The Pinnacle range of Couplers are designed to help extend the lengths of your fasteners. They can be installed on threaded objects including hex screws. Our Hex Couplers are often used for balustrading and structural applications.



Hex Couplers can be one of the most resilient and useful fastening solutions in your toolkit. Also referred to as coupling nuts, these are designed to connect two pieces of male threaded objects together. A perfect example of this is a pair of hex screws. When you connect two hex screws or bolts together you can make an extra-long stud.

The Pinnacle range of Couplers mainly come in a hex bolt shape. Constructed from steel, these Couplers come in a wide range of sizes and finishes including galvanised. Our Couplers range is available at your nearest Bunnings Warehouse.
