Got a European car or some tricky fasteners? This Vector Tools 11-piece XZN spline socket bit set is here to save the day. XZN bits (also called triple square or 12-point spline) are super common on VW, Audi, BMW, and other imports—so if you’ve ever struggled with those weird bolts, this kit’s for you. The bits are made from tough chrome vanadium steel and have a 10mm hex shank that locks securely into your driver. You get two lengths for each size: 1-1/4 inch (30mm) and 3 inch (75mm) bits in M5, M6, M8, M10, and M12. Plus, there’s a handy 1/2-inch drive to 10mm hex adapter included so you can use these with your ratchet or impact wrench. Everything comes neatly packed in a snap-shut plastic case to keep things organized. Perfect for brake jobs, transmission work, suspension repairs, or any DIY project where those 12-point spline fasteners show up. No more rounding off bolts—grab the right bit and get back to work.
