High-Torque Nut Drivers
The exact color of the black oxide blade finish may vary.
Apply High Torque
The handle's three-sided geometry directly engages the structure of your hand, instead of relying on friction with your skin, so you can apply high force with less fatigue.
Spin Fasteners Quickly
Round sections at the front and back ends of the handle allow you to spin long, finely threaded fasteners quickly and continuously.
Durable, Nonslip Handle
The overmolded grip provides a nonslip surface that is permanently bonded to the handle and won't degrade or become sticky over time.

Tip type and size are printed on the end of the driver for easy identification.
A minimum 1 inch recess inside the shaft accommodates excess threaded tails of long bolts or studs
Materials and Construction
AISI 4037 Steel Shaft
- Strong alloy steel hardened to HRC 41–46
- Black oxide finish—keep lightly oiled for best corrosion protection
- Reinforced with calcium carbonate for dimensional stability
- Shore D 68 durometer
- Soft thermoplastic elastomer (TPE)
- Shore A 80 durometer
Insert Molded for Exceptional Strength
We use a molding process that forms the handle around the blade, rather than forcing the blade into a premade handle. The result is a straighter blade that can’t twist out.
