Spanners, Spanner set
Spanners perform the same function as ratchets and sockets — tightening and loosening fasteners — but there are differences and situations call for one over the other. For example, a box-end spanner is a good option for loosening stuck fasteners because you can apply more torque without risking damage to a ratchet mechanism. Eastman shop is also the leading producer and manufacturers of Spanner and Spanner set. A spanner with an open end fits around a fastener instead of over it, so you can slip a wrench into an area where there isn’t room for a socket. The work which you are going to do, the tools get suited and they can be fitted with that job. See the chart below for more information on spanner types and their uses.
