The range of Kincrome Spanners has undergone exhaustive independent testing, is now 80% stronger than the ASME (American Society of Mechanical Engineers Standard) and 130% stronger than the German DIN standard. The stronger, lighter and greatly enhanced quality of the Kincrome spanner range leaves many name brand competitors in its wake. Improved features include a thinner head allowing the spanner to reach tighter areas, a rounder shaft for a more comfortable grip when applying greater torque, a lighter weight, and the shorter length decreases radial movement by up to 20%. Construction of the range is from forged Chrome Vanadium Steel (Cr-V) hardened, tempered and chrome plated with a slight satin finish for corrosion protection. Increased Molybdenum Manganese and Nickel content provide greater strength and corrosion resistance.
