Cost-reducing Solution for Steel to Wood Connections
The 45° wedge washer with a pre-drill jig is a cost-reducing solution for steel to wood connections. The wedge washer is inserted into a simple, punched or machined hole with an elliptical shape. The minimum required steel plate thickness is reduced to ¼” while maintaining connection capacities. The possibility of reducing the steel plate thickness in combination with simple hole fabrication and fastener installation creates new opportunities for innovative design professionals in timber engineering.
