Klein Tools 32307 – Frequently Asked Questions

1) Which tamperproof bits come with the Klein 32307 27-in-1 screwdriver?
The Klein 32307 carries 26 bits plus a 1/4-inch nut driver in the handle. Torx tamperproof: T7, T8, T10, T15, T20, T25, T27, T30, T40. Tamperproof hex: 3/32, 7/64, 1/8, 9/64, 5/32 (4 mm), 3/16, 2 mm, 2.5 mm, 3 mm, 5 mm. TORQ-SET: TS6, TS8, TS10. Tamperproof spanner: SP4, SP6, SP8, SP10.
2) Will this Klein driver turn the security Torx screws with the pin in the middle of the head?
Yes. The Torx bits on the 32307 are tamperproof (pin-in-Torx) style, so they have the center hole that clears the pin on security Torx fasteners, in T7, T8, T10, T15, T20, T25, T27, T30 and T40. The hex and spanner bits are likewise tamperproof versions.
3) Is the Klein 32307 tamperproof screwdriver insulated for live electrical work?
No. The 32307 is not insulated, and the barrel is stainless steel. Don't use it on energized conductors or inside a live panel. For work that requires insulated tools, look for a Klein driver rated to 1000V instead. The cushion grip here is for comfort, not electrical protection.
4) How long is the shank on the Klein 32307, and will it reach into a recessed security fastener?
Shank length is 3.38 inches (8.6 cm) with an overall length of 8.49 inches (21.6 cm) and a 5 inch handle. That gives you a little over three inches of reach past the handle, enough for normal panel screws and enclosure covers but not for deeply counterbored or tube-recessed fasteners. Barrel and handle measure 1.42 inches across, so it needs that much clearance around the fastener.
5) Do the bits stay in the handle, or do I need a separate bit case?
No separate case needed. All 26 tamperproof bits and the 1/4-inch nut driver store inside the handle on rare-earth magnets, and the bits are double-sided so each one carries two sizes. The chuck is magnetic as well, which holds the bit in place and lets the tip hang onto a loose screw while you start it.
6) Is one 27-in-1 tamperproof driver enough, or should I buy an individual security bit set?
For service and access work, the 32307 covers the four families you actually hit in the field, pin-in-Torx, tamperproof hex in both inch and metric, TORQ-SET and spanner, in one tool you can carry in a pouch (0.55 lbs, 8.49 inches long). A loose bit set plus a separate handle gives you more sizes but goes back in the truck. If you only ever open one fastener type, a dedicated driver in that size is faster; if you're opening unknown enclosures, the multi-bit is the one to carry.
7) Can I use this on security screws in an alarm panel or camera enclosure?
That's the intended use. Klein lists the 32307 for tamperproof and security bit driving, and the spanner (SP4 through SP10) and pin-in-Torx sizes are the ones typically used on alarm panels, camera housings, control boxes and public-space enclosures. One caution for integrators: since it isn't insulated, back the panel power off before working near live terminals.
8) Does the Klein 32307 include metric tamperproof hex sizes or just inch?
Both. Inch tamperproof hex covers 3/32, 7/64, 1/8, 9/64, 5/32 and 3/16; metric covers 2 mm, 2.5 mm, 3 mm, 4 mm and 5 mm. That matters on imported equipment and telecom gear where the security hex fasteners are metric.
9) What is the Klein part number for the 27-in-1 tamperproof multi-bit screwdriver?
Klein Tools model 32307. It's the black and yellow cushion grip multi-bit tamperproof driver with a stainless steel barrel.
