Klein Tools 647M – Frequently Asked Questions

1) What sizes come in the Klein Tools 647M magnetic nut driver set?
The 647M set covers seven SAE sizes: 3/16, 1/4, 5/16, 11/32, 3/8, 7/16 and 1/2 inch. These are inch (SAE) hex sizes, not metric, so for metric nuts and sheet metal screws you need a separate metric set.
2) Are these Klein nut drivers hollow shaft so they can run down a long bolt or threaded rod?
Yes on six of the seven. The 647M drivers have full hollow shafts, with the 3/16 inch the one exception, so they will pass over long bolts and threaded rod as you drive the nut down. Shafts are 6 inches, which sets how much protruding thread you can swallow.
3) Will the magnetic tip actually hold a sheet metal screw or nut while I start it one-handed?
That is what the tip is for. Each driver in the 647M uses a rare-earth magnet in the hex socket, so the fastener stays seated while you reach into a box, duct or machine frame one-handed. Useful on overhead HVAC and panel work where a dropped nut means pulling the cover again.
4) Is a 6-inch shaft nut driver too long for tight junction box work?
The 6-inch shaft trades maneuverability for reach. It is the right pick for deep sockets, recessed studs and getting past standoffs or wiring in HVAC cabinets. In a shallow box or close to a wall, a 3-inch stubby shaft handles it better. The 647M is the long-reach set.
5) What is the Klein part number for the 7-piece 6-inch magnetic nut driver set?
Order it as Klein Tools 647M. That is the single model covering the full 7-piece, 6-inch magnetic set.
6) How do I tell the sizes apart quickly on the 647M nut drivers?
Each handle has a color-coded dome, so you can pick the size out of a pouch by color rather than reading the stamp. Handles are Cushion-Grip for torque transfer and comfort on repeated runs of self-tappers.
7) How much space does the Klein 647M set take up in a tool bag or van drawer?
Figure on 15.75 x 6.75 x 1.5 inches and 1.5 lbs for the set as supplied. That footprint lays flat in a van drawer or slides into the back pocket of a tool bag.
8) Will the shafts rust or the handles spin loose on the Klein 647M?
Shafts are chrome plated for corrosion and wear resistance, and the handles use internal flanges that anchor the shaft against twisting, which is the usual failure point on a nut driver under high torque. Made in USA.
