Testing of Bolts, Screws & Studs to DIN EN ISO 898-1, ASTM F606-1 & DIN EN ISO 3506-1

Some of the most important fasteners—bolts, screws and studs—are not only considered universally important in industry settings, but also for every day purposes. They are used in construction of complex machinery and equipment as well as vehicles and buildings. Since mechanical stress is concentrated on these types of connection points, the integrity of fasteners is extremely important. Therefore bolts, screws and nuts are subject to strict safety requirements.

Friction Control for Fasteners

The following case studies will explore how two OEMs used different paths and succeeded in reducing non-value added cost. One OEM preferred to use the highest quality materials. This approach resulted in a product that provides extended durability, therefore reducing warranty costs. Another OEM opted to reduce process steps and the associated waste by utilizing the most efficient processes available

Digitalization and Remote Service: Connection for Improving Production

A company’s competitiveness and future viability depend largely on how effectively and quickly it can respond to changing customer needs and markets. These include rising quality requirements, end-to-end traceability along the value-adding chain, delivery reliability, flexibility and cost effectiveness. The technical development of the machines required for production alone is not sufficient to fulfil these complex tasks

Environment-Friendly Zinc Aluminum Flake Coating for Corrosion Protection

Low-carbon steels corrode in most of the atmospheric environments when the relative humidity exceeds 60%. Corrosion is the destruction or deterioration of a material because of reaction with its environment. Most common corrosion control methods use coatings and conversion layers, which contain toxic and environmentally hazardous materials. There is a need to find nontoxic and environmental friendly alternatives compatible with current industrial techniques.

Corrosion-Resistant Coatings for Structural Bolts

High-strength structural bolts are designed for steel-to-steel connections. They are ideal for applications requiring high tensile strength or tension control such as use in bridges, buildings, airports, stadiums and other structures requiring steel-to-steel connections. Structural products are often exposed to many external factors such as water, varying temperatures or salty air, and can corrode quickly if not protected with a coating. Corrosion, which is a process of gradual destruction of metallic materials, can significantly affect the quality of the fasteners. In fact, corrosion is considered one of the leading causes of damage to these fasteners.

Spotlight on Thread Rolling Machinery & Tooling

If I were to rank fastener-making operations in order of importance, thread rolling would come in a close second to forming or heading. As the threads or roll forms produced by thread rolling machines and the corresponding tools like dies and attachments are the defining characteristics of many mechanical fasteners—rivets and pins being a few of the exceptions—the thread rolling process gets a lot of attention and space on the factory floor.
