Hex nuts (also known as hexagonal nuts) are one of the most commonly used nuts in the mechanical engineering industry. For decades, hex nuts have been an essential component in the assembly of machine parts that require proper fastening and high operational reliability. Many countries, including Japan, have standards governing the specifications of these nuts. This article will focus on the Japanese JIS standard and discuss what it entails for hex nuts.

As part of quality assurance and functional testing, testing technology plays a crucial role in the production environment. A variety of material testing methods are used—ranging from destructive tests, such as tensile testing, to non-destructive techniques, such as ultrasonic testing. This article provides a comprehensive overview of the requirements for testing technology as well as various testing methods.

Reliable test methods are essential in electronics manufacturing. Spring contact pins serve as a precise interface for testing connections in electronic assemblies. But how exactly are spring contact pins used and which variants are available? In this article, you'll discover the many uses and different designs of these precise testing tools.

Corrosion is much more than just superficial rust. When incompatible metals are joined, their direct contact can cause profound damage due to galvanic corrosion. The process behind galvanic corrosion is based on electrochemical processes and preferentially occurs in wet, salty, or aggressive environments. Under these conditions, it leads to the inevitable degradation of the less noble metal. In this article, we show how contact corrosion works, which materials are particularly affected and which preventive measures are effective.

Pneumatic cylinders are versatile drive elements that produce precise linear motion by using compressed air. Depending on the application, different technical properties are required. For example, vacuum valves with volumetric flow restrictors enable precise control of airflow, while integrated anti-rotation devices increase operational reliability. But how do I choose the right compressed air cylinder for my application? This article gives you a comprehensive overview of what is involved when selecting pneumatic cylinders or compressed air cylinders so that you can make informed decisions in the future and select the cylinder that best suits your needs.

From locking, positioning to ejecting - spring plungers are small but crucial components in machines, fixtures and automated systems. Their variety of designs, materials and mounting styles makes them extremely versatile - but also require explanation. In this article, you will obtain a practical overview of the most important functions, types and materials as well as valuable information on the correct selection and professional installation.

When components are manufactured within tight tolerances, the precise handling of micrometers is very important. But correct reading has to be learned: What scales are there? What does the reference line show? And how is the measurand actually determined? In our current blog post, micrometers are explained in detail. We show you step by step how to read analog micrometers correctly – with hands-on examples, typical sources of error and tips from manufacturing engineering.

How much compressed air does a pneumatic cylinder really need? In this article, you'll learn how to calculate the air consumption of double-acting cylinders and which influencing factors are critical. In industrial applications of pneumatic systems, precise analysis of air demand is essential to conserve energy and increase plant efficiency. In practical terms, we show what matters in the calculation, including the formula, an example, and tips for optimization.
