Need quality rack bolts

Today I noticed my rack had pivoted. I remember having trouble getting the bolts tight because they seemed to have shallow allen holes and stripped easily. I tried tightening again today and, yep, they strip easily alright. So now I need a quality rack bolt that won't strip! Any suggestions?

I was just thinking about picking up some M5 x 1mm bolts at Home Depot...stainless, preferably. Whaddayathink?

ACE hardware mainly due to the fact that it is a half mile away.

I don't even know where an ACE is...I'm less concerned about where to get it, more concerned on WHAT to get.

Right now I'm hunting for a Grade 8 M5x.8x18mm Socket Head. Anyone else have suggestions on good bolts?

I think it's 10-32 that's an almost identical size to the metric. You might want to try NAPA or a dedicated fastener shop if you can't find it in Big Box Depot.

whatever bolts you end up using, put some blue Loctite on the threads.

And yeah, nothing less than stainless steel will do. Nothing plated, nothing painted.

What about Ti? I found a good deal on some Ti ones online and was thinking those might be less likely to strip at the head!

I can't believe how shallow the allen hole is on the bolts that came with the rack...they're virtually worthless.

10-32, eh?

Thanks

SAE Grade 8 bolts will corrode. Stainless is soft. Ti will gall. So it's a tradeoff.

+1 for the threadlocker, though.

Personally, I use stainless. I live close to Tacoma Screw (no, it's not a brothel), and they carry pretty much every kind of bolt I can think of.

What does "gall" mean? As for Grade 8 bolts corroding, is there a way to prevent it?

My problem is I can't get my rack tight when the socket strips, and my rack pivots...me no likey. I just want something hard, or with a deep socket.

Thanks all

heh, I worked in an industrial supply warehouse many years ago...anything is available...for a price.

My ideal rack bolt would be something like this:
10-32x1" Button Head Cap Screw, square drive, silicon bronze with a nylon plug.

What is the nylon plug? And, if they're so good, can one actually obtain such sweet bolts? If so where?

I found these at ACE hoser. Black. 4mm Allen head. Check different ACE's. Not all the same. Nice hefty bolts.

grade

Grade 5 will work too. A little less likely to shear. Most interference thread nuts work, but I agree that blue locktite is best. 32 threads per inch or 24 threads per inch? Either one will get the job done if locktite is used. Get what is easiest to find. A hex head, a socket head, even a slotted or phillips head will work. Hex socket heads will let you use the wrenches on your multi-tool, but if you install them at home, with the locktite, or other thread locker, you can use shop tools and whatever head was easiest to find.

Standard hardware store stainless (typically 304) is fine, blue locktite, which also comes in solid "chapstick" like tube dispensers now. Try Eagle or McGuckens. Grade 8 is a bit of overkill

Read all about Galling

A little thread locker helps this but on your application galling isn't really an issue.

Stainless steel is soft? I never heard this. I thought stainless steel was hard.

I've not dealt with bolts but in the metal shop I worked at, it was much harder cutting a sheet of stainless steel than regular steel.
