Bolt with "10" on the head

[ovrszd]

One of the more useful things I have is a complete metric tap and die set. Then, given any nut or bolt, I can determine the thread pitch, diameter, etc right on the spot. Then I can walk into a store knowing the bolt I want and not have to spend time jerking around and trying to measure threads and pitch.

Yep, I've used that method. Especially if I'm sending my wife on the parts run.

If I go I just take the bolt. Screw nuts on it until I get a fit.

Or get one of these to hang next to your bolt trays:

Nut & Bolt Thread Checker (Inch & Metric) - Tap And Die Sets - Amazon.com

Great idea.

My O'Reilly's parts store has one hanging by the counter.

Great, another item added to my Amazon Wish List (to buy list) because of this site.

It's like a bad dream, it just goes on and on and on......

That was my plan.
It holds the "down angled part" that the front wheel attaches to, to the main axle.

That is a metric marking for metric common high strength metric bolts which are similar to SAE grade 8 only a bit stronger than grade 8 hardware. You can get them most any place that carries metric hardware like TSC for example. Just match the length, thread pitch and strength. Good luck getting out the broken ones because those suckers are hard.

Actually found 4 broken bolts. 3 of them came out easily (maybe part of the problem?) The other 1 is being a big pain. It is the one in the "reamer bolt" hole. Had to get a tougher drill bit, will try again this weekend.

CAT bolts are the king of bolts. If I'm ever in need of a bolt with unquestionable character, I get a CAT bolt.

EDIT--let me add that I buy most bolts at JD like ovrsd does. They seem to be much better quality than comparable farm store bolts for not much more money.

Cat bolts (grade 8) aren't really the 'King' of bolts but for most all industrial/commercial applications they are. For comparison, Grade 5 is a 120ksi ultimate tensile strength and a Grade 8 is 150ksi. Now the King of bolts are found in the aerospace industry. Not really uncommon to find 220ksi bolts! That said, these high strength bolts are very expensive and are relatively brittle compared to lower grades and as such are not used much if at all outside the aerospace industry. Sorry if I went off on a tangent here but just wanted to spread some uncommon knowledge.

Wow. 4 broken? Were they all in the same area/same side?
Yep those hardened bolts are murder on drills. Just keep to low speed if you can. Have you been in touch with the dealer about it? Definitely get a paper trail behind you, if you haven't.
