Double open ended spanner

The CHANGLU TOOLS double open-end wrench is a versatile hand tool designed for tightening and loosening hexagonal nuts and bolt heads.

It features two open ends of different sizes, allowing one wrench to be used with two different fastener dimensions.

The open-end design provides convenient side access to fasteners, particularly in locations where a ring spanner or socket is difficult to use.

The wrenches are specified as complying with DIN 3110, a standard defining dimensional and construction requirements for double open-end wrenches.

A wide selection of sizes is available, ranging from 8 × 9 mm to 75 × 80 mm, making it possible to select the right tool for both smaller mechanical tasks and larger fastening components.

These wrenches are suitable for automotive workshops, industrial equipment maintenance, agricultural machinery repairs, structural assembly and general mechanical work.

Each wrench is sold individually, with the required size combination selected as a product variant.

Two Sizes in One Tool

The double open-end wrench features two different-sized ends, allowing users to work with two fastener sizes using a single tool.

This reduces the need for frequent tool changes and makes repetitive assembly and repair tasks more convenient.

Open-End Design for Convenient Access

The open ends allow fasteners to be accessed from the side.

This is particularly useful when working:

• with nuts on long threaded rods;

• on pipework and mechanical assemblies;

• in structures with limited access from above;

• with fasteners that cannot be reached using closed sockets.

DIN 3110 Standard

The manufacturer specifies DIN 3110, a standard applicable to double open-end wrenches.

Standardised dimensions help users select the correct tool for metric hexagonal nuts and bolt heads.

Wide Range of Sizes

Available size combinations range from 8 × 9 mm to 75 × 80 mm.

Smaller sizes are suitable for compact mechanical and assembly work, while larger sizes are intended for heavy-duty fastening components used in machinery and industrial structures.

Versatile Applications

CHANGLU TOOLS double open-end wrenches are used across a wide range of repair and maintenance tasks.
