Fastensol Rail Bolt M8 (T-Nut) - Roof Hook & Accessory Fixing for Fastensol Solar Rail

Description

The Fastensol Rail Bolt M8 is a T-nut fixing used to connect roof hooks, mounting brackets, and other hardware to Fastensol mounting rail. It slots directly into the rail channel, giving a secure, adjustable connection point anywhere along the rail's length without needing to feed components in from the rail end.

Beyond roof hooks, the same bolt is commonly used to attach optimisers, microinverters, and other system components directly to the rail, making it a versatile fixing for a wide range of accessory mounting tasks across a Fastensol installation.
