The 99 series of hook wrenches have a square nose designed specifically to engage the notches in UNI/ISO 2982 and 2983 ring nuts. The fixed hook end fits precisely into the slots of these fasteners, providing a firm grip and reducing the risk of slippage or damage. The square nose of these spanner wrenches adds versatility, allowing the wrench to be used in applications requiring a flat surface for added leverage or alignment. Made from high-strength alloy steel, these wrenches offer excellent durability and resistance to wear, making them ideal for heavy-duty industrial, automotive, and mechanical maintenance tasks. Their compact design and ergonomic handle ensure ease of use in tight or awkward spaces, delivering both precision and reliability. These spanner-type wrenches have a chrome-plated, rough textured finish that hides scratches. The Beta series number and size are molded into the side of the handle for quick identification and a hole at the end of the handle can be used to hang the wrench from a hook or a lanyard. This wrench fits 22mm, 25mm, and 28mm size ring nuts. Measures 136mm long overall x 21mm wide x 4mm thick and the nose is 1.8mm deep.
