The REFERENCE torque spec for lug nuts on a 2003-2025 Mazda Mazda3 BK/BL/BM/BN/BP will be 108 – 147 NM. Please note that different wheel nuts need different torque values. It is highly recommended to consult a tire expert before operating. Typically, a wheel with five lug nuts is tightened in a star-shaped pattern. This ensures an even weight distribution across the wheel mounting plate. As long as you torque them properly, high-quality aftermarket Mazda3 lug nuts are exactly safe to use.
Generally, there are three types of Mazda 3 lug nuts: steel nuts, aluminum nuts, and titanium nuts. Aluminum nuts and steel nuts are the most common and cost-effective types. Almost all OEM Mazda 3 lug nuts are made of steel alloy. In comparing the strength of steel and aluminum, technically steel is harder and stronger. Besides, its strength means that it is unlikely to bend or stretch. When crossing bumpy roads, steel Mazda3 lug nuts can offer more resistance to impact cracks.
What Size Socket is A Mazda 3 Lug Nut?
The socket size of a Mazda 3 lug nut is 21mm (13/16″). If you plan to replace the stock lug nuts, grabbing the correct socket is important. As long as the seat type and size fit, you can use OEM lug nuts on aftermarket wheels. But once there are differences, new wheel nuts are required. This is because various manufacturing companies make aftermarket wheels, which are probably different from the OEM ones, like the lug seat types and the diameter of the lug holes.
What Lug Pattern is Mazda 3?
The lug pattern of a Mazda 3 is 5×114.3mm so you need 20 pcs lug nuts to fasten the wheels. It’s NOT safe to drive a car with a missing lug nut. Because even if it is a lug nut missing, there will be uneven pressure on the wheel hub, meaning the other lug nuts are more likely to loosen. As the Mazda3 lug nuts loosen enough, the wheels can fall off suddenly, which is one of the most frightening things that can happen to you. If you find missing wheel nuts, it’s a good idea to get a set of quality wheel nuts that can greatly resist corrosion or other damage.
Where is the Mazda 3 Lug Nut Key?
If your Mazda 3 comes with antitheft wheel lug nuts, then you must use a special key to remove the locking lug nut. This key is usually stored in the glove compartment, center console storage, storage box, or trunk. If you purchase aftermarket lug nuts, make sure that you have the hardware to be able to install/remove those wheel locks.
Particularly, BONOSS provides 4 pcs of Heptagon wheel locks in a forged 50BV30 steel lug nut kit. Different from the traditional hexagonal lug nuts, the heptagon types are hard to remove if you don’t have the proper removal key. Due to the irregular shape, it is difficult for thieves to remove your finest wheels. The surfaces are exquisite Mirror-black which maximally beautifies your wheel while protecting the lug nuts from rusting.
