This is a set of nine high-quality hex keys from Allen. Each key in this set is equipped with a ball end, allowing an entry angle up to 25° in the screw to work in hard-to-reach areas. These specific keys utilize the metric measurement system. These are the go-to hex keys we prefer to use when metric is involved!
Each hex key is composed of a black oxide-finished, tempered steel alloy and comes in a noninterference, hinged "caddy" to provide easy access. All hex keys are precision-formed to exact dimensional tolerances for precise fit.
