500 Years of the Free State of the Three Leagues “Graubünden Treasures” – Travelling Exhibition “Graubünden Treasures” – Transportation & Mobility Countersunk Screws

Countersunk Screws

Countersunk screws were used in large quantities in the construction of falsework structures. I’ve given these countersunk screws a place of honour in my home in Wiesen, in remembrance of Richard Coray. The Wiesener Viaduct is also home to me.
