1. What is the size of extended wheel bolts?
These items are made of exactly wheel bolts specifications:
Thread Size: M14x1.5
Ball seat/conical seat is available for aftermarket wheels;
It is recommended that choose a set of aftermarket wheel bolts that is the same thread as the original equipped one. At the BONOSS store, we have lined up these ISO Grade 12.9 wheel bolts according to the specifications of the OE ones. Just tell us the model and year of your car, simple and high effective.
2. What are BONOSS extended wheel bolts on cars?
BONOSS extended wheel bolts apply forged SCM440 alloy steel material. The forged process provides great fatigue strength and tensile strength, hard and high-temperature resistance. They have been fully TÜV ISO standard certificated: Tensile Strength ≥ 1,282Mpa, Limited Life Range Test ≥ 2,000,000 Stress Cycles Without Damage, Ultimate Tensile Load ≥ 152,000N, Proof Load ≥ 121,000N, and Hardness (Vickers) ≥ 394. In addition, the precision of BONOSS extended lug bolts has reached 0.02mm. High-precision car wheel bolts provide high surface integrity, stability, and reliability, and ensure a smooth installation experience.
3. What seat types of extended wheel bolts do I need?
BONOSS extended wheel bolts are designed with floating seats. The floating seats are replaceable which allows for a perfect fit on any wheel. They are mainly available in two options depending on lug bolt size: conical seat and ball seat (R13 or R14). Besides, the separate design eliminates the bolts loosening and abnormal sound caused by the PCD hole coaxially deviation between the vehicle hub and wheels while driving. Since the floating seats are not fixed, they can effectively prevent your beautiful wheels from being scratched by the bolts. If you plan to keep the stock wheels, you need wheel bolts with the same seat type as the stock ones. If you intend to run aftermarket wheels, then both radius and conical seats are possible.
4. Will the extended wheel bolts come loose?
If a wheel bolt breaks due to corrosion, it may gradually loosen. BONOSS extended wheel bolts apply an excellent Electrophoretic coating process. It is useful to protect your wheel bolts from corrosion. Every part of the surface is evenly coated with the paint, nowhere is missing. This improves the appearance of wheel bolts. Moreover, it also behaves greatly to stand up to extreme environments such as water, sunlight, chemicals, etc. This means Electrophoretic-coating extended wheel bolts are not easy to corrode or oxidate which makes them safely work for long-term use.
5. How long are extended wheel bolts for wheel spacers?
When it comes to extended wheel bolts for wheel spacers, the thread engagement length is critical. There is a golden rule: at the minimum, thread engagement length must be equal to or greater than the diameter of the fastener. If you install 10mm spacers, simply add up 10mm to the stock bolt length, the result value is the length of the extended bolts. (OEM bolt length + spacer thickness = extended wheel bolt length). BONOSS offers a full line of extended wheel bolts to suit your new wheels or wheel spacers, lengths from 27mm to 75mm.
6. What does the “BONOSS Engraved” mean?
In order to get maximum performance and better experience, it is vital that you have brand new wheel bolts for whatever purpose you want to achieve. Before leaving the factory, the tech staff will do a series of inspections to make sure that they meet the design specification. To keep the fake products away, each BONOSS extended wheel bolt is “BONOSS engraved”, meaning these extended wheel bolts are made by BONOSS’s own factory, the quality is guaranteed, customers’ interests are protected, and BONOSS takes the quality responsibility.
