Square Recess High-Torque Screwdrivers
Unique three‐sided handles combine maximum power with smooth speed.
The exact color of the black oxide blade finish may vary.
Versatile Handle Design
Generate Higher Torque
The three-sided middle section of the handle leverages the structure of your hand to generate higher turning power longer.
Spin Fasteners Quickly
The round shape at the front and back ends of the handle allow you to spin fasteners quickly and continuously.
Durable, Nonslip Handle
The overmolded grip provides a soft, 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.
Precisely Formed Square Tip
- The Square tip geometry is milled to precise tolerances for an exact fit with fasteners.
- Made from strong, heat-treated steel so that the tips hold their shape over time.
Materials + Construction
AISI 8650 Steel Blade
- Strong nickel, chromium, molybdenum alloy hardened to HRC 52-56
- 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.
