Technology and News for the Fastener Industry: Manufacturers, Distributors, OEMs & Users
mensional characteristics and material structure can be 100% controlled with state-of-the-art inspection and sorting machine technology, but there are still defects of aspects that often require a final visual inspection, which only the human eye can guarantee by manual sorting.

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.

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

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

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.

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.

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.

This year, Tesker Manufacturing Corporation, Saukville, WI, USA, celebrates 50 years of thread rolling excellence. Redesign of All Rolling Machines – Tesker has now completed a redesign of all the company’s machines to feature servo-driven, electro-mechanical actuator on the press axis. This feature allows for high-speed actuation and complete push button control over size adjustments, force control and feed rates. Along with a new precision slide system, these features produce a highly rigid and simple to operate machine. Additionally, the elimination of the machine’s hydraulic system saves energy and maintenance as well as reduces noise.

First of all, thank you for your patience and kindness with taking the time to answer all these questions from some Traveling Salesman pestering you from the United States. In 2019, I finally got the opportunity to travel to Ireland and since then it has been of interest to me to interview a distributor. I see from your website you have three locations located in Dublin, Belfast and in Glasgow in Scotland. And when I look at your site I see you distribute several specialty fastener lines. Of course, you also carry show a lot of standard products too. And you have been in business since 1967, so more than 50 years. That is outstanding. Tell us a little bit about Appian. Who owns the company? Share a little history.based in Ireland.

Why Are Platings & Coatings Important? The greatest enemy to fasteners is corrosion. Once corrosion begins, fasteners start to break down quickly, reducing their effectiveness and life span of any application. Fasteners made from carbon or high-strength alloy steels, that are subjected to harsh environments or hazardous chemicals, typically have a plating or coating applied to their surface to protect the steel underneath. Fasteners that lack this protective layer can become damaged, ultimately compromising their assemblies, which can be both dangerous and costly to replace

Fastener Assembly Having a Leak Resistant Threaded Insert
United States Patent 11,009,060, Issued May 18, 2021
Inventor: Dale W. Petty, Wallingford, CT, USA
Assignee: Raytheon Technologies Corporation, Farmington, CT, USA
A fastener assembly may be configured to mount structures in a gas turbine engine. The fastener assembly may comprise a fastener and a leak resistant insert. The leak resistant insert may be configured to at least partially reduce fluid leakage between the coupling of the fastener and the leak resistant insert.
When it comes to fastening plastics there are many different influencing factors at play. The challenge is to find a geometry for the screw fastening that balances out any negative effects such as tolerance fluctuations. Moreover, it is important that the fastening solution is optimally adapted to the material’s properties and the type of load it will need to bearWhen it comes to fastening plastics there are many different influencing factors at play.
