The wera 9 piece blacklaser hex plus key set imperial is a professional-grade l-key set designed for use with imperial hexagonal socket screws, supplied in a durable clip holder for organised, accessible storage on site. The hex-plus profile is a key differentiator for tradespeople working with socket head screws. By offering a larger contact surface within the screw head, it significantly reduces notching and virtually eliminates the risk of damaging the recess extending the working life of both the key and the fastener. The blacklaser surface treatment provides strong corrosion resistance and long service life, making these l-keys well suited to demanding workshop and site environments. Laser-engraved size markings are wear-resistant, ensuring quick and reliable key identification throughout the life of the tool. The ball-end on the long arm allows for angled working, ideal for reaching fasteners in awkward or restricted access situations. The wear-resistant clip holder keeps all nine keys securely stored and ready to hand, making this set a practical choice for engineers, mechanics, and contractors working with imperial fasteners.
