Klein Tools 32477 – Frequently Asked Questions

1) Can I use the Klein 32477 10-in-1 screwdriver on live electrical work?
No. The Klein Tools 32477 multi-bit screwdriver is not insulated, so it must not be used on energized conductors or terminals. For live work you need a tool rated and marked for 1000V insulated use. The 32477 is for de-energized panel, device and conduit fitting work.
2) Exactly which 10 bits and nut driver sizes come with the Klein 32477?
The 32477 covers ten tips in one handle: #1 and #2 Phillips, 1/4 inch and 3/16 inch slotted, T10 and T15 TORX, #1 and #2 square recess, plus 5/16 inch and 1/4 inch nut drivers built into the shaft. The 5/16 inch and 1/4 inch nut driver sizes are the two you hit most on electrical boxes, panel covers and strap screws, which is why this one tends to replace a handful of loose drivers in the pouch.
3) Will the Klein 32477 reach the screws at the back of a deep device box or panel?
Shank length is 4 inches with an overall length of 7.75 inches, which handles standard device boxes, panel covers and switchgear screws comfortably. For anything deeper than about 4 inches of reach, or a recessed screw in a tight chase, you want a long-shank driver instead.
4) Do the bits stay in the Klein 32477 when you pull it out of the fastener, or are they magnetic?
Bit retention is a quick-change mechanical system, not a magnet. The tool is listed as non-magnetic, so it will not pick up a dropped screw and it will not hold a loose screw on the tip. If you need a magnetic tip for one-handed work overhead, pair it with a magnetizer or a dedicated magnetic-tip driver.
5) Is a 10-in-1 multi-bit driver like the Klein 32477 the right choice, or should I carry individual screwdrivers?
A 10-in-1 is for service and troubleshooting work where you do not know what fastener you will meet: one handle, ten tips, Phillips through square recess plus two nut driver sizes. Where it loses out is heavy repetitive driving and odd reach needs, since a one-piece driver has no bit joint to flex and comes in lengths this 4 inch shank cannot match. Most electricians carry the multi-bit in the pouch and keep dedicated drivers in the bag.
6) Which Klein part number do I order for the 10-in-1 multi-bit screwdriver, and is it one tool or a kit?
Order Klein Tools 32477. It ships as a single tool with the bits included, not as a separate kit, and the shaft itself doubles as the 5/16 inch and 1/4 inch nut driver. Nothing else is required to use it.
7) Will the Klein 32477 drive the TORX and square-drive screws on equipment and racks?
It carries T10 and T15 TORX plus #1 and #2 square recess, which covers most control cabinet, rack and telecom equipment fasteners as well as deck and cabinet square-drive screws. Larger TORX sizes above T15 are not included, so check the head size on your equipment first.
8) What is the handle on the Klein 32477 like, and is it easy to spot in a tool bag?
Yellow and black Cushion-Grip handle, with a marking on the handle end so you can identify it looking down into a pouch or bucket. The cushioned grip is there for torque transfer on tight screws rather than just comfort.
9) How much does the Klein 32477 multi-bit driver weigh and will it fit a pouch?
It weighs 0.5 lb and measures 7.75 by 2.475 by 1.35 inches, so it drops into a standard driver pocket on an electrician's pouch without the bulk of carrying four or five separate drivers.
10) Is the shaft and bit set on the Klein 32477 steel?
Yes, steel construction throughout the shank and bits, with the Cushion-Grip handle over it. That matters on #2 Phillips and square recess work where a soft bit cams out and chews the screw head.
