An adjustable spanner (UK and most other English-speaking countries), shifting spanner (Australia and New Zealand),[1] English wrench (Turkey)[2] or adjustable wrench (US and Canada) is any of various styles of spanner (wrench) with a movable jaw, allowing it to be used with different sizes of fastener head (nut, bolt, etc.) rather than just one fastener size, as with a conventional fixed spanner.[3]
