Klein Tools S20 – Frequently Asked Questions
1) Can the Klein S20 nut driver go over a long bolt or threaded stud?
Yes. The S20 has a hollow shank, so the bolt or stud passes up inside the shaft instead of bottoming out on the nut. That is what makes it work on stacked circuit boards, panel standoffs, and long-thread applications where a solid-shank driver stops short. The hollow section runs the full 4 inch shaft length.
2) Is the Klein S20 nut driver safe to use on live electrical work?
No. The S20 is not insulated and will not protect against electrical shock. For energized work you need a driver rated and marked as insulated. Klein's insulated nut drivers carry a different designation and are sold separately; the S20 is a standard uninsulated tool for de-energized work.
3) Will the Klein S20 hold the nut on the driver by itself?
No, it is not magnetized. You will need to start the nut by hand or hold it in place. A hollow shank driver cannot use a captive magnet in the base the way a solid shank one can, since the bore has to stay clear for the bolt to pass through.
4) How do I tell the 5/8 inch Klein nut driver apart from the rest of my set in a pouch?
By the handle color. The S20 has a red Comfordome handle, and Klein color-codes each size so you can pick the right one out of a pouch without reading the stamp. The handles are smooth-domed to sit in the palm for higher torque.
5) Will the shaft on the Klein S20 spin loose in the handle under torque?
The shaft is anchored with internal flanges molded into the handle, which is what resists the shaft twisting free when you lean on a tight nut. The shaft is also chrome-plated against corrosion, and the tool meets or exceeds applicable ASME/ANSI specifications. Made in the USA.
6) What is the part number and weight on the 5/8 inch Klein hollow shank nut driver?
Klein Tools model S20, MPN S20, weighing 4.8 oz (136 g). It ships as a single tool, not part of a set.
