The wera 9 piece chrome plated hex plus key set metric is a professional l-key set designed for driving 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 inside the screw head compared to a standard hex key. This design significantly reduces notching and the risk of rounding out the screw recess, making it ideal for use in situations where screw preservation matters such as in mechanical assembly, automotive work, and precision engineering tasks. The ball-end on the long arm of each key allows for angled entry, enabling reliable working even where access is restricted or awkward. Chrome plating across all nine keys provides strong corrosion resistance, while laser-engraved size markings ensure each key remains clearly identifiable throughout its working life. The set is housed in a wear-resistant clip holder that keeps all nine keys securely stored and easy to remove individually. Sizes range from 1.5Mm through to 10mm, covering the most commonly encountered metric hex socket screws in professional use.
