ISO 14583 4,8 zinc-plated black half-round head screw with Torx drive

A half-round head screw looks like a standard metal rod with a head at one end that transmits torque and external threads at the other end. The screw head is necessary to use special tools (wrench, screwdriver, pneumatic or electric screwdriver, etc.) to tighten the parts of the structure being assembled.

Applications: Ideal for screw connections in mechanical engineering.

Material: steel.

Coating: black zinc flake. Key characteristics of this coating:

• Organic black topcoat;
• Excellent corrosion protection;
• High coverage on silver and black base coats;
• Attractive, uniform black appearance;
• Very good chemical resistance; enhanced resistance to UV radiation;
• Excellent adhesion—the coating does not peel, crack, or flake off even under mechanical stress or chemical exposure;
• Built-in lubricating component for controlled friction characteristics;
• No hydrogen embrittlement;
• Excellent corrosion resistance in NSST and cyclic corrosion tests.
