Combination wrenches serve a central purpose for any craftsman’s work. Their dual use with a box end and an open end lends them flexibility. This wrench in particular is made to tighten fasteners 1-¼” in size. Renting combination wrenches saves time and energy, especially in situations where individual wrenches have been lost from a set. The box end grips the sides of the fastener for slip-free use. Whether you’re a professional mechanic or a homeowner performing DIY repairs, you will always find a need for a combination wrench.
