A bull pin has nothing to do with baseball — that would be a bull pen — except possibly being involved in the construction of the stadium. But you probably want it on deck when you’re bolting metal structures together. You use a bull pin to align holes, so you can bolt parts together — you just drive the pin’s tapered shaft into the hole.
Since OSHA frowns upon using tools with mushroomed heads, the large head on either of Klein’s broad-head bull pins helps reduce mushrooming when struck, giving the tools a longer usable life. The large head also provides a bigger target to hit with the hammer and helps you keep a grip on the bull pin when you’re wrenching it around. Squared-off shoulders below the head allow you to loosen wedged pins with a wrench, and the long, even taper helps prevent binding.
These forged and heat-treated bull pins feature a black finish that resists corrosion. The 3255’s shaft measures 13″ long, and the 3256’s shaft measures 10″ long. They’ll run you from $12 to $17 apiece.
