Crowfoot spanners with square drive

A crowfoot spanner is an open or ring-shaped spanner head with a square drive instead of a handle. That lets you slide it onto a ratchet, torque wrench or extension and reach nuts and bolts in places an ordinary spanner cannot. Fitters in automotive, machine and installation work use them to undo connections that sit deep out of reach, for example pipe couplings along an engine block.

Because the head works in line with the drive, you can combine it with a torque wrench for a controlled tightening torque. Brands such as Bahco and Facom offer versions for both hex nuts and tapered pipe nuts, in sizes that run here from roughly 8 to 50 mm. When choosing, look at the drive size of your ratchet, often 3/8 or 1/2 inch, and at the spanner widths you need most.

A crowfoot spanner set in rising sizes covers most jobs in one go. Choose hardened versions that hold their fit under high torque. This way you safely undo even the trickiest connection.
