T55 bed bolt thread size

I've done a lot of searching, but continue to come up empty handed.

I need to know the thread size/pitch for the Torq 55 bolts that hold the bed to the frame. I mounted some brackets and need to buy bolts that are 1/2" longer. My metric tap and die set does go this large.

Thank you for your time!

 

m12x 1.25 x 3-3/4" long is what I found for second gen. I think it'd be safe to assume it's the same for third gen as well.

 

THANK YOU!!!

 

If that is correct, report back here for future searchers.

 

and if not, take the Bolt to ACE and have it measured...

 

I did that. The bolt is larger than anything Ace Hardeware, Tractor Supply, or Lowes have in metric.

I'm ordering bolts from McMaster Carr. I'll report back. Thanks again!

 

If your tap and die set goes that large, shouldnt be an issue to figure out the threads, no..?

 

Just a note that 12mm is the major diameter. Just measure with calipers. 1.25mm pitch is common. You should have a male tap with that pitch to check against.

 

Did you read my original post? No...?

 

I'm confused.

 

You and me both

 

I think it's a classic case of what the kids are calling a "typo".

 

I did. And it says

Did you mean to say "My metric tap and die set does NOT go this large"?

See why we are confused?

 

Classic

 

What a world we live in where we give thickness and pitch in metric and length in standard.

 

My mistake. No, my tap and die set does not go that large. Sorry for the confusion!

 

I like to mix it up.

 

$13 M12x1.25 mm Self-Locking Nylon Insert Hex Lock Nuts, Pack of 6

M12x1.25, overall length 122mm, 114mm to bolt head, thread length 66mm. Washer is 3mm thick.

 

Wow! Now that's some good information. Thank you!

Want to thank everyone for their input. I apologize for the lack clarity in my original post.

 

The bed is off my truck, so it was easy.
