Broad Head Bull Pin

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.

    Klein also has a full line of spud wrenches, if you want to tighten that bolt once it’s in the hole. Handy, when your up in the iron.

    Yeah I ranted a few posts ago about Klein’s site.

    Why is it called a spud wrench? I ran into spud wrenches a while ago and again while I was writing this post and could not find the answer.

    ==============================================
    Spudde is old english [middle actually]for dagger, since the wrench looks like a dagger…

    or possibly from Dannish spyd which is a short or poor knife or Old Norse spjot which is a spear.

    Here in Australia, they call it a scaff (scaffolding) podger. I just bought a ratcheting scaff podger today, by a funny coincidence. 21X24mm is a common size here, has both right on it, and a curved pin on the ither side.

    These can really come in handy when assembling large crates. We had some roughly 14’square crates that we needed to continually set up and break down for a traveling show and without these it’d have taken forever to line up the bolt pattern.

    Klein is THE name for quality spuds, bull pins and bolt bags.

    I use these everyday, and have a nice assortment of them… 3/4″ and 7/8″, some with cut off, rounded, blunt tips, others with factory tips. The average person has no use for bull pins unless they are building something requiring bolts 1/2″ or larger. For those that do have them, there is a way to get them out of a hole without needing a wrench like the atricle mentioned. You just beat the side of the bull pin with your hammer… don’t worry you wont hurt it. A few good wakes and it should loosen. It helps also if you bolt the item and tighten it before loosening the bull pin.
