The most common type of lug nut is the tapered seat or conical seat lug nut. This type of lug nut has two tapers available: 60-degrees and 45-degrees taper, which helps keep it tight in the hole. Tapered seat lug nuts are the most common type of lug nut, and they will work with most wheels. The second type of lug nut has a small ball in the middle that helps keep it tight in the hole and is called a rounded or ball seat. Another type of lug nuts is the mag seats, which are offset seats.

Step 2: Check the Thread Size of the Lug Net

To measure the thread size, measure the distance between the thread on the lug bolt.
