Coach Screws


Coach screws from ITA Fasteners are heavy duty screws meant for hardwood applications. They come with a square or hexagonal head and a pointed tip - the entire length of the screw is externally threaded as well. Their applications are in metal-to-metal or metal-to-sheet fastening. Sometimes, they are also used on concrete surfaces for masonry. These screws require a pilot hole into which it has to be inserted. This is done to ensure that the surface material does not split or break.

The pilot hole diameter has to be half the diameter of the screw for soft timbers and three-fourths of the diameter of the screw for hard timbers. The pointed end and external threads ensure that the screws do not slip out of position. Nevertheless, to reduce the impact of the screws on the wood, it is advisable to use a washer. This also makes it easy for the screws to be removed. It is available in stainless steel, carbon steel, and alloy steel to bear more wear and tear while also making it more corrosion resistant.
