Regular price
Key Features:
- Klein Tools 661 square-recess screwdriver with a #1 tip and a 4" (10.2 cm) round shank
- 7.75" (19.7 cm) overall length, weighing 3.2 oz (91 g)
- Works on most combination-head receptacle, switch and panel screws
- Heat-treated, chrome-plated shaft with a precision-machined tip; black Cushion-Grip handle with Tip-Ident color coding
- Meets or exceeds applicable ASME/ANSI specifications; made in USA (non-insulated, non-magnetic)
Benefits:
- The #1 square-recess tip seats fully in combination-head device screws, so it cams out less than a slotted or Phillips driver
- Tip-Ident on the handle end lets you grab the right driver and read tip orientation out of a pouch without turning it over
- The Cushion-Grip handle lets you apply more turning torque comfortably through a long day of device work
- Internal handle flanges anchor the blade against twisting, and chrome plating resists corrosion in a damp van
- Compliance with applicable ASME/ANSI specs gives a documented benchmark when comparing it against an unmarked driver
