Spanners

 

Tool/Equipment	Image	Appropriate Use	Auto Specific?
Torque Wrench		Tightening nuts and bolts to a specific torque. In some situations, for example, attaching wheels, the fastenings need to be tightened to a specific torque so they are not too loose or become damaged by being over tightened.	No
Box Spanners		General use of tightening nuts and bolts. Each end is a different size to reduce the total number of spanners required to cover a range of bolt sizes. The ends generally have 6 or 12 points to provide ease of use on hexagonal shape bolt heads.	No
Allen Spanners (Hex Keys)		To drive in bolts or screws with hexagonal sockets. They have the advantage of providing 6 contact surfaces during use.	No
Ratchet Box Spanner		Similar to a box spanner but more suitable in situations where rotational space is limited. The ratchet allows the spanner to be returned to its original position without the need for removing it from the fastening. Torque is applied in one direction, and free movement applies in the other direction.	No
Combination Spanners		General purpose spanners with the benefits of both box ends (multiple contact points) and open ends (easy access to fastener).	No
Offset Box Spanners		Similar to box spanners but with an offset end allowing easier application when the fastener is not very accessible.	No
Adjustable Spanner		Used for tightening nuts or bolts, or to hold fastenings. The jaw can be adjusted to allow use with multiple size fastenings. The shape of the jaws only allows for 3 contact surfaces at 90°, so if a hexagonal fastener is being used, only the 2 opposite surfaces will be in contact.	No
