These are an organically coated product giving a long lifespan, specifically designed for securing larger section timbers such as railway sleepers. Each screw has a built in cutting flute which eliminates the need to pre-drill holes before using the screw. They have an hexagonal head meaning more torque when screwing them in and each pack comes with a free magnetic driver bit.
