 |
|
Can't seem to find the "official name" of the bolts that have a groove machined in them at the end of the bolt - commonly found on the areas of the karts (tie rods, pedals, steering columns) that need safety wire per org regulations. These grooves allow the use of the following safety clip (I know where to get these) as shown below:
Anyone a.) know the name and b.) where (bolt house) can I order these types of bolts?
Thanks. |

Don't know the "official" name of them, they aren't referenced in any of Carroll Smith's books 
But you will probably have to get them from kart suppliers rather than industrial fastener suppliers since I think they come from Italy.
From what I remember Kart Parts Unlimited had both the bolts and safety clips in stock last time I bought fasteners from them. Check with your local kart shop 
Cheers,

Agree with you there. Carroll is the final "say" on these things. Appreciate the reply. |

I think technology is running ahead of nameology. I don't think you'll find them from industrial suppliers. I believe they are made on a limited production basis by kart manufactures.
Some of your finer kart shops have drilled bolts for use with cotter pins if you don't like drilling the bolts yourself.

heh! That would be a learning experience... I've done a few, when no way to get one in a hurry, but I don't recommend it as a career path. Works much better if you can grind the groove with a tool post grinder.

I believe that the proper term is "@#$%^ing bolt that the clip fell off of", or at least that's what I've heard in safety tech.

I guess that's because they don't require safety wire in Italy?
You probably don't need it when you change chassis every other race
Seriously folks, drilling for safety wire is only hard the first 10 times. After that you just get it done and move on. It's not worth the extra money as far as I'm concerned and proper safety wire is 1000 times better than those little clips IMHO....
Learn how to select and use fasteners properly, the life you save might be your own
Cheers,

A couple of issues come to mind....
Usually if they are not the "USA Type", they're don't have enough thread past the nut to be able to properly drill. So you end up buying a crap load of hardware to replace the stock stuff.
Some organization don't recognize the "USA Type" fastener clips, they have to be safety wired or cotter pinned....

Your local tech committee can tell you what's required at your track. From memory all brake hardware, steering hardware and weights should be safety wired. If you're not buying the fancy "USA" type or pre-drilled you're probably looking at ~$25 max to replace all of it plus $10 for drill bits.
Every form of motor racing requires safety wiring AFAIK so learning how to do it right makes sense no matter what.
