What do the numbers on bolts signify?
 

I just bought some aluminum bolts in an Excalibur box, they are Easton XX75 2216's. What do all these numbers mean?

The first number is the width of the shaft and the second number it the wall thickness. Check out Easton's website.

THE FIRST NUMBER IS IN 64'S of an inchTHE DIAMETER IS 22/64
THE SECOND NUMBER IS IN THOUSANDS AND IS WALL THICKNESS SO THE WALL OF THAT SHAFT IS 16 THOUSANDS THICK.
Also we call them arrows not bolts I believe that historicly a bolt was the steel cross bow shaft that was steel with a pile head and use to penatrate a knights armor. Lee

Thanks, I checked Eastons site prior to making this post, but didn't see what I was looking for.
There must be an easier way to buy these things.. I don't like the right hand spin, and I don't like the 5" vanes.
I am still working on my terminology, I have seen them called bolts, as well as arrows.. I would have called them the long skinny things with all the numbers on it if I hadn't seen the word "bolt" used so often..:)That is probably why I didn't see the info on Eastons site, it's hard to look something up when you don't know just what it is your looking for.
On a better note, the fly fast and straight, nice arrows.

One word of caution that you must use if your are trying to find your own custom bolt/arrow. You need to find out what the minimum total arrow weight must be for your CB before you go to light. If you go to light, you may gain arrow speed but you can have a dry fire affect on your CB. You will not notice it at first, but after enough shoots, you get a big whack in the face and now you have a busted limb bow! I know Horton's minimum totalweight is 431, I think Tenpoints is 415, and on Barnett's web site they do not say the word minimum but they recommend 475 for the quad 400 and similar bows, 454 for the quad 300 and similar, and all the smaller slower bows the recommend 372, but they do not say if that is the minimum or not. Be careful and do not ruin a good bow and then turn around and say it is junk because of what you did. I also forgot about Excal's, but I do not know what there minimum is. Good luck!

I just put new vanes on the arrows, went from a 5" to a 4", these are made for this bow so I think they should be within Excalibur's specs.
Also, when I put on the new vanes I realized the nocks were plastic, so I had to put in aluminum just to get my Fletcher's adapter into them, so up went my weight again.. I think I am safe.
So far I have been pretty careful with the weights I am using, in most instances I have gone heavier than recommended, today I am trying to get close to the factory specs for my Exocet and gain some speed.
Good point about being too light, I will factor that in.. Thanks.

minimum arrow weights for excal's are 325 gr for the vixen amd 350 gr for all other models.[8D]

I need a scale..Nobody seems to have them in stock.
I may take a trip to the local head shop and pick up a scale that weighs in grams, then use Google to convert it, I just tried it (Google) and it works fine.
My old palm pilot has a great program for conversions, but oddly it doesn't do grains.
I really want to get out and shoot these new arrows.

Arlene at the Bow Shop sold me an electonic scale but I don't remember the price.

If you are referring to bow shops then they never do, at least I have never seen one. But if you go to a place that sells reloading stuff they all sell scales and will have one in stock most of the time. Or you can try Midwayusa.com and they have a bunch of them.
