M8 Galvanised Cup Head Square Neck Bolt – Heavy-Duty Coach Bolt for Timber and Structural Fixing
The M8 Galvanised Cup Head Square Neck Bolt is a strong, reliable fastener designed for secure timber-to-timber or timber-to-metal connections. Commonly known as a coach bolt, it features a smooth domed head and a square neck beneath that locks into timber to prevent rotation during tightening.
