Klein Tools 633 – Frequently Asked Questions

1) What sizes come in the Klein Tools 633 nut driver set?
The 633 set includes four SAE nut drivers: 630-1/4, 630-5/16, 630-3/8 and 630-9/16. All are inch sizes, not metric, so if your fasteners are metric this set won't cover them.
2) Can these nut drivers run down a long threaded rod or stacked standoffs?
Yes. Each of the four drivers has a full hollow 3 inch (7.6 cm) shaft, so a long bolt or threaded rod passes straight up through the shaft. That's what makes them usable on stacked circuit boards and long-bolt work where a socket would bottom out. Depth of pass-through is limited to the 3 inch shaft length.
3) Is the Klein 633 nut driver set made in the USA?
Yes, the 633 nut drivers are made in the USA, which matters on institutional and government orders carrying domestic-sourcing requirements.
4) What is the correct Klein part number to order for this four-piece hollow shaft set?
Order Klein Tools 633. That single number covers the complete four-driver set with 3 inch hollow shafts; the individual drivers inside it carry their own numbers (630-1/4 through 630-9/16) if you ever need to replace just one.
5) How do you tell the nut driver sizes apart quickly in a pouch?
Klein's Tip-Ident marks the handle end with color coding that shows both the hex size and the orientation of the socket, so you can pick the right driver out of a pouch and line it up on the fastener without rolling the tool over to read a stamp. Useful on a panel where you are cycling between 1/4 and 5/16 all day.
6) Will the shafts rust or bind in a damp service truck?
The shafts are chrome plated for corrosion resistance and a smoother feel, and internal flanges anchor the shaft in the handle to resist twisting loose under torque. The Cushion-Grip handles are built for higher torque and comfort on repeated turns.
7) How much space does the Klein 633 set take up in a tool bag, and what does it weigh?
The set measures 13.375 x 4.375 x 1 inches and weighs 1.3 lbs, so it lies flat in a bag pocket or drawer rather than taking up bucket space.
