Applications of stainless steel fasteners in key sectors in France

Stainless steel fasteners are an essential component in industrial and construction sectors where durability, corrosion resistance and safety are paramount. In France, it is increasingly in demand, especially in environments where environmental or regulatory conditions require high-performance solutions.

Construction and public works (BTP)

France has a particularly dynamic construction sector in regions such as Ile-de-France, Auvergne-Rhône-Alpes and Provence-Alpes-Côte d’Azur. In these urban and coastal areas, stainless steel fasteners are widely used in outdoor structures such as railings, ventilated façades, metal roofs or street furniture. Its resistance to weathering and environmental pollution makes it ideal for environments where maintenance must be minimal, but durability maximum.


Screws used:

  • A2 and A4 stainless steel hexagonal screws and socket screws.
  • Flat washers and grower washers in A2 and A4 stainless steel.
  • Threaded rods in A2 and A4 stainless steel.

Renewable energies (solar and wind)

In regions such as Occitanie, Nouvelle-Aquitaine or Grand Est, the growth of photovoltaic installations and wind farms has boosted the use of stainless steel fasteners, especially in A4 quality, due to its excellent performance against humidity and saline environments. This type of fastener is used in the fastening of metal structures for solar panels, both in fixed installations and with solar trackers. It is also key in mobile joints of orientation systems, where mechanical reliability is required without risk of deterioration due to prolonged exposure to the outdoors.

Screws used:

  • DIN 933 / DIN 931 screws in A4 stainless steel.
    Self-locking nuts and flange nuts in stainless steel A4
    Lock washers and lock washers in stainless steel A4

Agri-food industry

Bretagne, Pays de la Loire and Normandie concentrate a large part of the French food industry. In this environment, A2 stainless fasteners are essential for the assembly of machinery, production lines and structural elements within processing plants. Its ability to withstand aggressive cleaning, chemicals and bacterial growth makes it ideal for meeting the industry’s stringent sanitary regulations. On many occasions, polished or passivated finish fasteners are used to facilitate cleaning and prevent build-up.

Screws used:

  • A2 stainless steel screws with cylindrical or countersunk heads
  • Screws with a polished or passivated finish
  • Safety screws and screws without cavities for more efficient cleaning

Marine and maritime sector

The coastal areas of Brittany, Normandy and the PACA (Provence-Alpes-Côte d’Azur) region are a reference point for port, marine and maritime activity. Here, A4 stainless steel fasteners (type 316) are used for structures and elements permanently exposed to salt water, such as platforms, access ladders, dock installations or moorings. In more technical applications, stainless steel shackles, eyebolts, turnbuckles and cable fittings are used on ships and port auxiliary structures. Their long-term reliability, even in highly corrosive environments, is one of the key factors in their choice.

Screws used:

  • Screws and fittings in A4 stainless steel (resistant to saline environments).
  • Shackles, eyebolts, turnbuckles and snap hooks in A4 stainless steel.
  • Stainless steel cable fasteners for guardrails or protective barriers.

Automotive and railway

Grand Est, Bourgogne-Franche-Comté and Hauts-de-France are historical areas in the development of the automotive and railway sector. In this context, stainless steel fasteners are used in the assembly of systems requiring resistance to vibration, extreme temperatures and aggressive agents. It is used in the fastening of structural components as well as in safety elements or wiring fasteners. Although in some applications carbon steel is preferred for its high strength, stainless steel offers an excellent relationship between durability, low maintenance and operational reliability, especially in outdoor railway infrastructures.

Fasteners used:

  • Stainless fasteners in A2 and A4 stainless steel.
  • Hexagon socket head cap screws, lock washers and self-locking nuts in stainless steel.
  • Stainless steel under-plate solutions for critical fastenings

Stainless steel fasteners are a transversal solution adapted to many strategic sectors in France. Whether for solar energy projects in Occitanie, food installations in Normandie or maritime structures in Brittany, its use guarantees reliability, safety and longevity.
