The British-accepted unit of measure for length is inch, which is actively used as a dimensional parameter, including threaded fasteners. Its differences are quite significant in comparison with the metric system used by manufacturers in the Russian Federation and other countries. But, due to the fact that a sufficient amount of technical means entering the country from abroad is completed (assembled) using the inch format of connecting threaded elements, these products are in high demand among domestic consumers. You can find the required inch fasteners using the company's website https://krepcom.ru /catalog /dyuymovyy_krepezh /bolty-vinty / implementing it in Russia. These are the main parameters for choosing in the catalog. Access to it is free and does not require prior registration.
Common parameters for classification
Almost all threaded elements made in the form of bolts, nuts, studs and even pipes should be referred to the format of threaded fittings with an inch dimension. This system is used in the production of a wide variety of technical means by such industry giants as the USA, China, Canada, Japan and South Korea. The abbreviation of its classification has the following generally accepted and obligatory designation:
- UTS - the thread has the shape of a cylinder with a top angle of 60 degrees.
- BSW is a classic British standard. The angle of the vertex itself is 55 degrees.
- NPT - this parameter can be used for both tapered and cylindrical threads with a top angle of 60 degrees (mainly used for sealed pipe connections).
Inch designation of thread dimensions has a more complex (in comparison with the metric analogue) format. You can deal with it and choose the best fitting option for fasteners using the online classifier of the KREPKOM online resource. For an individual consultation, the site provides the option of contacting a technical manager who, in a chat format or by phone, will answer all questions that arose during the selection process.
