Spanner Nut - Sierra Marine Engine Parts - 18-3751 (118-3751)


The spanner is most famous for its use as a tool or a wrench that offers a mechanical advantage while twisting things and other crucial tasks. They are precise tools used for a variety of everyday tasks as well as in professional settings. Vehicle spanners are a distinct set of tools with unique purposes and methods for a specific range of duties used by numerous industries.

In addition to maintaining the stability offered by a ring head, flare nut spanners can fit fasteners that ring spanners cannot. The spanner goes with flare fittings, also known as hexagonal nuts and fittings. They are for use with affixed fasteners to tubes, such as the ends of plumbing or brake pipes. They have an open head rather than a closed loop. Thus, they resemble box or ratchet wrenches visually.
