## Description

Product Description The Klein Tools Broad-Head Bull Pin is machined from quality alloy steel and resists corrosion and mushrooming. Its angled head and smooth blending of radii increase strength and reduce the danger of chipping. For more than 160 years, Klein Tools has manufactured premium-quality, professional-grade hand tools that deliver the performance, durability and precision needed to get the job done right. Our family of engineers, workers and craftsman continue to put six generations of expertise into every tool we create by using only the highest quality materials, superior workmanship, and keeping manufacturing as close to home as we can. Klein isn't just the name of our company, it's also our family name. And since we're an American company that's family-owned and family-run, you know you can count on us to be here tomorrow. Klein Tools doesn't just make great products, we make great products that stand up to the demands of the professionals who use them every day ... Since 1857. From the Manufacturer Since 1857, the company operated by Mathias Klein and his descendants to the fifth generation, has grown and developed along with the telecommunications and electrical industries where Klein pliers first found major usages. Today, Klein Tools, Inc. represents much more than Klein pliers. The company's product line has broadened to include virtually every major type of hand tool used in construction, electronics, mining, and general industry in addition to the electrical and telecommunications fields. Klein offers a lifetime warranty on material defects and workmanship for the normal life of the product. The Klein 3256 10-inch Standard Bull Pin is a great addition to your tool collection. This pin is ideal for aligning bolt holes when working with steel construction. Below the head, the squared-off shoulders have been forged to provide a surface for applying wrench to loosen wedged bull pins. The broad head adds resistance to "mushrooming" permitting much longer use than is possible with conventional designs. The angle of the head and smooth blending of radii increase strength and reduce the danger of chipping, and reduces chance of pin slipping. The long, even taper reduces binding and hang-up. Machined from quality alloy steel, the 3256 has a 1-1/16-inch top diameter by 1/4-inch point diameter, and a rust and corrosion resistant black finish. The Klein 3256 10-inch Broad Head Bull Pin is sold one item per package.

Review: 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.

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.

Great bull pin

### ⭐⭐⭐⭐⭐ I've used these every day for a month
*by T***L on February 2, 2024*

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.
