Key Features

Anti-Slip Grip

The anti-slip wrench design delivers up to 400% more gripping power, which helps reduce fastener damage and puts more turning force where you need it.

Long Forged Reach

Long panel forging gives you better reach and leverage, which matters when the fastener sits below surrounding parts or needs extra force to break loose.

Combination Wrench Size

This DeWalt combination wrench gives you a 13/16 inch SAE opening in a single hand tool, so you can switch between open-end access and box-end engagement on the same fastener size.

Overview

The DeWalt DWMT72200OSP 13/16-In (21-mm) Standard (SAE) Combination Wrench is a single-size hand wrench built for turning 13/16 inch SAE fasteners. This is a combination wrench designed for tightening and loosening SAE fasteners. Model Number: DWMT72200OSP. If you need a straightforward mechanic’s wrench with better bite on worn or stubborn hardware, this one is built around grip and leverage instead of gimmicks.

The big selling point here is the anti-slip design. DeWalt rates it for up to 400% more gripping power, which matters for two reasons on real work: it helps the wrench stay planted on the flats of the fastener, and it lowers the chance of rounding corners when you lean on it. That is the kind of feature that pays off most when you are dealing with older hardware, limited access, or fasteners that have already seen a few wrong-sized tools.

The long panel forging gives this combination wrench more reach and more leverage than a stubby pattern wrench. In practical terms, that means better access past surrounding components and a little more mechanical advantage when a nut or bolt does not want to move. For mechanics, maintenance work, equipment service, and general shop use, that extra length is usually more useful than a flashy finish.

Because it is a combination wrench, you get two useful working ends in one tool. The open end is the faster option when you need to slip onto a fastener from the side and reposition quickly. The box end is the better choice when you want fuller contact and more control under load. That makes this a sensible choice for repeated service work where speed and secure engagement both matter.

This is an individual wrench, not a set piece pulled from a kit. If you already have a drawer full of tools but keep reaching for this exact size, buying the DeWalt DWMT72200OSP 13/16-In (21-mm) Standard (SAE) Combination Wrench on its own makes more sense than replacing an entire set. It is also a solid add-on for anyone building out an SAE mechanic’s wrench lineup one size at a time.

Who should buy it? Anyone doing automotive service, equipment maintenance, garage work, farm repairs, or general fastening jobs that call for a 13/16 inch SAE wrench. If that size comes up often in your work and you want better grip plus a longer forged body for leverage, this is the kind of hand tool that earns its place fast.

Built to Hold on Better

This wrench is built for users who care more about clean engagement and usable leverage than filler features. The anti-slip geometry and long forged body make it a practical choice for repeated service work.
