Unifiber M8 Brass Mast Base T-Nut

The Unifiber M8 T-Nut is designed for securing a windsurfing mast base in the board’s mast track. It is a practical replacement part if the original nut is lost or worn and is also worth keeping as a spare when travelling for windsurfing sessions.

Made from brass, it offers good resistance to corrosion in a marine environment. The T-shaped design allows the nut to sit securely inside a standard mast track, while the M8 thread is compatible with mast bases using an M8 mounting bolt.

Key features:

• Application: securing a windsurfing mast base to the board
• M8 thread: designed for mast bases using an M8 mounting bolt
• Material: corrosion-resistant brass
• T-Nut design: suitable for standard windsurfing mast tracks
