Klein Tools JTH9E06 – Frequently Asked Questions
1) What hex sizes does the Klein Journeyman 9-inch T-handle hex key come in?
Eleven SAE sizes, all with the same 9-inch blade: 3/32, 7/64, 1/8, 9/64, 5/32, 3/16, 7/32, 1/4, 5/16, 3/8 and 1/2 inch. Part numbers run in order, JTH9E06 for the 3/32 through JTH9E17 for the 1/2 inch. Sizes are laser etched on the tool with Tip-Ident marking, so they stay readable after the paint would have worn off a stamped key.
2) Are these Klein T-handle hex keys inch or metric?
Inch. The sizing standard is SAE, so the fractional sizes from 3/32 up to 1/2 inch are what you get. If the fasteners on your equipment are metric hex, these will not seat properly, and a close-but-wrong fit is how you round out a socket head. Check the fastener before you order.
3) Will a 9-inch hex key reach recessed set screws down inside a panel or a coupling?
That is what the length is for. The blade measures 9 inches (22.9 cm) from the handle, so it reaches down into counterbored holes, through knockouts and into deep set-screw pockets on lugs and couplings without a socket extension. The trade-off is that a long blade flexes more than a stubby one, so keep the tool square to the fastener when you lean on it.
4) Is the grip safe to use on live electrical work?
No. The soft touch grip on the Journeyman T-handle is there for comfort and control, not electrical protection, and nothing in the specification rates it as insulated. For energized work you need a tool specifically rated and marked for it. Use these de-energized.
5) Can I really torque hard on a T-handle hex key without snapping the handle off?
The Journeyman T-handle uses a blade-through-handle design, meaning the steel shaft runs all the way through the grip rather than being pressed into a plastic socket. That is the detail that keeps the handle from spinning loose or separating under high torque. The crossbar also gives you two-hand leverage that an L-key cannot, which is why these get used on panel lugs and equipment assembly.
6) T-handle hex key or a standard L-key set for electrical work?
Pick the T-handle when the fastener needs real torque or you are working it repeatedly, like breaker lugs, ground bars and equipment set screws. The crossbar and soft touch grips let you push harder with less hand fatigue than a bare L-key, and the 9-inch blade gets you into recessed holes. An L-key set still wins for tight quarters where there is no room to swing a T-bar, and for carrying a full size range in a pouch.
7) Do I get a full set or one size per order?
Each Journeyman 9-inch T-handle is a single hex size with its own part number, so you order per size. MRO and facility buyers standardizing a shop usually pick up the sizes that match their equipment rather than the whole eleven, most commonly 1/8, 5/32, 3/16, 1/4 and 3/8 for electrical gear set screws and lugs.
8) Will these hex keys rust sitting in a service van or a damp mechanical room?
The blades are treated steel for rust and corrosion resistance, which is the point for tools that live in a van or a toolbox in an unconditioned building. Each one also has a hang hole, so they can go on a hook or a board rather than loose in a drawer.
