Screw Connection Arrangement
Simple SummaryContent extracted from patent full text and abstract with AI.
This invention describes a fastening assembly using at least one lightweight metal component and a fastening element, both made from light metal, to connect parts together. The invention specifically proposes a coated surface on the lightweight metal part where the fastening element rests. The coating includes at least one organic lacquer layer with a glass transition temperature of at least 100°C, preferably between 110°C and 125°C, improving durability and performance.
Use CasesContent extracted from patent full text and abstract with AI.
- Automotive or aerospace assembly where lightweight metal parts need to be securely fastened
- Manufacturing of lightweight structures in electronics or machinery
- Appliances or consumer products with components made from light metals such as aluminum or magnesium
- Bicycle, e-mobility, or recreational vehicle production using light alloys
BenefitsContent extracted from patent full text and abstract with AI.
- Improved durability and wear resistance at the interface between metal parts
- Enhanced temperature stability due to the high glass transition temperature of the coating
- Reduced risk of corrosion or damage at fastening points
- Lower weight in assembled products, enabling more efficient and lightweight designs
- Potential for improved production processes with less need for traditional protective washers or inserts
