Homesmiths Coach Screw 3/8 X 2"
You should use a Homesmith Coach Screw for making a bond between heavy timber, metal and concrete materials as the screws are made from stainless steel and are quite durable as well. They provide high resistance and won't break so easily. Suitable for outdoor use, the coach screws are moderately weather resistant as well and will last you for a long time. The effectiveness of the screws comes from its externally threaded cylindrical shaft and the sharp pointed tip which can pierce any surface.
