Ergo-Fold Key Sets feature a composite grip handle shaped for superior ergonomics. A soft cushion-grip insert offers comfort and slip resistance, while a hard shell provides maximum strength. Eklind keys provide extra reach for safer clearance from your work. Eklind Ergo Key Sets can be used at a right angle to generate maximum torque. Also they be used as a screwdriver when fully extended to a firm stop. As with all other Eklind Hex Key Products, We use the highest quality 8650 Chrome Nickel Alloy Hex Steel that is heat treated for superior strength and finished to resist rust.
