Whitworth British standard thread gauges

Whitworth gauges are indispensable tools in the inch measuring system, where the control of the clearance between internal and external threads is considered an extremely important task. These specialized measuring tools play a key role in ensuring accuracy and ratio between male and female threads used in various industries and engineering.

Whitworth gauges belong to the inch system of measurement, which distinguishes them from the metric standards used in many other countries. This causes a difference in measurements and standards for thread connections.

These tools got their name in honor of the English engineer and inventor Joseph Whitworth, who actively developed the standardization of thread connections in the middle of the 19th century. For the first time, these standards were introduced in Great Britain to facilitate the production and maintenance of machines and equipment.

We manufacture gauges to check threads of tapped holes to receive wire threads inserts / STI for BSW / BSF / Whits Threads

Whitworth gauges have a sequence of standard sizes, including diameters and thread pitches. This sequence of sizes makes it easy to choose the right tool for a particular thread connection. Each gauge has precisely defined thread diameters and pitches, allowing for accurate measurement and comparison of thread connections. To achieve accurate results, it is important to use the correct gauge for a specific standard.

The Whitworth gauge system includes different types:

BSW - British Standard Whitworth: This type of thread is used for general applications and is the main part of the Whitworth system.

BSF- British Standard Fine: This type of thread has a higher degree of precision and is used where greater control over tolerance is required.

BSB - British Standard Brass: This type of thread is intended for use in the manufacture of brass products and has its own characteristics.

**Whits **- this category includes special diameters and the number of threads per inch, which are not included in the usual standards, and require individual control.

Whitworth gauges are an important tool for ensuring quality and accuracy in mechanical manufacturing in the inch system. They help to ensure compliance of products with standards and to ensure uninterrupted operation of threaded connections.

Widely used in the manufacture, repair and maintenance of thread connections, in particular in the mechanical engineering, automotive industry, shipbuilding, as well as in industries where the ability to accurately measure and maintain the standards of thread connections is important. Whitworth gauges can also be used in specialized industries such as antique restoration, where the thread connections of old-time products may require special attention and precision in the repair work.
