A traditional full bodied cut thread countersunk or flat head woodscrew made from fastener grade 97% copper silicon bronze with a square (Robinson) drive - designed to finish flush with the surface of your timber/hardware.
With deep set square socket, our screws have a positive engagement, enabling a rigid alignment of the fastener on the driver, ideal for hard to reach places.
Silicon bronze has a rose gold patina when new or polished. If allowed to age, it will develop a red hued brown tone, akin to Florentine bronze, and is the recommended option for fastening Florentine bronze hardware.
