M3X0.5 Ball Plunge Point Set Screw – 45H Steel, Black Oxide Finish
Features a 360° swiveling polished steel ball seated against an internal spring, allowing for smooth engagement and disengagement with minimal surface wear.
The spring-loaded ball provides secure, repeatable indexing or positioning with slight adjustment capability without loosening the screw, making it ideal for panel indexing, fixture alignment, quick-access mechanisms, and other repeatable positioning tasks; length listed refers to the overall length of the set screw.
Material
Precision-machined from 45H steel, heat-treated to achieve high hardness and wear resistance for demanding applications.
Finished with a black oxide coating, providing mild corrosion resistance (meant for dry environments) and reduced light reflection.
The black oxide finish makes these set screws suitable for indoor or controlled environments; for long-term exposure to moisture-rich or corrosive conditions, stainless steel versions are recommended.
Applications
Used in heavy duty fixtures, machinery, tooling setups, industrial equipment, and mechanical assemblies where strength and wear resistance are prioritized.
