What is a Set Screw M3 Ball?
A Set Screw M3 Ball, also known as a ball lock screw or a threaded ball bearing screw, is a specialized type of screw designed with a precision-machined ball at its tip. This ball is typically made of hardened steel or stainless steel and is used to secure components or assemblies in place by fitting into a mating hole or socket. The "M3" designation refers to the metric thread size, with "M" standing for metric and "3" indicating a 3-millimeter diameter thread. The "PITCH0.5" signifies that the distance between adjacent threads (pitch) is 0.5 millimeters.
The Set Screw M3 Ball is often used in applications where a secure, vibration-resistant connection is required. The ball at the end of the screw provides a point of contact that distributes force evenly, reducing the likelihood of the screw loosening due to vibration or other mechanical forces.

Characteristics of Set Screw M3 Ball
Precision Machining: The ball at the end of the Set Screw M3 Ball is precision-machined to ensure a perfect fit with the mating hole or socket. This precision ensures a secure and reliable connection.
High Strength: The screw is typically made of high-strength materials such as stainless steel (SUS, as indicated in your specifications), which provides excellent corrosion resistance and durability.
Thread Consistency: The M3 thread size with a 0.5-millimeter pitch ensures a consistent and reliable thread engagement, which is crucial for maintaining a secure connection.
Surface Treatment: The DEGREASE surface treatment helps to remove contaminants from the screw's surface, improving its corrosion resistance and ensuring a better fit with mating components.
Salt Spray Resistance: The ability to withstand salt spray testing for over 24 hours (HIGH SALT SPRAY: 24H) indicates the screw's excellent corrosion resistance, making it suitable for use in harsh environments.
Functionality of Set Screw M3 Ball
The Set Screw M3 Ball serves several critical functions:
Securing Components: It is primarily used to secure components or assemblies in place by fitting into a mating hole or socket. The ball at the end of the screw provides a secure and vibration-resistant connection.
Adjusting Tension: In some applications, the Set Screw M3 Ball can be used to adjust the tension or preload on a component. By tightening or loosening the screw, the tension can be finely adjusted to meet specific requirements.
Preventing Movement: The ball at the end of the screw acts as a stop, preventing the component from moving or rotating in unwanted directions.
Distributing Force: The ball distributes the force applied to the screw evenly across the mating surface, reducing stress concentrations and preventing damage to the component.
