Clear Zinc Cr3 Plated Cup Point Socket Set Screws

Clear Zinc Cr3 Plated Cup Point Socket Set Screws

Clear zinc Cr3 plated cup point socket set screws are precision fasteners engineered for secure, flush installation in high-performance mechanical and industrial assemblies. Designed with an internal hex (Allen) drive and a concave cup-shaped point, these set screws provide strong, vibration-resistant holding power while remaining fully recessed below the surface.

Cup Point Design for Reliable Grip

The cup point is the most commonly used point style for socket set screws due to its superior holding strength. The concave tip bites into the mating surface, creating resistance to both rotational and axial movement. This makes clear zinc Cr3 plated cup point set screws ideal for permanent or semi-permanent fastening in applications where components must remain securely positioned under load or vibration.

Flush, Headless Installation

As headless fasteners, cup point socket set screws sit flush or below the surface of the assembly. This compact design is perfect for space-limited installations and precision equipment where protruding hardware is unacceptable. The internal hex drive allows for easy installation and removal using a hex key, even in tight or recessed locations.

Clear Zinc Cr3 Plating for Corrosion Protection

The clear zinc Cr3 plating provides a durable, corrosion-resistant barrier that protects against rust and oxidation. This trivalent chromium coating is RoHS compliant and environmentally friendly, offering a safer alternative to traditional hexavalent chromium finishes. The bright, clean appearance also enhances the overall look of finished assemblies while extending fastener service life in indoor and light outdoor environments.

Material Strength and Standards Compliance

Manufactured from high-strength alloy steel, these socket set screws are designed to handle demanding mechanical loads. They conform to ASME B18.3 standards, ensuring dimensional accuracy, consistent performance, and reliable compatibility across applications.
