Just thought I'd throw this in here to help. If you know the size of the hardware you need here are a couple of useful links:

http://www.mcmaster.com/ this is the on i usually use,

http://www.smallparts.com/

http://www1.mscdirect.com/CGI/NNSRHM,

If you have a SEARS hardware near by they usually have a very good selection up to 5/8 or 3/4 "and 10 to 13 mm.

Fastenal, is spelled with just one 'L'

 

http://www.fastenal.com/web/home.ex

 

Any fasteners that you can find on the web site, can be ordered and shipped to the local store for pickup (for no shipping charge) also, if you do alot of business with them, open an account, the savings are well worth it :D

 

Con......all the fasteners are sold in boxes/bags of 100, Large bolts and some concrete anchors are sold 25-50 per box. If you need only 2 bolts, thats not the place to buy from, but........whens the last time you threw out extra bolts :hmm:

How do you check the sizes of threads on nut and bolts?? a fastener board, tap 'n' dies, or what????

 

Seriously,, I was thinking of putting a board together with different stud and nuts on it labeled with the sizes,, so is there a easier way to find sizes other then looking in a FSM????

Taps and dies, calipers and thread gauges to give an educated guess on which to try to clean threads with.

 

Yeah I need to pick up a thread gauge... Completely forgot about using one of those.. You just don't see them alot is why I guess..

So Jim, are you tabulating these somewhere? :D

 

Pete, If someone posts a random one I have been re-typing in a post I have here and figured you could clean up the thread later, but cherokee's post can stand on its own.

Really? I mean really? Really?

I have never been to Lowe's for anything but plants and a vacuum cleaner. :???:

 

My local ACE hardware has just about every bolt, screw, body panel fasteners or o-rings you could ever need. Once in awhile they don't have a specific item but very few and far between. I've replaced just about every removed bolt with SS bolts (except Jeep specific suspension,engine/drive line bolts), all found at ACE. They even have a big thread finder board ...male & female so there is no guessing.

 

Seems to me Lowe's or even Home Depot are lousy places to get bolts...since they're all in plactic bags.

 

If I can't find it at ACE, I go to NAPA or Fastenal etc. Not a place that sells carpet and washing machines.
