Heavy-duty hook wrench crafted from chrome-vanadium steel with a polished chrome finish; designed for adjusting and removing external ring nuts. The hook profile covers a broad range of ring nut sizes, reducing the need for multiple fixed wrenches. Replaceable round noses allow onsite maintenance and extend service life. Four size variants cover 15–180 mm ring nut diameters with working lengths from 6.5 in to 19.3 in, matching common industrial bearing and housing applications. Robust handle geometry provides secure engagement and efficient torque transfer while minimising slippage.
