Description

The widely used (except in the US) British Standard Pipe thread, as defined by the ISO228 standard (formerly BS-2779), uses Whitworth standard thread form. Even in the United States, personal computer liquid cooling components use the G 1⁄ 4 thread from this series. [ citation needed] Macy’s cardholders must activate their Macy’s Card.

They essentially have the same purpose: to tighten and loosen nuts and bolts. Nevertheless, they have distinct characteristics designed for specific use cases. Ratchet spanner sets are often among the more expensive types of spanner kits, but their handy added functionality makes them easily one of the most popular designs found in both professional and enthusiast tool kits the world over.

They’re comfortable to use and the heaviest on test. Not so good were the three spanners (we tested only the conventional sizes) that were marginally oversize. But it’s a versatile set and ideal if you need the range. Wood, J. (1977) (50m)˜ The restoration and preservation of vintage & classic cars", Yeovil: Haynes, ISBN 0-85429-186-5 It is always important to use the correct fitting spanner. Otherwise, the excess play exerted may slip the spanner and cause damage to the bolt or nut or cause personal injury. Fixed size spanners would, therefore, be preferred every time an appropriate is size is available. Here are spanner types you need to know

BS and BSW sizes are often seen on old tools. In some countries they're still in common use, and Whitworth is still used here for some niche applications. You need to remember the important term “across flats”. For instance, if you get a spanner marked saying 1/2 AF, it is supposed to mean the spanner is made to fit on a fastening that is 1/2 inch wide or just across flats i.e. A.F. The spanner may simply be indicated as 1/2 or as 1/2 SAE while some are marked as .50 SAE (the decimal equivalents of the 1/2 inch) for instance. Another important thing to note is that the thread on the bolt should either be UNC or UNF but the spanner tends to carry the head size measurements inscribed on it, it is all simple stuff. It’s therefore important to keep the project that you’re working on in mind as that’s likely to dictate if you need to head down the imperial or metric route with your hand tools – or a mixture of both. 3. Knowing your terms can help you to find the right tool For the British Association (BA) configured threads, as often used on old electrical equipment, the inscribed/marked size is also the head size. For example, a 2BA spanner can comfortably fit on a 2BA nut. Wrenches and Spanners are tools designed and used to grip screwed components (mainly nuts, pipe connectors, and bolts) to loosen or tighten them.

These threads are designated by a number between 1/16 and 6 that originates from the nominal internal diameter (i/d) in inches of a steel pipe for which these threads were designed. These pipe thread designations do not refer to any thread diameter. The Whitworth thread was the world's first national screw thread standard, [1] devised and specified by Joseph Whitworth in 1841. Until then, the only standardization was what little had been done by individual people and companies, with some companies' in-house standards spreading a bit within their industries. Whitworth's new standard specified a 55° thread angle and a thread depth of 0.640327 p and a radius of 0.137329 p, where p is the pitch. The thread pitch increases with diameter in steps specified on a chart. If you want to use old tools as a regular part of a set of metric tools, remarking them in mm makes life easier.
