About this product
The Faithfull FAIHK100MLA is a 10mm long arm hexagon key made from fully hardened chrome vanadium steel, giving durable, long-lasting performance. It is designed for driving socket screws and is suited to heavy-duty applications such as machinery and industrial equipment, as well as general use on appliances and cycles. The long arm design provides increased leverage, making it easier to loosen or tighten recessed fixings. The key has chamfered edges to protect both the fitting and the tool from damage, and the size is clearly marked for easy identification. It measures 170mm in length.
