Each nut is heat-treated and cold-forged, finished in a black zinc coating to reduce corrosion, and sized to match common off-road wheels with a 60° tapered seat. The package is intended for aftermarket upgrades or direct replacements on many popular models that require a 17 mm hex engagement and a 35 mm overall length.\u003c\/p\u003e\n\n\u003ch3\u003eWill these lug nuts fit my vehicle?\u003c\/h3\u003e\n\n\u003cp\u003eThey fit wheels that accept M10 x 1.25mm studs and a 60° tapered seat; check your vehicle’s stud pitch and the seat angle before buying.
