When a reliable threaded connection is required on thin sheet metal components, traditional tapping operations are not always possible or suitable. Threaded inserts provide an effective solution for creating strong and reusable fixing points in materials where the sheet thickness is insufficient to obtain a durable internal thread. They are widely used in industrial assemblies where reliability, ease of installation and long-term performance are essential.
A.T.S. Lamberti supplies a wide range of threaded inserts for sheet metal applications, supporting manufacturers and technical departments in selecting the most suitable solution according to material, thickness, assembly requirements and operating conditions. The range includes cylindrical threaded inserts, hexagonal threaded inserts and semi-hexagonal threaded inserts, available in different configurations to meet specific installation needs.
The external geometry of the insert plays an important role in achieving a secure fixing. Hexagonal and semi-hexagonal threaded inserts are designed to improve resistance against rotation inside the hole, while cylindrical versions offer versatility across many industrial applications. Blind versions are suitable where a closed rear surface is required or where protection from the opposite side of the sheet is necessary.
Threaded inserts are commonly used in sheet metal fabrication, automotive components, electrical equipment, industrial machinery, control panels, enclosures and general engineering applications. They allow manufacturers to introduce reliable threads into thin panels, painted sheets and finished components without requiring complex machining operations, improving assembly flexibility and reducing production constraints.
A.T.S. can supply threaded inserts from M3 to M12 in different materials, including zinc-plated steel, stainless steel 303, stainless steel 316 and aluminium, allowing customers to select the most appropriate option according to mechanical requirements, corrosion resistance and environmental conditions. The correct combination of insert design and material helps ensure a durable and consistent fastening solution.
For installation, A.T.S. also provides threaded insert installation tools designed to achieve accurate and repeatable assembly results. These solutions are particularly suitable for applications where access is limited, such as enclosed sheet metal structures, profiles and tubular components, allowing threaded connections to be created efficiently even in difficult-to-reach areas.
With experience in industrial fastening solutions, A.T.S. Lamberti supports manufacturers, engineers and purchasing teams by providing technical advice and application assistance throughout the selection process. From identifying the most suitable threaded insert for sheet metal to choosing the correct installation method, A.T.S. helps customers improve assembly reliability and production efficiency.
