Klein Tools 630-7/16M – Frequently Asked Questions

1) What is the difference between Klein 630-7/16 and 630-7/16M?
Both are 7/16-inch cushion-grip nut drivers with a 3-inch hollow shaft. The 630-7/16 is the standard tip; the 630-7/16M has the rare-earth magnetic tip that holds the fastener on the driver so you can start a nut one-handed in a panel. If you are pulling sheet metal screws and hex-head fasteners out of tight enclosures, order the M.
2) Will a hollow shaft nut driver work on a long threaded bolt or stud?
Yes, that is the point of the design. The shaft is hollow the full 3 inches, so a long bolt or stud passes up inside the shaft instead of bottoming out on the tip. On non-hollow (solid) nut drivers you run out of travel as soon as the thread hits the end. Practical limit here is the 3-inch shaft depth.
3) Is this Klein 7/16 nut driver insulated for live electrical work?
No. It is not insulated and carries no voltage rating, so it must not be used on or near energized conductors. For live work you need a Klein 1000V insulated nut driver instead. This one is for de-energized panel, HVAC and equipment assembly work.
4) Can I put this nut driver in a drill or impact driver?
No. This is a hand tool with a fixed rubber cushion-grip handle, not a bit, so there is no hex shank to chuck up. It is built for hand torque, with the rubber grip giving you more turning force by hand. For powered driving you want a separate 7/16 magnetic nut setter bit.
5) How do I tell the 7/16 apart from the other sizes in a Klein nut driver set?
By the color on the handle dome. The 7/16-inch driver is coded brown, so in a pouch or a rack you pick it out by color rather than reading the stamp. If you are standardizing a maintenance crew's kits, that color coding is what keeps the sizes from getting mixed up.
6) What is the shaft made of and will it twist loose from the handle?
Steel shaft, anchored into the handle with internal flanges that Klein specifies as a twist-resistant anchor, which is the joint that usually fails first on cheaper nut drivers when you lean on a seized fastener.
