Fasteners materials: how to choose the right one for each application

Selecting the right material for fastening systems is a key factor in ensuring optimal performance, durability, and safety in any context. Each sector has specific requirements, and choosing the correct material means maximizing the efficiency of the component.

At Specialinsert, material selection is an integral part of the design process. Every fastener is developed by carefully evaluating the operating conditions and required characteristics to provide reliable, long-lasting solutions that meet the technical standards of each industrial sector. Thanks to the expertise gained over more than 45 years of activity, the company offers high-performance products, selecting the most suitable materials for every type of application.

Mechanical properties

The mechanical characteristics of the material affect the holding strength, hardness, and ductility of the fastener. Alloy steels, for example, are heat-treated to achieve high tensile strength values, ideal for heavy-duty applications.

Corrosion resistance

In humid or aggressive environments, materials like stainless steel or brass are preferred due to their natural corrosion resistance, ensuring reliability and long service life.

Extreme environmental conditions

Applications subject to temperature changes or magnetic fields require materials capable of maintaining functional integrity. Stainless steel, for instance, remains stable even under strong thermal variations and is non-magnetic.

Specific weight

In sectors where light weight is essential — such as aerospace or automotive — materials like aluminum are preferred as they reduce weight without compromising performance.

Electrical and thermal conductivity

When specific conductive properties are required, materials like brass or aluminum are used, known for their excellent electrical and thermal conductivity.

Identifying the most suitable material improves application compatibility, enhances performance, and extends the life of the assembly.
