Klein Tools JTH9M5 – Frequently Asked Questions

1) Is the Klein JTH9M5 T-handle hex key metric or SAE?
Metric. The JTH9M5 drives a 5 mm hex socket, and the size is laser etched on the blade so it stays readable after the blade gets dirty. If you're working on SAE fasteners you need an inch-sized T-handle instead; this one will round out a close-but-not-equal SAE socket.
2) Can I use the Klein JTH9M5 hex key on live electrical work?
No. The JTH9M5 is not insulated and will not protect against electrical shock. De-energize and verify before you work, and use an insulated tool rated for the task if the circuit may be live. Klein also calls for approved eye protection when using it.
3) How deep a recessed set screw can the 9-inch Klein T-handle hex key reach?
The blade is 9 inches (22.9 cm) long, so it reaches set screws well down inside a pulley bore, coupling, or panelboard bus connection that a standard L-key can't get to. The end is chamfered, which helps you start the blade into the socket when you can't see it.
4) Will a T-handle hex key give me more torque than a folding or L-shaped hex set?
Yes, and that's the main reason to pick one. The JTH9M5 uses a blade-through-handle construction, so torque goes straight from the crossbar into the blade rather than through a pinned or crimped joint. The T-bar also gives you two hands on the tool for breaking loose a seized 5 mm set screw, which an L-key's short leg won't do comfortably.
5) Does the Klein JTH9M5 come as a set or a single size?
Single size only. The JTH9M5 is one 5 mm T-handle key, ordered by that part number. If you need to cover a range of metric sizes across a facility, you buy each size as its own Journeyman T-handle rather than a boxed assortment.
6) Will the Klein JTH9M5 hex key rust if it lives in a damp truck box?
The blade is treated steel for rust and corrosion resistance, so it holds up to a job box or van that sees humidity and temperature swings. There's also a hang hole in the handle if you'd rather keep it on a panel hook or shadow board.
