Klein Tools 516PNDHC – Frequently Asked Questions

1) Is the Klein 516PNDHC safe to use on live electrical work?
No. The 516PNDHC is not insulated and will not protect against electrical shock. Klein is explicit about it in the product warnings. If you're working energized, you need a tool rated and marked for insulated use, not this one. It's also not for prying or chiseling, and eye protection is called for.
2) I lost the 5/16 driver out of my Klein 32950 set. Is this the right replacement?
Yes. Klein lists the 516PNDHC as the replacement piece for the 5/16 inch position in the Magnetic Color-Coded Power Nut Setter Set, Cat. No. 32950. Ordering it individually gets you the same yellow-coded, hollow, impact-rated driver rather than repurchasing the whole set.
3) Will this 5/16 nut setter hold up in an impact driver?
Yes, the 516PNDHC is impact rated, so it's built for use in an impact driver rather than just a drill. It's steel alloy with a corrosion resistant finish. Standard practice still applies: don't use it to pry, and wear eye protection.
4) Does this nut driver hold the screw by itself so I can work one-handed?
It does. A rare-earth magnet sized specifically to the 5/16 inch hex holds the fastener in the socket, so you can start a self-drilling screw or hex-head sheet metal screw overhead or up a ladder without a second hand on it.
5) How long is the Klein 516PNDHC and will it reach into a deep box or channel?
Overall it's 6.3 inches with a 5 inch shaft, which is an extended length compared with a standard stubby nut setter. That gets the chuck clear of strut channel, deep junction boxes, and recessed hex heads. Shank profile is about 0.49 inches across, and the tool weighs 0.13 lbs.
6) Is a hollow nut setter better than a solid one for general electrical work?
Depends on the fastener. A hollow driver like the 516PNDHC is what you want where the screw or rod protrudes past the nut, threaded rod, long self-drillers, tek screws through thick decking, since the shaft swallows the excess. A solid magnetic setter is fine for short hex-head screws and is the simpler pick if you never run nuts on all-thread. Buying the hollow version covers both cases.
7) What does the yellow band on the Klein 516PNDHC mean?
Yellow is Klein's color code for the 5/16 inch size in the Magnetic Color-Coded Power Nut Driver line. The double line lets you grab the right size out of a pouch or a set without measuring. Sizing is SAE, not metric.
