit supplies a variety of inner and outer sockets so you can find an interference fit on most locking nuts by trial fitting.
