Primary Uses & Applications
- Medical Devices: Assembly of surgical instruments, diagnostic equipment, and implantable device packaging where cleanliness and corrosion resistance are paramount.
- Laboratory & Analytical Equipment: Spacing components in spectrometers, DNA sequencers, and automated fluid handling systems exposed to chemicals.
- Marine & Offshore Electronics: Used in navigation systems, underwater sensors, and communication devices on boats and platforms.
- Food & Beverage Processing: Equipment assembly where cleanability and resistance to corrosive cleaning agents are required.
- Aerospace & Defense: Avionics and critical electronic systems where reliability in harsh conditions is essential.
How to Use
- Clean Environment: For medical and high-purity applications, install in a controlled, clean environment.
- Installation: Use a clean, 3/16 inch hex wrench. Carefully screw the male thread into the receiving tapped hole. The electropolished finish reduces friction.
- Final Assembly: Use a matching #4-40 stainless steel screw to secure the component to the female thread of the standoff.
- Torque Control: For consistent and reliable results, especially in critical applications, use a torque screwdriver set to the recommended value for #4-40 screws in stainless steel.
- Custom Solutions: We can work with you to create standoffs with specific lengths and thread depths to solve unique design challenges in your product.
