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, [1] 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:.

To ensure compatibility and ease of maintenance, threads are standardized. For existing and new applications, it is necessary to identify the thread type to guarantee a proper connection of the joint. The BSP, or Whitworth thread, is a family of thread standards that has been adopted internationally, except in the United States. For a thread that conforms to BSP, the major diameter of the pipe thread is slightly smaller than the actual OD of the pipe, and the minor diameter will be very close to smaller than the inside diameter of the female thread. There are two types of BSP threads:.

Please select your country! This section covers threading formulas and definitions for how to calculate cutting speed, feed rate or any other parameter for your thread turning, thread milling or tapping operations. You also find the designation for different thread forms according to international standards. By dividing the full cutting depth of the thread into smaller cuts, the sensitive nose radius of the insert is not overloaded. Example: By taking 0. The infeed can be calculated according to the formula:. The distance from a point on the screw thread to a corresponding point on the next thread measured parallel to the axis.

General information

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 протянул руку.  - El anillo. Кольцо. Беккер смотрел на него в полном недоумении. Человек сунул руку в карман и, вытащив пистолет, нацелил его Беккеру в голову. - El anillo.

Она понимала, что найти принадлежащую Хейлу копию ключа будет очень трудно. Найти ее на одном из жестких дисков - все равно что отыскать носок в спальне размером со штат Техас. Компьютерные поисковые системы работают, только если вы знаете, что ищете; этот пароль - некая неопределенность. К счастью, поскольку сотрудникам шифровалки приходилось иметь дело с огромным количеством достаточно неопределенных материалов, они разработали сложную процедуру так называемого неортодоксального поиска. Такой поиск, по существу, представляет собой команду компьютеру просмотреть все строки знаков на жестком диске, сравнить их с данными громадного по объему словаря и пометить те из них, которые кажутся бессмысленными или произвольными. Это сложнейшая работа, заключающаяся в постоянном отсеивании лишнего, но она вполне выполнима.

Когда Халохот поднимался по лестнице, Беккер, спустившись на три пролета, вылез через один из проемов и повис на руках. Сделал он это как раз вовремя - убийца промчался мимо в ту же секунду. Он так торопился, что не заметил побелевших костяшек пальцев, вцепившихся в оконный выступ. Свисая из окна, Беккер благодарил Бога за ежедневные занятия теннисом и двадцатиминутные упражнения на аппарате Наутилус, подготовившие его мускулатуру к запредельным нагрузкам. Увы, теперь, несмотря на силу рук, он не мог подтянуться, чтобы влезть обратно. Плечи его отчаянно болели, а грубый камень не обеспечивал достаточного захвата и впивался в кончики пальцев подобно битому стеклу.
