(Also known as 12 point and spline bits)
This kit is specifically designed for your European automobile. We include all 9 known sizes of triple square bit (M4, M5, M6, M8, M10, M12, M14, M16 and M18) PLUS an extra long M10 for inner CV bolt access. To keep them affordable, we use 3 sizes of friction bases. The money saved on all those chrome bases allows us to use the highest grades of steel for the bits. The M4, 5, 6 & 8 are S2 tool steel. The M10, 12 & 14 are SAE8660 tool steel. The M16 and 18 are SAE6150 tool steel. This set is NOT recommended for head bolt removal due to length and clearance issues. This set is NOT impact tool rated. Head bolt bits and impact-rated bits are sold separately below.
