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.

Grease
Cleaners & Solvents

Easy-to-Read Markings

Tip type and size are printed on the end of the driver for easy identification.

Slotted Tip

Machined tip is the same width as the shaft to fit into narrow recesses

Thick tip design withstands high-torque driving and light-duty prying

Materials and Construction

AISI 8650 Steel Blade

Strong Ni-Cr-Mo alloy hardened to HRC 52–56
Chrome-plated shaft finish for increased corrosion resistance

Polypropylene Handle

Reinforced with calcium carbonate for dimensional stability
Shore D 68 durometer

Overmolded Grip

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.
