Because of changing technologies and differing assembly needs, fasteners undergo changes every year. Here are our predictions at Bossard for fastener trends in 2020.
Higher Corrosion Protection
Corrosion, such as rust, can damage metal fasteners and make them disintegrate, which causes the joint to fail. Among the design strategies that can increase corrosion protection is to examine the corrosive environment and define requirements to combat it, such as the ISO 12944 corrosion classes for environments. Avoid geometrical shapes that collect water and dirt that promote corrosion. You can then choose materials that resist corrosion and select an appropriate protection method, such as surface coatings or direct currents.
Controlled Friction Finish
Friction is the force that prevents one surface from sliding over another. Too little friction may loosen fasteners and separate joints. Too much may abrade surfaces and destroy them. Aside from proper design, one way to control the friction on a bolt or screw is to use the best finish. This can include options such as Zinc Flake, Electrodeposited Zinc Nickel, Epoxy Electrocoat, and Hot Dip Galvanization.
Selecting the right finish demands a look at corrosion protection, safety, functionality, the resistance of handling damage, availability, cost, and how critical the joint is to the complete assembly.
Light Weighting Fasteners for Certain Industries
While durability and strength are the primary qualities of a fastener, light-weighting, or weight reduction, is critical in certain industries, such as aviation, automobile manufacturing, or railway transportation. Lighter weights can produce products like cars or airplanes that travel faster and operate more efficiently. Composite materials, such as carbon fiber, can be used in components that are joined through polymer fasteners or with fasteners embedded in the component.
A single-function fastener, such as a screw or bolt, works well in holding together two components. But a fastener that combines several functions can deliver several advantages. It’s more economical because you deal with fewer individual pieces. Assembly becomes faster and safer, which increases productivity and results in shorter throughput time. You gain over 30 percent rationalization potential for the entire value chain for each fastening.
