A4 Stainless steel part thread wood screws countersunk head and available in extra long lengths up to 300mm long. These are A4 316 marine grade screws suitable for green oak and areas with a salt water environment. They have a torx drive TX25 head that prevents camming out that you may get with pozi drive screws. Another great feature is a double countersunk head that helps with strengthening the screw.
We offer cut point up to a certain length that has ribs under the head to help countersink screws the in to the surface of the wood. It is also recommended that pre drilling is done on very hard woods such as tropical hardwoods.
