M10 BZP Round Washers (loose)

M10 x 150mm BZP Hex Head Coach Screws (loose) - are heavy duty screws designed for metal to timber connections, or to join heavy timbers. They have a hexagonal head engineered to be used with a spanner/socket. When they are driven into timber, the threads bite into the wood, while the head stops the screw from going all the way through as it provides compression.
