Klein Tools 3213 – Frequently Asked Questions
1) What bolt and nut size does the Klein 3213 spud wrench fit?
The Klein 3213 spud wrench has a 1-7/16 inch nominal opening, which is the across-flats size of a 7/8 inch U.S. Heavy hex nut. If your steel is bolted up with 7/8 inch heavy hex, this is the wrench. For other bolt diameters you need the matching opening, since a spud wrench is a single-size tool.
2) What is the difference between the Klein 3213 and 3213TT spud wrench?
Same wrench, two tie-off setups. The 3213 is the standard version. The 3213TT is built for tethering, so it can be lanyarded to a harness or anchor point for work at height where a dropped tool is a hazard. Ironworkers on elevated steel typically order the TT; ground-level and shop work does not need it.
3) What size bolt holes can the tapered handle line up?
The handle tapers from 1-1/8 inch down to 9/32 inch, so it will drift and align holes anywhere in that range without binding in the smaller ones. That taper is what makes a spud wrench a two-job tool: pin the connection with the handle, then turn the nut with the head.
4) Why is the head offset on this spud wrench, and does it help in tight connections?
The head sits at a 60 degree offset angle. That angle lets you get the opening onto a nut that is tucked against a gusset or flange and gives knuckle clearance when you swing the handle, which is the usual problem on built-up structural connections.
5) Is a spud wrench the right tool for running up structural bolts, or should I use an impact?
A spud wrench is a fit-up and hand-tightening tool: the tapered handle drifts the holes into line and the offset head snugs the heavy nut. For final tensioning of high-strength structural bolts crews use an impact or tensioning wrench. Think of the 3213 as the tool that gets the connection pinned and snug so the power tool can finish it.
6) Will this wrench hold up outdoors on bridge and exterior steel work?
It is forged alloy steel with a black oxide finish over a rust preventative, which is what you want for steel left in a bag or a bucket in the weather. Black oxide is a thin conversion coating, not a barrier like plating, so it still pays to wipe the tool down after wet work.
7) How do I tell this wrench apart from the other spud wrenches in the gang box?
Klein stamps the catalog number, bolt size and nominal opening right on the tool, so a crew carrying several openings can sort them by eye instead of trial-fitting nuts. On this one you are looking for the 1-7/16 inch opening and 7/8 inch bolt size markings.
