Miniature Adjustable Wrench

adjustable wrench
An adjustable spanner or adjustable wrench is a spanner (wrench) with a "jaw" of adjustable width, allowing it to be used with different sizes of fastener head (nut, bolt, etc.). Compare to an ordinary spanner, which is of fixed size, and requires a different spanner for each fastener size.

Comes in two styles: locking and non-locking. Non-locking styles feature an adjustable end opening with little provision made for slippage.
