Bolts,bolts, and bolts?

[Goodman433]

So i found some missing bolts on my rims and need to find them online and that brought me here for a few questions.
How can i tell the difference between m3 and m4?
And does m3 and m4 have diffrent dia.?
Then where can i find the diffrent colors or tops like button head and so forth.
I have injora beadlocks

I've been getting screws here: https://www.boltdepot.com/ .
You'll have to figure out what size you need, length, etc. Highly doubt any
on your wheels are m4.

M3 and M4 is the diameter of the screw. An M3 is a 3mm usually with a .5 thread pitch. They’re likely M2 or M2.5 if they’re the beadlock screws. A caliper would be a easy way to tell the diameter. I’m
Around the stuff enough I have an eye for it. I buy most of my stainless screws in bulk instead of buying kits.

Another thing to know is screws are measured length wise differently. I don’t want to make things confusing but button and cap head screws are measured from the bottom of the head to the end of the thread, where a countersunk screws are measured by overall length.

The number in metric bolt sizes refers to their diameter in millimetres. M3 = roughly 3mm. I buy all my hardware from McMaster Carr unless it's something really oddball that they don't have. Most of their hardware they have technical drawings available if you have any question on the dimensions. They do only sell by the box/bag, so you may end up buying 100 of a certain screw to get them.

Great place (and people) for RC hardware.

I would replace the beadlock bolts with scale hex hardware. Injora sells it, so does SSD and VP. Looks much better in my opinion. Just don’t forget to use thread lock or you will be leaving bolts everywhere. ..

Bulk I buy my screws off of AliExpress. Delivered cheap and in decent time compared to most stuff I have ordered of of that site

LockedUpRC also has the scale hardware sweetness!

In multiple finishes, and acorn nuts as well as the more common scale hex hardware.
