More info

With a maximum jaw adjustment of 38mm, this spanner also benefits from a raft of other features. The wide opening is ideal when you are working in a tight or awkward spot and the extra thin jaws also make it a versatile tool that will see many fastenings efficiently tightened or loosened.

But Bahco know that the wear and tear on the hand and wrist joint were problems that needed to be solved. And that’s why they came up with the ERGO range.

The thermoplastic cover distributes the pressure on the handle evenly across the palm, reducing the possibility of both slippage and strain on one area of your hand.

Superior build and quality of materials also mean that it complies with a raft of international and European standards. Everything about this adjustable spanner from Bahco oozes quality.

As well as this superb thermoplastic handle, the 38mm adjustable wrench also benefits from being forged in one piece (at a total length of 218mm), with a precision-hardened and anti-corrosion coating that means this tool will last a lifetime and more.
