Klein Tools 3255 Bull Pin, Made in USA, Broad Head Bull Pin Resists Corrosion and Mushrooming, Heat Treated Steel with Black Finish, 1-1/4-Inch

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'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

Great product. Thank you

a nice tool!

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.

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.

Great pricing and fast shipping
