Coach Screw

Coach Screw from Thomas Potter Ltd

Coach screws are heavy duty screws designed for metal to timber connections, or to join heavy timbers. 

They can also be used with plastic plugs to fasten items into brick or concrete.
 
Coach screws have a square or hexagonal head designed to be used with a spanner.

Coach screws consist of an externally threaded cylindrical shaft that tapers to a point, with a head at the other end. 

When coach screws 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.
