The wera 9 piece stainless steel colour coded ball end hexagon allen key set is a professional grade metric hex key set designed specifically for working with stainless steel fasteners and applications where rust contamination is a concern. Manufactured from stainless steel throughout, this allen key set prevents the transfer of extraneous rust particles to sensitive components – an essential consideration when working with stainless steel screws in food preparation equipment, marine environments, or hygiene critical installations. The innovative hex plus profile provides increased contact surface area within the screw head, significantly reducing cam out and virtually eliminating damage to fasteners even under high torque application. Each key features a ball end on the long arm, enabling you to work at angles up to 25 degrees from the screw axis – ideal for accessing recessed or awkwardly positioned fixings where a straight approach isn't possible. The wera take it easy colour coding system allows instant size identification, whilst the colour coded sleeves maintain excellent grip even in cold conditions. The wear resistant clip holder keeps all nine keys organised and readily accessible, covering the most commonly used metric sizes from 1.5mm through to 10mm.
