JIS and DIN hex socket screws - A comparison

Hex socket screws are an indispensable component in the assembly and construction of machinery and equipment. They are used worldwide, with each country having its own standards for size, thread, and materials. One of the most popular standards is the Japanese Industrial Standard (JIS). In this blog post, we will take an in-depth look at hex socket screws and the Japanese JIS standard.

Hex Nuts - JIS-standardized hex nuts with selection information

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.

Couplings - Rigid couplings

Rigid, non-disengageable couplings are axially aligned, compact, and non-rotating, making them widely used. They create a non-rotating connection between two shafts, provided that both shafts are perfectly aligned. However, rigid couplings do not allow for flexibility, movement, or compensation. In this article, you can read about when it is worthwhile to use a rigid shaft coupling, what advantages they offer, and what different types are available.

Cylinder pins / tension pins / offset pins - presentation of DIN and ISO standards according to form

Cylinder pins and tension pins are connecting elements for mechanical components. Standards and norms, such as DIN EN ISO 2338 or ISO 8734 for cylindrical pins or DIN EN ISO 8752 for spring pins, define geometry, tolerances, and application areas. Particularly in mechanical engineering, pinning is a reliable method for connecting components permanently and free of play without having to use screw connections. In this article, we look at different forms of connecting pins and their standardization. We also discuss chamfers and surface finishes. In addition, we present differences in standardization and what you need to consider if you want to use pins with different standards.

Shaft Couplings and Joints - Compensation of Angular and Radial Offset

In drive technology, flexible shaft couplings and shaft joints are essential to transmit torque between two shafts – especially when the shafts are not exactly aligned or when vibrations and sudden load changes occur in the system. This article explains the difference between shaft joints and flexible shaft couplings, what each component can be used for, and what variants there are.
