Bolt connections are without a doubt the most used connections within the industry. Achieving the correct pretension is essential in order to guarantee the integrity of the connection. 85%-90% of all bolt connections fails because the wrong pretension was used during installation.
The FC DISC is a new, accurate indicator allowing the application of the correct pretension. The FC DISC has an integrated saucer spring, making the spring’s deflection have a linear effect on the strength.
The FS DISC enlarges the bolt’s elasticity.
The FC DISC can be produced out of several types of material; H13, 17-4 PH, 17-7 PH, Inconel etc. making the FC DISC applicable to every situation.
The FC DISC is available from 1/2″ up to 2.1/2″ and M12 up to M64. In need of a FC DISC with different measurements? Do not hesitate to contact us.
