Klein Tools SS8 – Frequently Asked Questions

1) Will a Klein SS8 stubby nut driver reach a 1/4-inch nut inside a crowded panel where a full-length driver won't fit?
That is what the SS8 is built for. Overall length is 3.75 inches (9.5 cm) with a 1.5 inch (3.8 cm) shaft, so the whole tool is shorter than the shank on a standard nut driver. It drives 1/4 inch hex fasteners only. The tradeoff is leverage and depth of reach: with a 1-1/2 inch shaft you can only engage a nut sitting close to the surface, so for recessed studs deep in a box you still want a full-length driver.
2) What does the hollow shaft on the Klein SS8 nut driver actually do for me?
The shaft is hollow rather than solid, so a long threaded stud or bolt end can pass up inside it. That matters when you are running a nut down a long stud, or working stacked circuit boards and standoffs where the thread protrudes past the nut. A solid-shaft driver stops as soon as it bottoms on the thread. Internal flanges anchor the shaft in the handle so it resists twisting under torque.
3) What is the difference between the Klein SS8 stubby nut driver and the Milwaukee 49-66-4533 SHOCKWAVE impact nut driver?
They are different tools for different drives. The Klein SS8 is a hand-driven nut driver with a 1/4-inch hex opening, a 1-1/2-inch hollow shaft and a 3.75-inch overall length with a red plastic grip handle. The Milwaukee 49-66-4533 is a SHOCKWAVE Power Groove impact duty nut driver in 5/16 inch by 2-9/16 inch, magnetic, made to be chucked into a driver rather than turned by hand. If the fastener is 1/4-inch hex and you are reaching into a panel by hand, the SS8 is the match; if you are running 5/16-inch fasteners off an impact driver, the Milwaukee is the one.
4) I need a magnetic nut driver to hold the screw - does the Klein SS8 do that?
The Klein SS8 is not magnetic; it relies on its 1/4-inch hollow shaft to capture the fastener, which also lets it pass over long bolt ends and stacked circuit board standoffs. If magnetic fastener retention is the deciding feature, the Milwaukee 49-66-4533 SHOCKWAVE Power Groove nut driver is magnetic, in 5/16 inch by 2-9/16 inch.
5) Is the shaft on the Klein SS8 magnetic so it holds the nut?
No, the SS8 has no magnetized tip. The hollow 1/4 inch shaft holds the nut by fit alone, so expect to start fasteners by hand overhead. If you need a magnetic driver for one-handed starts, the Milwaukee 49-66-4533 SHOCKWAVE is a magnetic nut driver, though it is 5/16 inch and a 2-9/16 inch impact-duty bit rather than a stubby hand driver.
6) Which Klein part number do I order for the 1/4-inch stubby hollow-shaft nut driver?
Order Klein Tools SS8. It is a single-configuration item, one size (1/4 inch) and one handle color (red), so there is nothing else to specify on the order line.
7) Does the Klein SS8 meet tool standards for government and institutional purchasing, and where is it made?
Klein states the SS8 meets or exceeds applicable ASME/ANSI specifications, and country of origin is the United States, which matters on Buy American sensitive purchase orders.
8) Can I use the Klein SS8 in an impact driver or drill?
No. The SS8 is a one-piece hand tool with a plastic grip handle on a chrome-plated steel shaft, 3.75 inches overall, meant to be turned by hand in tight quarters. For powered driving you need a bit-style driver such as the Milwaukee 49-66-4533 SHOCKWAVE Power Groove impact duty nut driver, which is built for that service.
9) My fasteners are 5/16-inch hex heads - will the Klein SS8 fit them?
No, the SS8 is a 1/4-inch nut driver only. For 5/16-inch hex head fasteners, the Milwaukee 49-66-4533 is a 5/16-inch by 2-9/16-inch nut driver. Keep in mind the SS8 is a hand tool while that Milwaukee is an impact duty driver bit.
10) Will the chrome shaft hold up in damp mechanical rooms and service trucks?
The shaft is chrome plated over steel for corrosion resistance, which is the usual answer for tools that live in a truck bin or a damp plant. The handle is plastic grip, so there is no wood or cork to swell.
11) For a tool pouch or a standardized MRO kit, how much room and weight does the SS8 add?
Very little. The driver weighs 2.4 oz (68 g) and measures 3.75 by 1 by 1 inch, so it drops into a pouch pocket or a drawer insert without taking a full-length driver slot. Handles are color coded red, which makes it quick to pick out of a shared kit.
12) Is the Klein SS8 safe for live electrical work, or do I need a different driver?
The SS8 is not an insulated tool, so it is not intended for work on energized conductors; it is a general electrical department hand driver for panel, junction box and control panel work once the circuit is de-energized. The Milwaukee 49-66-4533 SHOCKWAVE nut driver is likewise not an insulated hand tool - it is an impact duty driver. For live work you need a driver specifically rated and marked for insulated use.
