The magneto spanner is the ideal solution for small nut bolts. It is a collection of small, connected single-end spanners in different sizes that are usually distinguished via numbers, with 8 being the largest spanner and 1 being the smallest. Adjustable wrenches ought to be calibrated for width settings on a regular basis, and certainly before starting a new job (even if the fasteners you’re dealing with are the same size as the last time you used the spanner) Keep adjustable spanners and wrenches clean

The types of size guides you need to bear in mind will be slightly different when choosing and buying either an adjustable or a non-adjustable wrench. Standard spanners will carry a single size rating, whereas adjustable versions will define a specific range of fastener sizes that the tool in question was designed to accommodate.These spanners can range between 100mm-750mm long, and they can fit onto hexagonal fasteners sized between 4mm-210mm. If you want to use a ring spanner for a square fastener, increase the size of the fastener head by 25%. This number is the size of the required spanner. Unlike most spanners, the crows foot spanner has no handle. It is shaped like an open-end spanner but has no shaft, making it ideal for use where 6pt and 12pt spanners can’t reach. To extend the length, it can be combined with a ratchet, or to apply extra force, a torque wrench may be used. Crows foot spanner sets are also available.

Monkey wrenches are another type of adjustable spanner with a long history; the origin of the name is not entirely clear, but Geesin reports that it originated in Britain with a fancied resemblance of the wrench's jaws to that of a monkey's face, and that the many convoluted folk etymologies that later developed were baseless. [3] Before the Bahco/Johansson/Crescent type became widespread in the United States, during the industrial era of the 1860s to the 1910s, various monkey wrench types were the dominant form of adjustable wrench there. There should never be more than a millimetre of play as an absolute maximum - if there is, you’re not using the right size wrench When in use, the box spanner fits over the top of the fastener, meaning it touches all edges of the nut or bolt, and the Tommy bar is used to tighten or loosen it. The spanner’s size can be measured in various ways, such as Whitworth, BA, metric and imperial AF (across flats) sizes.

Turn the screw mechanism on the tool to open or close the spanner (i.e. to alter the width gap between its jaws) to the required setting. Depending on which way you turn the screw mechanism, the jaws of the spanner will begin to open or close accordingly (it’s almost always the smaller lower jaw that actually moves, in relation to the static upper jaw which remains fixed in place.) Third Step There are many forms of adjustable spanners; many of them are screw-adjusted, whereas others use levers, and some early ones used wedges. Slogging spanners, such as the Bahco 100mm Slogging Spanner, tighten a nut after they are initially tightened manually. The fastener’s elasticity is established using index markers, and this works out the torque required. If you’re placing so much weight on the tool means it is not unlikely that the tool could slip violently or the fastener could suddenly give way.

The double ended spanner has two open-end heads, one at each end, and is the most commonly used spanner available. The ends are angled at 15-30 degrees, and the handle is both flat and slim. This tool is made for use with rotary fasteners. Andreas Bergh (31 July 2014). Sweden and the Revival of the Capitalist Welfare State. Edward Elgar Publishing. pp.11–. ISBN 978-1-78347-350-2. Similar to pipe wrenches, JP realised that nuts and bolts, too, required different sizes of tool to tighten and loosen them. His idea of an adjustable spanner came to light and would bring him worldwide fame in years to come. However, he was not the original inventor of the adjustable spanner. The first one was created by Joseph Stubs, 50 years earlier. JP improved the original tool design by giving it only one moveable jaw and it was sold and loved all over the world ever since. If you have Torx fasteners, Torx spanners (or Torx spanner sets) can be used to loosen or tighten them. The head (or both heads) resembles a 6-point star and it is designed to not slip whilst tightening a fastener. It should also prevent cam-out from the person using this tool when requiring heavy torque.

Avoid using hammers, mallets or other striking tools to apply extra torque to any type of spanner that isn’t explicitly designed and built for that purpose (most adjustable wrenches are not) The ratchet spanner can be between 90mm-425mm long, with the length increasing with the size of the head, and the ratchet head sizes are between 4mm-36mm. However, if you need to reduce the size, some of these spanners have interchangeable heads or bushes that can fit onto a larger head size.

The open end is stronger than the ringed end because it applies less pressure on the weakest parts of the nuts or bolts, which are thought to be the corners. It is also good for the first turns when loosening a fastener, or for the last turns to tighten one. In contrast, the looped end can be flexible, depending on the combination spanner, and can be ratcheted or non-ratcheted. Most spanners of this kind are designed for hexagonally shaped nuts and bolts. The box spanner is a small metal tube with holes drilled at a perpendicular angle into the metal. The Tommy bar, also known as the T-bar, can then be inserted through the holes so the spanner can be turned. You need a Tommy bar to use the box spanner, as it enables you to turn the spanner like a tap. In between uses, store them away securely in an appropriate container or tool box to have the best chance of keeping the tools dry and free from excessive grease, grime or rust Think about the area you’re working in, and any potential hazards it may pose to you or to other people in the vicinity while completing the task. This can include: Heamar offer several Torx spanners, including the Stahlwille E20 & E24 Double Ended Torx Spanner, which is suitable for heavy use and is manufactured using chrome alloy steel.

For fasteners that have no faces, the hook spanner is designed to tighten and loosen nuts with a periphery with no holes. For example, Stahlwille Adjustable 20mm-42mm Hook Spanner is an adjustable tool that ranges between 20mm-42mm and weighs 90g. This is a plumbing tool designed to use on fasteners for baths and basins. The basin spanner has two asymmetrical jaws connected to a long shaft, and there is a handle at the other end. As shown through the Bahco 10mm-32mm Basin Spanner, one of the jaws is curved and closes around the nut or bolt due to the jaw being spring-loaded. The other jaw is connected to a spanner. When someone turns the shaft, it applies torque to the fastener. Once you’ve got the tool to grip the fastener as tightly as required, proceed much as you would with any other, non-adjustable spanner: turn the fastener right to tighten it, or left to loosen it
