Klein Tools S818 – Frequently Asked Questions
1) Is the Klein S818 a hollow shaft nut driver that can pass a long bolt through it?
Yes. The shaft is hollow, so a long threaded rod or protruding bolt can pass up through it instead of bottoming out. That's the difference that matters when you're working stacked circuit boards, standoffs, or any assembly where the stud runs well past the nut.
2) What size nut does the Klein S818 driver fit?
It drives 1/4 inch hex nuts. One size only, so if you're working a mixed panel you'll want the matching sizes from the same super-long series alongside it. Klein color codes the Comfordome handles across the line, which makes grabbing the right size out of a pouch fast.
3) Should I use a super-long nut driver like this or a 1/4 inch socket on an extension?
A socket and extension gives you a ratchet and swappable sizes, but it needs swing room and the joint can flex or drop the socket in a blind cavity. The S818 is one solid piece from handle to tip, hollow through, so it feeds straight down a long stud and stays put where you can't see or reach. For electricians pulling panel covers and terminal nuts down a raceway, the one-piece driver is usually faster. Keep the sockets for anything needing real torque or a ratcheting action.
4) Does the Klein S818 meet a recognized hand tool standard for facility and institutional purchasing?
It meets or exceeds applicable ASME/ANSI specifications, which is the dimensional and performance standard normally cited on hand tool submittals for MRO and government purchasing.
5) What is the exact Klein part number to order for the 1/4 inch 18 inch nut driver?
Order Klein Tools S818. That's the 1/4 inch super-long nut driver with the 18 inch hollow shank, and it's the full manufacturer part number, no suffix to specify.
6) Does the Klein S818 handle hold up to solvents and shop chemicals?
The handle is break resistant and impervious to most acids and alkalis, so incidental contact with shop chemicals won't degrade it. It's full fluted for grip and driving torque, with chamfered edges and a full-size top that has no unfinished seams or sharp edges digging into your palm on repeated turns.
