Screws perform a wide range of functions. While many fasteners are designed to be removable and easy to service, some applications require exactly the opposite. One-way security screws are designed for these situations. Once installed, they cannot be removed without destroying the screw—a deliberate and safety-critical design feature. Why Are One-Way Security Screws So Important? […]

Safety and Load Capacity in Focus In fastening technology, the precise design and specification of screws is critical to the safety and reliability of entire constructions. At Korrodin, we therefore deliberately push screws to their limits. In our breaking torque tests, we determine the maximum torsional load a screw can withstand before it breaks. This […]

The terms steel and stainless steel are often used interchangeably in everyday language, but they describe different groups of materials. As a general rule, stainless steel is a special type of steel. This means that all stainless steel is steel, but not all steel meets the criteria for stainless steel. The Basics of SteelSteel consists […]

Thread-forming screws work on a different principle from conventional bolted joints. Instead of cutting a thread into the material, they form the internal thread themselves as they are driven in. This chip-free process creates a clean, efficient connection—an obvious advantage, especially in high-volume industrial assembly. As the screw is driven in, the material in the […]

When it comes to quality in the automotive industry, the focus is usually on vehicles, components, and production processes. What is often overlooked is the importance of the associated services. That’s exactly where VDA 6.2 comes in. Developed by the German Automotive Industry Association (VDA), the standard is specifically aimed at service providers in the […]

Screws need to securely hold things in place—and sometimes they should blend in with their surroundings or be deliberately incorporated into the design. That’s exactly where RAL coatings come in. RAL is not a product, but a standardized color system with more than 200 clearly defined shades—from Pure White and Flame Red to Anthracite Gray. […]

Screws may look unassuming, but their performance depends on one crucial specification: the property class. It indicates how much tensile force a screw can withstand and at what point it begins to permanently deform. This knowledge is particularly important in mechanical engineering, steel construction, and industrial plant engineering. How Do You Read a Property Class? […]

Welcome back to the world of fastening technology. Today, we’re taking a closer look at how hard fasteners really are—and why this plays a key role in components such as set screws, cylindrical pins, and washers. What Is a Hardness Test? Hardness testing determines how strongly a material resists localized deformation. A defined force is […]

Inspection certificates are often requested after the fact, misunderstood, or underestimated, even though they are a key part of quality assurance and traceability. The EN 10204 standard defines different types of certificates that vary significantly in terms of the information they provide and their intended applications. What Is an Inspection Certificate? An inspection certificate is […]

Standard parts aren’t the right solution for every application. That’s where special drawing parts come in: fasteners manufactured to exact individual requirements and used where standard solutions reach their limits. What Are Drawing Parts? Drawing parts include screws, nuts, pins, and other fasteners that are not manufactured according to DIN, ISO, or other standards. They […]

Gold-plated screws are rare—and for good reason. They are not used where purely mechanical performance is the priority, but whenever reliability, electrical conductivity, and corrosion resistance are essential. Why Are Screws Gold-Plated? Gold has several special material properties: –Excellent corrosion resistance – Gold does not oxidize and remains stable over time –High electrical conductivity – […]

Microencapsulated thread locking uses a pre-applied coating on fastener threads to provide reliable thread locking without the need for additional adhesive. The threads are coated with microscopic capsules containing reactive agents that are barely visible to the naked eye. As the fastener is tightened, the microcapsules break open. The released agent spreads into the thread […]

In the world of fasteners, there is a phenomenon that can go unnoticed for a long time but have serious consequences: hydrogen embrittlement. While it cannot be detected with the naked eye, its effects can appear suddenly and without warning, causing component failure. What Is Hydrogen Embrittlement? During certain manufacturing and surface treatment processes (such […]

Black finishes are mainly used on screws for functional and aesthetic reasons. Depending on the base material, different processes are used, each involving a different chemical process. Black Finishes on Steel: Black Oxide Treatment During black oxide treatment, the surface of steel is deliberately converted in a hot alkaline bath into a thin layer of […]

Zinc plating is one of the most widely used surface treatment processes in fastening technology. It provides basic corrosion protection and helps ensure that fasteners continue to perform their function in the long term, even under demanding environmental conditions. What Is Zinc Plating? Zinc plating involves coating a fastener with a thin layer of zinc. […]

Standards form the foundation of quality, safety and compatibility in industry and technology. They ensure that components, machines, and systems work together seamlessly and operate reliably worldwide. In this context, you often come across the terms ISO, EN, and DIN – but they don’t represent competing sets of standards, but rather different levels of standardization. […]
