Motorcycle Fasteners Are More Than Just a Thread Size
A motorcycle bolt should not be selected simply because it screws into the same thread.
Depending on the application, the correct replacement may also depend on:
- Thread diameter and pitch.
- Bolt length and threaded length.
- Head type and dimensions.
- Shoulder dimensions.
- Washers, collars or spacers.
- Material.
- Strength or property class.
- Intended mounting position.
That is why much of our range is organised around specific motorcycle makes, models, year ranges and fitting locations rather than simply selling bags of generic bolts.
How We Develop Biker Bling Products
Our product-development work can include researching OEM parts information, comparing original part numbers, checking model-year differences, measuring genuine fasteners and carrying out practical fitting checks where appropriate.
We have also built our own fastener information and cross-reference data over many years of working with motorcycle parts.
When information cannot be established confidently, our approach is to investigate it rather than guess.
For a detailed look at this process, read Inside Biker Bling: Our Workshop, Bikes & How We Work.
Model-Specific Motorcycle Bolt Kits
Motorcycles frequently use more than one type of fastener, even where the nominal thread diameter appears to be the same.
Depending on the kit, this can include differences in bolt length, head dimensions, shoulders, washers, collars, well nuts, clips and other associated hardware.
Our model-specific products are therefore developed around the intended motorcycle and fitting location.
Always check the individual product listing for the exact model and year coverage, fixing locations and hardware supplied.
Why We Use 304 Stainless Steel
Many Biker Bling replacement fasteners are manufactured from 304-family stainless steel, commonly associated with the A2 stainless fastener designation.
304 stainless steel provides useful corrosion resistance and appearance for many suitable motorcycle applications.
However, stainless steel is not automatically suitable for every motorcycle fastener.
Some locations require a particular high-strength or special-purpose fastener specified by the motorcycle manufacturer. Where this applies, the manufacturer’s requirements should take priority.
You can learn more in our Motorcycle Bolt Materials Explained and Motorcycle Bolt Strength Grades Explained guides.
Built Around Real Motorcycle Work
Our understanding of motorcycle fasteners has developed through years of researching parts, measuring components, preparing kits and working with motorcycles in practical workshop situations.
That practical experience influences how we organise our products.
Where a kit covers several areas of a motorcycle, the fasteners can be separated and identified by their intended fitting location to make installation easier.
We also continue to review existing product information as better information, new measurements or model-year differences become available.
