LANDMASTER
LANDMASTER 64 Titanium One-Piece Rear Wheel Bolt M12 x L60 x P1.5 for BMW Motorrad
Integrating the genuine "wheel bolt + tapered ring" into a single structure.
Some BMW Motorrad models use a combination of two parts to secure the rear wheel:
Genuine wheel bolt
BMW Part Number: 36312333226
and a
Tapered ring
BMW Part Number: 36132302339
Instead of simply replacing this genuine two-piece structure with titanium, LANDMASTER integrates the wheel bolt and tapered section.
We designed and manufactured this as a dedicated Ti-6Al-4V rear wheel bolt specifically for BMW Motorrad.
This is not just a "titanium replacement bolt."
Based on BMW's genuine wheel fastening structure, this is an original LANDMASTER dedicated product, manufactured with the tapered section that contacts the wheel integrated into the bolt body.
Adopting Ti-6Al-4V, also known as 64-titanium
The material used is Ti-6Al-4V titanium alloy, also known as 64-titanium.
It is a material that is lightweight, yet possesses high strength and excellent corrosion resistance.
This product is a special large-diameter and long size, M12×L60×P1.5.
Furthermore, instead of a common bolt shape, it has a dedicated shape with the tapered section that contacts the wheel integrated into it.
The head and tapered sections are manufactured by machining from Ti-6Al-4V material.
And the threaded section uses roll-forming.
Head and tapered sections are machined
For genuine BMW parts, the structure is separate:
Wheel bolt
＋
Tapered ring
At LANDMASTER, we integrated the function of this tapered ring into the bolt body, and machined the head to the tapered section as a single, integrated structure.
Therefore, the genuine tapered ring is not used during installation.
This is not a combination of a commercially available titanium bolt and a tapered ring; it is specially designed for the BMW Motorrad rear wheel fastening, including the part that contacts the wheel.
It is a bolt manufactured with consideration not only for the bolt itself, but also for how it receives and secures the wheel.
Threads are roll-formed, a costly process
A major feature of this product is the adoption of roll-forming for the threaded section.
Unlike cut threads, which create screw threads by shaving material, roll-forming is a manufacturing method that forms screw threads by plastically deforming the material using a die.
For small-batch production of titanium bolts, due to issues of cost and manufacturing processes, very few products employ roll-forming for the threaded section.
In particular, the combination of:
Ti-6Al-4V
M12×L60×P1.5
Integrated tapered section
Head and tapered sections are custom-machined
Threads are roll-formed
is a specification completely different from general-purpose titanium bolts.
This is not a product intended for mass production, but rather a bolt produced in small quantities specifically for BMW Motorrad, yet roll-forming is deliberately used for the threaded section despite the higher cost.
The very fact that it was manufactured with such an elaborate process is a significant characteristic of this bolt.
Manufactured using both "machining" and "roll-forming" as appropriate
This product is not made entirely with the same manufacturing method.
The head and tapered sections, which require a dedicated shape, are machined.
The threaded section is roll-formed.
The manufacturing method is chosen according to each part.
While the head, tapered section, shank, and threaded section are all configured as a single Ti-6Al-4V bolt, different manufacturing processes are employed for the part that forms the shape and the part that forms the thread.
This is an original LANDMASTER product that has been custom-made, not only changing the material to titanium, but also in terms of the manufacturing method.
Integrated structure that does not use the genuine tapered ring
For genuine BMW parts, the wheel bolt and tapered ring are combined when securing the rear wheel.
At LANDMASTER, we have integrated this tapered section into the bolt body.
Therefore, the structure is:
Head
Tapered section
Shank
Threaded section
This is a Ti-6Al-4V rear wheel bolt with all these parts integrated.
The genuine tapered ring is not used.
A major feature is that this is not a product where "only the genuine bolt has been replaced with titanium," but rather the genuine two-piece structure itself has been re-evaluated and designed as an integrated structure.

The length and number of bolts used may differ depending on the vehicle model, year, and wheel specifications.
Before purchasing, please confirm the part number "36312333226" and the bolt size of the BMW genuine wheel bolt currently installed.
Producing the same specifications in small quantities today is not easy.
This product was produced in small quantities by LANDMASTER as a dedicated product for BMW Motorrad.
Special size M12×L60×P1.5.
Ti-6Al-4V.
Integrated tapered section.
Head and tapered sections are machined.
And the threaded section is roll-formed.
This is not a product that uses general-purpose titanium bolts on the market.
It is specially designed and manufactured from scratch to match the BMW genuine rear wheel fastening structure.
A particularly important point is that, despite being a small-batch production item, roll-forming is even used for the threaded section.
Roll-forming is not a process that can be easily adopted just because it's small-batch production.
Products that prepare processing conditions for a small number of Ti-6Al-4V bolts and invest in the roll-forming process are now extremely rare in their specifications.
Furthermore, in this case, it's not a standard bolt shape, but a special shape with the BMW genuine tapered ring section integrated.
Not only is the material 64-titanium, but it also combines:
Dedicated design
Machining
Integrated tapered structure
Roll-formed threads
If we were to try to produce the same specifications in small quantities again today, not only the material costs, but also machining, roll-forming, setup, and handling of special shapes would require considerable production costs for each process.
A unique piece for BMW, produced during the LANDMASTER era.
It's not just a bolt made of titanium because it's light.
We re-evaluated BMW's genuine "wheel bolt + tapered ring" structure and integrated the tapered section.
The head and tapered section are machined from Ti-6Al-4V, and despite being a small-batch production item, a costly roll-forming process was adopted for the threaded section.
This is an original LANDMASTER 64-titanium rear wheel bolt, specially designed for BMW Motorrad and manufactured with meticulous attention to the manufacturing method.
Old LANDMASTER products that have been stored for a long time are now being re-released for sale.
