The Wera 3335 series parallel slotted tip screwdrivers have a blade manufactured from 100% stainless steel, yet equally strong as conventional steel screwdrivers. They are ideal for industrial applications as they prevents extraneous rust forming on stainless steel fastenings due to contamination. The Wera Lasertip grips into the screw head for safer screwdriving and less effort. The multi-component Kraftform handle is uniquely designed around the hand during screwdriver use, reducing fatigue and increasing speed. Soft zones offer improved grip, hard zones allow easy hand repositioning.Size 4.0 x 100mm
