316 Stainless Steel #4-40 Hex Standoff Screw 12mm Electropolished

Engineered for the most demanding environments, our premium #4-40 Hex Standoff Screws are manufactured from A4/316 stainless steel and feature an electropolished finish. This combination provides exceptional resistance to harsh chemicals, frequent sterilization, salt spray, and corrosive atmospheres.

• 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.

1. Clean Environment: For medical and high-purity applications, install in a controlled, clean environment.
2. Installation: Use a clean, 3/16 inch hex wrench. Carefully screw the male thread into the receiving tapped hole. The electropolished finish reduces friction.
3. Final Assembly: Use a matching #4-40 stainless steel screw to secure the component to the female thread of the standoff.
4. 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.
5. Custom Solutions: We can work with you to create standoffs with specific lengths and thread depths to solve unique design challenges in your product.
