NUTS
High Performance Fasteners
Special Nuts for Industrial Applications
Special nuts are essential fastening components designed to ensure secure assembly, mechanical strength and long-term reliability in demanding industrial environments.
Unlike standard components, special nuts can be manufactured according to specific project requirements using customised dimensions, dedicated materials and surface treatments developed to optimise performance.
EFS supplies special nuts manufactured in stainless steels, alloy steels and high-performance materials for critical industrial applications.
REFERENCE STANDARDS
MATERIALS
HEXAGONAL NUTS
Hex nuts for custom bolts
Hex nuts are among the most widely used components in industrial applications to ensure strong and reliable fastening solutions. They can be manufactured in different strength classes and materials, with metric, UNC or custom thread specifications according to customer requirements.
SELF-LOCKING NUTS
Special self-locking nuts
Designed to prevent loosening due to vibration and stress, self-locking nuts feature nylon inserts or metal locking systems that provide a reliable seal even under extreme conditions.
FLANGED NUTS
Custom flange nuts for high-performance fasteners
Flange nuts feature an enlarged bearing surface that distributes the load over a wider area, helping to reduce the risk of loosening. They are particularly suitable for applications requiring high resistance to vibration.
DRAWING NUTS
Custom design nuts for technical hardware
When standard solutions are not suitable, we manufacture custom nuts based on technical drawings, adapting them to specific dimensional and mechanical requirements. Each nut can be produced with custom geometries, special materials and surface treatments to ensure optimal performance.
