The Chevy S-10, now no longer in production, features a wheel bolt pattern of 5 X4.75" and this means it useS5 lug nuts to secure its wheels to their hubs that form a diameter of 4.75 inches. This pattern can also be described aS5 X120mm. "MM" stands for millimeters and it's useful to know most wheel bolts or nuts are measured and ordered using the metric system. The "hex" of a lug nut refers to the diameter of the top of the lug nut. While this measurement can be significant when switching out rims, the diameter of the shaft is more relevant to fit. Thread size refers to the size of the shaft and the space in between the its grooves or "threads". The Chevy S-10 features a hex of 19 mm and a thread size of M12-1.50.
Why would my 1986 Chevy S10 Blazer Tahoe 2.8 4x4 have a 4.5 lug pattern not the 4.75???????? Really..........
