An essential piece of kit for aeronautical engineers and mechanics, or when you need a firm grip on screws and nuts, this Bahco 3/4” combination ratchet spanner offers everything you need.

The open end has a 15° angle that improves access to bolts as well as improving grip. The internal ratchet ring also promotes grip, which reduces slippage.

Cross-threading is a common issue but the 12 point dynamic-drive profile minimises this, meaning that screws and nuts have a longer life.

It also has a quick direction-change system – simply move the fingertip leaver from left to right or vice versa, all of which can be done without the need to detach from the bolt, nut or screw.

With clear markings as to size on the combination ratchet spanner, picking up the wrong tool is a thing of the past. The chrome-plated matte surface also makes for easier grip. The straight handle allows for better grip when you need it most. At 247mm in length, it fits into the small spaces that you will often be faced with but without compromising on grip.

A high-quality alloy steel tool that conforms to both ISO 1711-1 and DIN 3113 meeting minimal values for torsional strength and torque values for combination wrenches.
