Blaj Fasteners is involved in the development of future hydrogen engines, which require unique technology and capabilities to withstand the demands of the application.

Failures of marine diesel engine components can have serious consequences for a ship, its cargo and the people on board. These consequences can include financial losses, delivery delays or jeopardising the safety of the people on board. This is why it is extremely important to ensure high quality. 

Development of technologies for forming special materials (INCONEL 718, NIMONIC alloy 80A) and dynamically loaded screws for marine, power generation and high-speed train engines.

In shipbuilding and power generation today, it is crucial that engines are efficient, fast and as light as possible and emit as few emissions into the air as possible. To keep pace with our customers in development, we need to develop screws that have the mechanical properties to handle high temperatures and different drive media. Managing the thermal and mechanical effects on the screw is key to ensuring longer service life, safety and performance of the engine. When manufacturing the screw itself, we employ the latest technologies that make the machining process more efficient while increasing quality at the same time.

Blaj bolts are built into steam boilers, steam turbines, water turbines, gas turbines, piston engines, electric generators and pressure equipment by different global manufacturers.

Rapid development allows us to keep up with the ever growing demand in the energy sector. We master the dynamic characteristics of bolts and other fasteners. We guarantee high product quality with controlled production processes in the Blaj factory. Bolts capable of delivering everything you may require from them.

Continuous learning, research and development, combined with the highest production standards at Blaj, guarantee high-quality products delivered within the desired time-frame.

Blaj bolts are integrated in piston engines, steering systems, clutches, propulsion propellers, ship cranes, reducer gears and vibration damping systems. When it comes to safety, when it comes to reliability, when it comes to challenging conditions – we are here for you. Blaj bolts.   

Blaj bolts are built into piston engines, clutches, braking system dampers and braking systems. With Blaj bolts compositions run reliably and safely, since we place responsibility at the centre of our development and production activities. This is our guarantee for product safety throughout the entire production process.  

In each facet of our operation, we focus on the final product to be delivered to the end users by our customers.  The work of our developers and employees in the production department goes beyond the mere production of a bolt – our responsibility extends all the way to the end user of your products. 

Because our company not only manufactures bolts. We are a part of the shared vision created together with you. The machines you are developing, the technology that expands your horizons – we support you in your efforts. With a passion for engineering challenges and with responsibility towards machinery construction.  

Blaj bolts are built into hoisting systems, special metal and plastic processing machinery, construction machinery and fans. Always safe, reliable, further – Blaj.
