The wera tool check 7 piece modular hex plus 1 l hexagon allen key set is a compact 7-piece metric hex key set designed for use with hexagonal socket screws across a wide range of trade and workshop applications. At the heart of this set is wera's hex-plus profile, which increases the contact surface area within the screw head. This significantly reduces the notch effect and virtually eliminates the risk of rounding off or damaging screw heads a particular advantage when working with fasteners that are heavily torqued or frequently adjusted. All seven l-keys feature a thorough chrome-plated finish, providing robust corrosion resistance and a long service life even in demanding site conditions. Laser-engraved size markings ensure each key is quickly and easily identified without the markings wearing away over time. The set is housed within the tool-check modular system and includes an adapter 9549 that allows it to be connected to other tool-check modular components. This makes it ideal for contractors and engineers looking to build a customised, modular toolkit that grows with their needs.
