5th generation quality from a family owned, US company.
Quality from a 5-6 generation, family-owned US company. I buy US made when I can and especially when I need tools that work hard and last, like this Klein Bull Pin. These are great for aligning holes and for my metal working they make torch holes round after the cut while the steel is still hot. Many uses for this tool and I don't need it breaking and throwing metal fragments in my eyes.

Solid and durable tool
Very durable bull prick. Have had 1 for 10 years and still solid. Bought another for a spare. Great product

Works well.
This pin is a good weight, and seems to be built well. It fits into smaller I-Beam holes, and the hammer tip has a large strike face. The reason for four stars is because it doesn’t have a hole for a lanyard tether, so I can’t use it on commercial jobs.

For some one that works with light to heavy pipe and lots of machinery, this bull pin is perfect. Extremely heavy duty. It just feels right in your hand. I’ve used this from drilling bolts into concrete to using it as an alignment tool when connecting flanges.

I've used these every day for a month
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.
