Klein Tools 3256 Broad-Head Bull Pin Made of Forged, Made in USA, Heat-Treaded Steel With Black Finish, 1-1/16-Inch

I'm an iron worker and these are the only bull pins I use. The material they are made out of is like no other. The durability and performance are what you expect of Klein

I'm building a quonset hut by hand along side 80 and 86 year old family members. Without these bull-pins, we would never be able to align the 9ft long pieces of corrugated galvalume and install the 2550 bolts required to finish the project. After literally thousands of uses, I can see no wear on these tools. Two of these, along with a Klein Tools 5416TFR bolt bag, have been strapped to my hip for days on end. If you require a 1-tool option for bolts, a spud wrench would be helpful, but in my particular circumstance, I have no use for a wrench while on the scaffold lifting and placing these parts. After a loose fitting of the bolts, we allow the pieces to settle together and then torque them in. If you're working alone to align pieces like this, insert the bull pin and use a piece of string or bank line to tie it off in the direction that you need leverage. During the stints of solo work on this project while my coworkers were infirmed or in the hospital, I used this trick many times.For the price, these were the cheapest and most useful tools required for my workshop build. If you're trying to align bolt holes in metal structures, do yourself a favor and buy two of these. Leverage with one and sink the second as far as possible to keep the alignment while you bolt the first. When lining up bolt holes in all three dimensions, a minimum of two is required.

This bad boy right here is your best friend. If you know, you know 👌 all in one alignment tool, poker, hammer-like device, and apprentice adjuster. A must have in any tool kit!

I work in the oil field and have to line flanges up all the time! Works good!

I don't use it much, but it's good to have (at work). The first one slipped out of the package in shipping, had to reorder. No difficulty there.

Use it for lining up holes on mining equipment and it not only lines them up, but rounds out the jagged holes. It also rounds out my welding nozzle. I'll use this thing for years to come. Quality tool here.

Lucky 2nd one arrived. These are designed to poke thru. First one never arrivedNice hole in box were it poked itself out.2nd one almost didn't make itHalve out of package on my steps.Item itself is great .Just needs to be packaged better to survive trip.

It's a Klein tool. I will die, before it fails

As an Ironworker/Carpenter. I have the pleasure of doing everything from the concrete to standing the structural steel and either bolting/connecting or welding. Klein has always been my go to company for Erection tools. As we live in Canada, it is hard to get other makes/models of said spuds/bull pins etc.. Klein hasn’t let me down and I will continue to use their tools.

Like a carrot but far superior

Well. I am not using this tool for it's intended purpose. So my review is a little bit off. I purchased it to be used as a drift for making holes in hot steel. I was worried it would not hold up, but was happily surprised when I drifted the perfect hole. The head did not deform, and believe me when I say I was beaimting on it with a 2 and a half pound hammer. Well made good steel. I will be looking at different sizes if the company makes them. Fellow blacksmiths. If you are in a budget like myself this is the drift for you

Nice quality , bought it for work but will probably never get to use it. Injury preventing me from working. Worth the money

Not even 24hrs after ordering did I receive it ready to go perfect
