Help finding a bolt

Have you checked to see if a Socket Head Cap screw has full thread ? Have used them before in similar applications and 7/16 has a 39 Rockwell and a Tensil strenght of 18,000lbs

 

Jeez I'm embar***ed. I just put chrome lugs on my Chevy which is why I had 7/16's on the brain. Don you're right, I just checked and theyre 1/2" x 20. Should be easier to find

 

And here they are.

I'm a dumb***.

1/2 by 20 are easy to find. Just call your favorite catalog speed shop.

By the way it has nothing to do with the thread but for any of you fellas using a chebby engine 7/16 is the proper stock size for you motor mounts.

 

Haha, I wish I had a nickle for every time I've done something like that. I used to be able to look at a bolt head or thread size and know what wrench I needed. Now I try every one in the tool box before I get the right one.

No, just aging like the rest of us. As you age and collect so much info, the brain's filing system gets taxed at times. You won't be to the dumb*** stage until you actually spend the $40 for the incorrect part only to discover upon installation that it's incorrect!

 

Uh...... Is this up for debate?

 

and for the record B7 threaded rod is grade 8 mcmastercarr sells it in 3 foot lengths
1/2-20- 3' sells for $9.12 each

At least you figured it out before buying the 3 something each ones.

Now you owe every one of us who spent the last few hours hunting the 7/16-20x2 gr 8 fully threaded cap screws a brew and probably owe Don more than that

 

Haha done.

 

I have the same set up as you, what Don says.
