M4, for example, means the "standard" M4 thread size: for a bolt, the outside of the thread would be 4mm in diameter, and the spacing between threads the pitch would be 0. There are 'non-standard' M4 thread forms, which will have different pitches, which are incompatible with standard M4.
For example M4x0. This would be referred to as "M4 fine", but some people would refer to any M4 pitch less than 0. Smaller than M4 you readily risk breaking taps in your workpiece taps are harder than drill bits, so this might mean you've ruined your workpiece. There are alternatives threads to metric threads, such as UK imperial threads, the US has a different set of imperial threads, there are special Model Engineer threads, special Cycle threads.
Pipe threads are common though beware, the diameters of pipe threads refer to the internal diameters of the pipe, not the outside diameter of the thread as are BA British Association threads. Find out the correct hole size to drill for the thread you wish to tap standard metric tapping drill sizes: M4 x0. Use a centre punch mark to centre the drill point. Drill a hole smaller than the measure needed for the tap Put some Rocol cutting compound on the end of the tap.
Holding the level and square to the material turn the tap wrench until the first cut into the material has been made. Keep turning until all the way through the material and most of the way through the thread, there should be no resistance once the cut has been made the full distance through the material when turning in or out using the tap wrench.
Once through the material using this tap repeat the process using the tap with 2 grooves and then finally again using the tap with no grooves. Check the threading using the approparate sized bolt. Tighten up the screw on the die holder to keep the die in place, ensure all the screws fit in the indences in the die.
Put some Rocol cutting greese on the end of the rod to be threaded, Place the rod in a vice square and tighten, use a set square to ensure the rod is square in the vice. Place the dice on top of the rod and turn to create the first cut. Keep turning until the depth of thread is achieved, there should be no resistance once the cut has been made level and squre to the rod Check the threading using the approparate sized nut.

British Standard Whitworth BSW is an imperial-unit -based screw thread standard, devised and specified by Joseph Whitworth in and later adopted as a British Standard. The Whitworth thread was the world's first national screw thread standard,  devised and specified by Joseph Whitworth in 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. The thread pitch increases with diameter in steps specified on a chart. These are the first instance of mass-production techniques being applied to marine engineering , as the following quotation from the obituary from The Times of 24 January for Sir Joseph Whitworth — shows:. The Crimean War began, and Sir Charles Napier demanded of the Admiralty gunboats, each with engines of 60 horsepower , for the campaign of in the Baltic.
WHITWORTH AND OTHER BRITISH THREADS
Corresponds to the Metric Thread in its type of use. British Association Standard Thread. Used mainly for instruments and clocks.
With so many different thread forms used around the World it can quite often be quite difficult to establish the exact thread required, This information, however, is absolutely vital, particularly where reverse engineering takes place to replace bolts that may have been in use for decades. This data sheet helps you by listing all metric and inch imperial threads so you can see the number of threads per inch alongside a metric thread pitch so you can now immediately see what the likely thread is. Naturally this is an everyday tool for the experts at Hague Fasteners, but we think it only fair to share our handy reference guide with the Engineering Sector and associated industries, with our compliments. Hague Fasteners have been manufacturing every conceivable thread form since there formation in It is such a rare thing in these modern times to find a Fastener manufacturer that has such history and such extensive expertise.

Он искал глазами Сьюзан Флетчер, но она уже стояла прямо перед экраном, на котором крупным планом было видно лицо Дэвида Беккера. - Дэвид. - Привет, красавица. - Он улыбнулся.
Однако она отлично знала, чем занимался Хейл. Он был законченным компьютерным маньяком. Вопреки правилам он часто проникал в шифровалку в уик-энд, чтобы на мощнейших компьютерах погонять программу, над которой работал. - Вот хочу попробовать сделать кое-какую перенастройку да проверить электронную почту, - сказал Хейл.
