Klein Tools 65129 – Frequently Asked Questions
1) Does the Klein 2-in-1 hex nut driver cover both 1/4 inch and 5/16 inch nuts with one tool?
Yes. The Slide Drive hex nut driver carries both a 1/4 inch and a 5/16 inch tip in one shaft, and you switch between them by twisting the thumb nut to slide the tip and lock it in place. Those are the two sizes that cover most sheet metal screws, panel nuts and HVAC hex-head fasteners, so it replaces two separate nut drivers in the pouch.
2) What is the difference between Klein 65129 and 65131 hex nut drivers?
Shank length is the only difference. Model 65129 is the 6 inch version, giving reach down into deep junction boxes, across a panel gutter or past obstructions. Model 65131 is the 1-1/2 inch stubby, for working close to a wall or inside a tight enclosure where a long shank won't clear. Both use the same 1/4 inch and 5/16 inch Slide Drive tips.
3) Will this hex driver hold the nut on by itself so I can start a fastener one-handed?
Yes, the tip is magnetic and holds the fastener in either the 1/4 inch or 5/16 inch position. That matters when you are starting a sheet metal screw overhead or dropping a nut into a live panel where you cannot afford to lose it in the enclosure.
4) Should I get the stubby 1-1/2 inch or the 6 inch Klein Slide Drive nut driver for electrical panel work?
Pick by clearance, not by preference. For panel and junction box assembly where the fastener sits recessed or behind wiring, the 6 inch shank (model 65129) gets the tip to the nut without your hand fouling the box. For tight cabinet interiors, disconnects, or work against a stud where you cannot swing a full-length driver, the 1-1/2 inch shank (model 65131) is the one that fits. Many electricians carry both, since the tool covers both nut sizes either way.
5) Is the Klein Slide Drive nut driver a hollow-shaft driver that will pass over a long threaded stud?
No. This is a solid-shank magnetic hex nut driver with a sliding dual-size tip, not a hollow-shaft driver. If you need to run a nut down a long piece of protruding threaded rod or a stud, you want a hollow-shaft nut driver instead, since this tip will bottom out on the thread end.
6) What kind of handle is on the Klein 2-in-1 hex nut driver, and can I get real torque on a tight nut with it?
It uses Klein's Cushion-Grip handle, shaped to transfer torque and stay comfortable through repeated fastening. For high-volume work like racking equipment or setting box covers all day, that grip is what keeps the hand from wearing out; it is a hand driver though, not an impact tool.
7) Can the tip change size accidentally while I am turning a fastener?
The tip position locks. A thumb nut twists to set and hold the selected size, so the shaft stays at 1/4 inch or 5/16 inch while you drive rather than slipping mid-turn. Change sizes deliberately by loosening that nut and sliding the tip.
8) What trades and jobs is this 2-in-1 magnetic hex nut driver meant for?
It is built as an electrical tool first: panel and junction box assembly, commercial and residential rough-in and trim, plus data and telecom rack work. HVAC techs use the same two sizes for sheet metal and equipment panels, and it carries over to industrial equipment servicing and general MRO. For a maintenance crew standardizing a tool list, one of these covers what two fixed nut drivers used to.
