Open End Wrenches

Open end wrenches are among the most common tools both in professional environments and households. Their functioning is very simple and, substantially, it is a basic application of the leverage principle: with just a minimum effort, they allow you to tighten or loosen a fastener. Typically, these tools feature open ends of various shapes and sizes to fit all the available nuts and bolts. They are placed around the fastener, and torque is applied manually. Also, they can be used in combination with another wrench or screwdriver to keep the fastener in place while twisting it on or off.

Open end wrenches are available in various designs. The most typical one features an open end at each side of the tool, each carrying a different size. The other most common design has just one open end and is often combined with a box end. The shape can be square, hex, or have tailored conformations to meet specific requirements. The most typical materials are steel and chrome-vanadium alloys. In some cases, colored finishes ensure quick identification. Wrenches are classified according to SAE, metric, or Army Navy standards and sold individually or in sets. Visit our online store for a broad selection of reliable and robust open end wrenches.
