SUCOSO M14x1.25 Extended Lug Bolts – 40mm Shank for BMW
If you own a BMW like a 328i, 335i, or M2, these SUCOSO bolts are engineered for your hub. With a precise M14x1.25 thread pitch and a 40mm shank, they’re ideal for use with wheel spacers. The conical seat ensures a snug fit on most aftermarket wheels. CNC high-precision machining gives you clean, flawless threads that screw in smoothly, saving you time during installation.
Durability is a strong point here. Made from SCM 43 steel and passed a 72-hour salt spray test, these bolts resist corrosion and rust far better than standard options. The 17mm hex head works with standard tools, but you should use a hand wrench rather than a power tool to avoid over-torquing. If you need a reliable, long-lasting solution for your BMW’s spacer setup, this set of 20 is a solid choice.
- Precise CNC threads
- Corrosion resistant
- Ideal for BMW spacers
- Hand wrench only

The chrome finish isn’t just for looks. Four-layer plating and a 72-hour salt spray test mean these bolts resist rust and fading, even in harsh conditions. Anti-rust oil adds an extra layer of protection. If you’re tired of dealing with flimsy bolts that fail over time, this set of 20 offers a durable, reliable upgrade that’s easy to install.

Buyer’s Guide: What to Consider
Choosing the right extended wheel bolts involves more than just length. Consider thread pitch, seat type, and material to ensure safety and performance. Here are key factors to guide your decision.
- Thread Pitch: Match the thread pitch (e.g., M12x1.5 or M14x1.25) to your vehicle's hub. Using the wrong pitch can damage threads or cause wheel failure. Always verify your car's specs before purchasing.
- Shank Length: The shank length determines how much thread engages with the hub. For spacers, you need extra length to compensate. Measure your spacer thickness and add the factory thread engagement to find the right shank length.
- Seat Type: Cone seat and ball seat are the two common types. Cone seats are universal for aftermarket wheels, while ball seats match OEM German cars like Audi. Using the wrong seat can cause the bolt to loosen or damage the wheel.
- Material and Coating: High-quality steel like SCM 43 offers strength, while coatings like chrome or black oxide resist corrosion. Look for salt spray test results to ensure durability in harsh conditions.
- Quantity and Fitment: Sets come in 5, 10, or 20 pieces. Ensure you have enough for all wheels. Also, check compatibility with your specific vehicle model and year to avoid fitment issues.
Conclusion
Extended wheel bolts are essential for safe spacer installation. The right set depends on your vehicle’s thread size, seat type, and shank length. For BMW owners, the SUCOSO M14x1.25 set is a top pick, while Audi drivers should opt for the ball seat version. GAsupply offers a durable one-piece design, and Project Innovation provides a long-reach option for Corollas.
Always verify your car’s specifications before buying. Whether you prioritize corrosion resistance, precise fitment, or style, there’s an option here for you. Choose wisely, and enjoy a secure, confident ride.
