The bahco s18hex 18 piece 1 2 drive hexagon socket bit set is a comprehensive socket bit collection designed for professional mechanics and engineers working with hex fasteners. This metric socket set features high performance alloy steel construction with a matt finish, providing the durability required for regular workshop use. The dynamic drive™ profile incorporated into each socket protects against wear and damage, helping to extend the working life of both the sockets and the fasteners they engage. This design feature is particularly valuable when working with softer materials or in high torque applications where conventional sockets might cause rounding or deformation. The set includes both short and long hex ball bit sockets across nine popular sizes from 4mm to 17mm, offering versatility for accessing recessed fasteners and working in restricted spaces. The ball end design allows for angled engagement, making it ideal for automotive repairs, machinery maintenance, and equipment servicing where straight line access isn't always possible. All components are supplied in an oil and temperature resistant polypropylene case, ensuring the set remains organised and protected in demanding workshop environments.
