One screw for every project, the Inoxalca approach to custom special fasteners

Every industrial project presents different critical issues, often related specifically to the fastening system. Inoxalca’s custom special fasteners are designed to transform the fastening component into an integral part of the assembly’s functionality.

Each component is developed based on a technical analysis carried out jointly with the customer, and aimed at identifying the most effective solution and optimizing industrial costs.

From design to production

Inoxalca manufactures special screws starting from dimensional, functional, and regulatory specifications defined by the customer. The company provides special threads, dedicated head configurations, non-standard lengths, and critical mating configurations, ensuring high repeatability and process stability.

The technologies employed include cold heading, hot forming, and turning. This combination makes it possible to select the most suitable manufacturing cycle according to the required performance and batch size.

Materials and treatments for industrial applications

Inoxalca manufactures custom fasteners in austenitic, ferritic, and martensitic stainless steels, low- and high-strength carbon steels, alloys and superalloys, as well as plastic materials for specific applications.

Dedicated heat and surface treatments are available, designed to improve mechanical strength, fatigue performance, corrosion resistance, and compatibility with aggressive or regulated environments.

To complete its offering, the company supplies assembly kits and special component assembly services, simplifying logistics and production management.

Founded in the 1970s, Inoxalca specializes in standard and special screws and bolts, with solid experience in the production of custom metal parts. The company operates with a quality-oriented approach, providing technical support and flexible supply systems, and is ISO 9001 certified for sectors 17, 29, and 35.
