Key Features
Holds solar-field tracker rails to galvanized piers; the thick coating copes with daily thermal cycles from –20 °C to +80 °C.
The unique square-neck design makes Carriage Bolt the first choice for any joint where access is limited to one side and where a smooth, tamper-resistant head is desired. In timber construction the bolt is dropped into a pre-drilled hole; the square neck pulls into the wood when the nut is tightened on the opposite face, eliminating the need for a wrench on the head side.
