Klein Tools GN3243 Gooseneck Hex Connecting Bar

The GN3243 runs 29-1/4 inches overall (74.3 cm) and weighs 4 pounds (1.8 kg), with a 7/8 inch hex body. That is a one-hand-carry bar for an ironworker's belt or a bolt bag, long enough to get real leverage on a beam connection without being a two-hand pry bar.

Two different jobs on one bar. One end is a forged fit-up point, which you drive into a bolt hole to drag two pieces of steel into alignment so the bolts start. The other end is a chisel, set at a 45 degree angle so you get leverage when you pry a beam into position rather than bottoming the bar flat against the steel. If all you do is align holes, a plain spud wrench or drift pin covers it; the chisel end is what makes this a positioning tool as well.

The GN3243 body is 7/8 inch, and the fit-up end tapers to a point from there, so it enters holes punched for 3/4 inch and 7/8 inch structural bolts and seats as it goes in. That taper is the whole point of a fit-up bar: it wedges and pulls the plies into line instead of sliding through. On oversize or slotted holes it will still draw the connection, it just seats deeper.

Yes, the GN3243 is US made and forged. For agencies and institutional buyers working under domestic sourcing requirements on a steel package, that is the answer that usually decides whether the tool can go on the purchase order at all.

GN3243 is the number to order, and it is a single configuration, no length or finish options to pick. Klein sells it as the gooseneck hex connecting bar.

Yes, and Klein states it on the GN3243 itself: always wear approved eye protection. You are driving a forged point into a bolt hole and prying against hardened steel, so chips and scale come off. That is the one PPE call that goes with this tool.
