Open wrench

To choose well, check the size range you need and pick a durable material with a chrome-plated finish that resists wear. In this set, you’ll find open-end wrenches with sizes from 8 mm to 36 mm, including specific sizes such as 9 mm, 12 mm, 14 mm, 16 mm, 18 mm, 25 mm, 28 mm, and 32–36 mm. Choose an ergonomic handle and chrome finish for better durability during repeated use.

A serrated jaw grips the nut at multiple points, reducing wear on the edges and providing a safer hold than smooth jaws. This feature is included on several models in the series and is especially useful for plumbing, electrical work, and automotive maintenance—where surfaces may be smooth or damaged due to insufficient grip.

An open-end wrench is ideal for tight spaces and parts that require quick repositioning without needing to turn the tool around. It works perfectly for tightening or loosening nuts in common plumbing configurations or automotive maintenance jobs, where a socket wrench would require a larger turning motion.

After use, wipe them clean to remove residues, and apply a light oil to the joints and edges to prevent rust. Store them in a case or in a separate drawer to avoid impacts and scratches. Keep them dry and avoid very humid environments to preserve the chrome finish and gripping surfaces.

The sizes cover smaller formats like 8–9 mm up to larger sizes of 32–36 mm, with specific references for each tool. To build a practical assortment, include common sizes (for example 9, 12, 14, and 17–18 mm) and add one or two larger sizes depending on your most frequent projects—so you don’t end up missing a needed tool during work.

Chrome models provide better resistance to corrosion and increased durability, which is essential for humid environments and repeated repair tasks. The chrome finish also makes cleaning easier and helps remove dirt, supporting a strong grip and extending tool life even after intensive use across different applications.
