Primary Uses & Applications
- Medical Devices: Assembly of surgical instruments, diagnostic equipment, and implantable device packaging where cleanliness and corrosion resistance are paramount.
- Marine Electronics: Navigation systems, underwater sensors, and communication devices on boats and offshore platforms.
- Laboratory & Analytical Equipment: Spacing components in equipment exposed to chemicals and requiring easy decontamination.
- Food & Beverage Processing: Equipment assembly where cleanability and resistance to corrosive cleaning agents are required.
- Chemical Processing: Mounting components in or near equipment exposed to corrosive vapors or splash.
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 A4-80 stainless steel is stronger but can be prone to galling (cold-welding); using a moderate speed and avoiding over-tightening is advised.
- Final Assembly: Use a matching M3 stainless steel screw (max length ~4mm) to secure the component to the female thread of the standoff. Ensure the screw length is chosen to fully engage the female threads without bottoming out.
- Torque Control: For critical applications, use a torque wrench according to the specifications for A4-80 stainless steel to ensure a secure connection without damaging the threads.
- Custom Solutions: We can manufacture standoffs to your exact specifications to solve unique design challenges involving space constraints or specific environmental exposures.
