Bahco ERGO Screwdrivers have been developed according to the scientific ERGO process. The high-performance alloy steel blade has been chrome plated and entirely hardened for high protection against corrosion, a long life tool. A black oxide tip provides higher accuracy. A three-component handle provides maximum user comfort. The soft material with ridged surface provides superior grip and greater force transmission. A flat face prevents the screwdriver from rolling away. It's easy to choose the right tip, thanks to the colour-coded handle and permanent symbol on the domed end.
