Rollcage Bolts?

[cskip]

Earlier today I tried to fit a "roadsport" cage to my S3.  I thought I was prepared by purchasing in advance a new set of bolts - here. - for fitting from beneath.  So you can imagine my surprise when they don't fit!  The bolts are far too small.

After trying out a few bolts, I found that an M12 bolt is the correct thread.

Is this normal?  

Where can I purchase shallow/low head bolts that are M12?  Are they available on CC Parts site - I can't find them?

Is the cage metric or imperial? (when was it built?)

It is an Imperial cage.  Made by Safety Devices.  I am not sure of the age.

I doubt it matters, but it is a tall cage.

Hi Skip,

My tall imperial roadsport cage uses 1/2" bolts . The bad news is that CC are showing as out of stock so I guess it's normal headed bolts and angle-grinder time.

That's what I did too

Thanks for the link Chris, that certainly would do the trick.  I might try giving Redline a call the morning.

I have an odd one with a groove cut to clear threads. It has a 3mm thickness head if you get the grinder out. Also grind a socket to remove the chamfer and get a better grip. Finally copious amounts of copper slip when you put the bolt in.

i have a 1/2 inch unf tap if you're nearby and need to clean the threads out.

I was going to suggest that it wasn't M12....

I don't do those up massively tight. They cannot come out because of the damper. And at least it means you will be able to undo them.

I'm sure Redline will have some with the heads turned down.

Update:  Redline haven't got the required bolts.  So looks like fun time with an angle grinder!
