An offset double ring ratchet spanner is a type of hand tool that is used to turn bolts and nuts

An offset double ring ratchet spanner is a type of hand tool that is used to turn bolts and nuts. It is a combination of a ratchet wrench and a double ring spanner. The offset design of the tool allows for better access to bolts and nuts in tight spaces or difficult-to-reach areas.

The double ring spanner part of the tool features two rings, one at the end of the handle and one at the end of the shank, that allow for a better grip on the bolt or nut. The ratchet mechanism allows the user to turn the bolt or nut in one direction without having to remove and reposition the tool. This feature allows for a faster and more efficient work, as it eliminates the need for repeatedly repositioning the tool.

This tool is commonly used in the automotive, machinery and heavy equipment maintenance, construction and manufacturing industries. It can be used to tighten or loosen bolts and nuts of various sizes and is compatible with both standard and metric measurements. The offset double ring ratchet spanner comes in different sizes and can be made of different materials such as Chrome-vanadium steel, alloy steel, and titanium.
