This handy component is made of stainless steel, a durable material with a high strength-to-weight ratio. A black oxide coating thickens the screw and improves corrosion resistance, making it ideal for use in tough industrial conditions. It can be used for a variety of tasks, including woodworking, DIY constructions and building panels.
