Beag's 67 Chevelle. Supercharged Summer

I think the most common temp sticks I had and used was a 250. I had others up to 600 IIRC but they were rarely used. Most of the higher temp sticks were used to ensure inter-pass temps weren't exceeded on some of the aluminum jobs we did. Very easy to take the temper out of aluminum when the weld is a large multi-pass.

the 250 stick was the "go to" pre-heat stick as so much of the stuff we were doing called for a 250F pre-heat.

I have forgotten so much in the last ten years. Now I'm just a mouth breathing garbage truck driver. :pimp:

In a TC it's not possible to go through several cycles.
You see the splined end.View attachment 341900

The splined end breaks off once the bolt is tensioned correctly .

Hence the name tension control. It allows any monkey to get the correct tension on a bolt.
It's a life saver for me..as I can trust the bolt. And not the person installing bolts.
Unfortunately these days I build more bridges then buildings. (Hey I didn't realize that myself until this moment)
And those aren't allowed in bridges yet.
Anyway, they are a single use bolt.
Once you break of the splined end.... And if you have to remove it for a reason..... It's a new bolt going back in the hole.

When I was a millwright we did that with all stainless bolts. Once it came out it was pitched. Didn't matter if we stuck em in last week.
 
In the Navy we weren't allowed to use adjustable wrenches, except for an occasional ford wrench. A pipe wrench was a HUGE no-go. That's not to say they weren't in the plant tool box, but you'd better not let one of the chiefs see you using it.

They brain washed me good enough that I rarely reach for an adjustable wrench even today. Plus being in the old vehicle hobby and coming across previous owner abuses of those types of wrenches has also made me reluctant to use them.

They have specialized tension control guns, you pop them on and both elements spin.

So pretty much it holds the spline until the nut is torqued enough it twists the spline off. You can't use them outside because then that twisted off part will rust or what's the reason?

They make TC bolts in galvanized.
You typically don't use them in bridge construction because the DOTs haven't accepted use of them, they still want to use a hex head bolt so they can control Turn of nut tightening procedures, Structurally they're just as strong as any other bolt, no reason why you couldn't use them due that. Mostly the reason they're one time use bolts is because once you shear off the splines, now you have nothing to hold the bolt with, so there's no way to prevent it from turning in the back side.

Dumb question...how often does the back side spin while trying to remove the bolts? Seems like that could be a headache sometimes.

Lots of times, it's a huge headache. Iron workers have their tricks. Sometimes a big vise grip works, or they weld a tang on to the head of bolt to hold it with a vise grips or pliers. or take the nut from another bolt welded onto the head so they can actually put a wrench on the bolt head to hold it.
the bolts are junk at that point in time so it doesn't really matter if you weld to them or do anything else.

Yeah I guess I was saying the part that gets twisted off is no longer protected from rust regardless of what coating they have on the outside before you twist it off. I also don't see any reason why they could make that bolt have hex on the back. But I suppose then someone could reuse them which is what they are trying to avoid.

Interesting fasteners, thanks for the sideline/job info....

When they use them outside, after they break off the splines the iron workers will use a cold galv product to go back and spray them.

another application that these are super handy in is where you can't get to the back side.
lot of structural bolts you can't actually get to the back side to get a wrench on. Job site conditions, the outside facade on a high-rise building, where is just not conducive to get to the back side. Etc,
 
As far as making a TC with a hex on the back side, I've often thought that myself. I would have to agree with you the only thing I can think of is to prevent reuse.

Of course I've caught some shady Ironworkers reusing TCs anyway....
 
I'm glad that you enjoyed it. I actually enjoy talking about it. Like I mentioned, I don't know everything, never did, never will, don't even want to for that matter.
I hope everybody that's been following all this stuff learned something to!

Fuel relay harness didn't show up today. UPS pushed it until tomorrow. :angry1:

Spider gears are supposed to be here Sunday.
Two day shipping for free. That's a win. :waytogo:
Maybe be can get a one wheel burnout emoji? :burnout:

If you are doing donuts they should both spin just fine.
 
I thought you had a few too lol. Not to mention a sacrilegious 6.0.

Just swap the engine out of the stepside and replace it with the 6.0 and a few Chinese whistles.

That'll free a good one up for this car....

I think you have an L29 in your stable too iirc :thinking:


All kinds of options better than my old clapped out peanut port jobby lol

My white stepside has a junk 350 in it..

It runs but I've owned it for 5 years and have yet to change the oil and filter in it.
