RS PRO M3 x 30 mm Hex Socket Countersunk Screw Black, Self-Colour Steel


To keep screws from protruding from equipment or surfaces, use this RS PRO countersunk fastener. It's designed for simple installation using an Allen or hex key to tighten and loosen it. It also has modest dimensions, making it suitable for applications where space is restricted.


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.
