Klein Tools 635-1/4 – Frequently Asked Questions

1) Can the Klein 635-1/4 nut driver be used on live electrical work?
No. The 635-1/4 is not insulated and will not protect against electrical shock, so keep it off energized work. For hot work you need a properly insulated 1000V-rated driver. Klein states the tool is not insulated and recommends approved eye protection during use.
2) Will this 1/4-inch nut driver work on a long bolt or threaded rod?
Yes. The shaft on the 635-1/4 is hollow, so the nut can run down a bolt of any length without bottoming out in the socket. Usable shaft length is 4 inches (10.2 cm), with 9 inches (22.9 cm) overall including the handle.
3) Does the magnetic tip actually hold a 1/4-inch nut or screw in place?
The tip is magnetic and holds the nut in the socket, which is what lets you start a fastener one-handed in a panel or box overhead. It is a 1/4-inch hex opening only, so it takes 1/4-inch nuts and hex-head screws.
4) How do I get more torque out of a Klein Cushion-Grip nut driver without stripping the nut?
The 635-1/4 has a wrench assist on the shaft, so you can put an open-end wrench on it and apply extra turning force by hand rather than leaning on the handle. The shaft is steel with the Cushion-Grip handle.
5) Is a 4-inch shaft nut driver long enough for work inside a panel or junction box?
For most panel and device-box work, yes. The 4-inch shaft and 9-inch overall length give reach into a box while still being short enough to maneuver in a cramped enclosure. If you need to reach deep behind equipment, step up to a longer-shaft 1/4-inch driver instead.
6) What does the red handle on this Klein nut driver mean?
Red is Klein's color code for the 1/4-inch size. Klein color-codes the Cushion-Grip handles so you can pull the right size out of a pouch or a shop set by sight instead of reading the shaft. Red here means 1/4 inch, not an insulation rating.
7) What is the exact part number and weight for the Klein 1/4-inch magnetic nut driver with the 4-inch shaft?
Order it as Klein Tools 635-1/4. It weighs 0.3 lbs, a single-model item with no finish or size options to pick.
