Double End Open Spanner MM Jhaveri

An open-end spanner, also known as an open-ended wrench or spanner, is a hand tool used to grip and turn nuts and bolts. It typically has two U-shaped jaws at each end, with both jaws being of different sizes but typically of the same size on either end of the tool. The jaws are designed to fit around the flat sides of a nut or bolt.

The tool’s design allows it to provide a firm grip on the fastener, making it easier to tighten or loosen bolts or nuts. Open-end spanners come in various sizes to accommodate different nut and bolt sizes. They are commonly used in automotive repair, construction, plumbing, and various mechanical applications.

One of the primary advantages of an open-end spanner is its ability to work in tight spaces where a socket wrench might not fit. However, its grip might be less secure compared to other wrench types like the box-end wrench or socket wrench, which cover the fastener’s sides more fully.

Users need to be cautious as using an open-end spanner incorrectly or with excessive force might damage the fastener or slip, potentially causing injury.
