Joining

In many industries, from mechanical engineering to tool making and precision mechanics, the precisely tolerated positioning of components determines the quality and longevity of a product. Conventional threaded joints are often insufficient to precisely align and securely join components. This is where reamer bolts come into play – they ensure a play-free guide in bores and ensure repeatable assembly with the highest precision. In this article, you will learn why reamer bolts are the better choice for aligned joints, and the role of tolerances, thread runouts, and undercuts for optimal assembly.

Screw connections can be detached independently or detached without authorization by third parties. In order to prevent this, so-called Safety screws have been developed that make it difficult or impossible to manipulate screws. In addition to safety screws with special screw heads, there are also other design options. In this article you will find everything necessary to protect your screw connection from theft or tampering in the future.

Heavy-duty anchors are a specialized form of metal anchors. Their load capacity is almost unlimited in the interaction of the employed system and the compatible substrate. Heavy-duty anchors with enormous load capacity are used in industrial environments, such as machine construction. The following article provides information on the different types of heavy-duty anchors, their uses and fastening methods.

The tensile strength of steel and stainless steel is a critical parameter when it comes to the load-bearing capacity and safety of threaded joints. It is made up of two key parameters for steel screws based on which the tensile strength and the yield strength can be easily determined. But starting at a certain size, stainless steel screws and stainless steel nuts are marked with a letter-number combination (e.g. A4-80). The letter-number combination arranged in front of the hyphen assigns the screw so marked to a material group and steel group and thus provides information on the basic material properties of the screw. The number 80 to the right of the hyphen indicates the strength class. This article shows how to use the strength class of stainless steel bolts to determine their limits of use and provide an overview of the load-bearing capacity of typical strength classes.

The retaining ring is one of the most important tools in construction. It is used to secure individual components and prevent axial movement. In this article, we will take a look at the different types of retaining rings, their features and their utilization.

Retaining rings are an important component of many machines and systems that serve to secure bearings, shafts, bolts and other components. A commonly used type of retaining rings is type C, which is manufactured according to the Japanese standard JIS. In this article, you will learn more about retaining rings C-type and the Japanese standard JIS.

In this article, we will focus in detail on the subject of pin connections in the mechanical field. We will take a close look at molded parts such as bolts and pins, as well as other fasteners and securing elements and their decisive role in pin connections. We will discuss different examples of pin connections and potential defects when pinning components.

In many industrial and mechanical applications, bearings are critical components that provide low friction, reproducible movement between moving parts, shafts, or axes. Depending on their installation location and function, these bearings must allow different degrees of freedom and be securely fixed. In addition to many other options, locking elements such as retaining rings or slotted nuts or shaft nuts are used to secure machine parts such as rolling bearings, bolts, or shafts against axial displacement.
