About this product
The Faithfull FAIHK20MLA is a 2.0mm long arm hexagon key measuring 83mm in length, suited to fine precision work such as small electronics, precision instruments, optical equipment and delicate mechanical assemblies. It is made from fully hardened chrome vanadium steel, which helps the key maintain its precise dimensions over extended use. The long arm design gives improved reach and leverage compared with a standard short key, making it easier to work on tight fixings without damaging delicate components. Faithfull hexagon keys are also commonly used on machinery, domestic appliances and cycles for driving socket screws.
