제품 설명
Heavy Duty Hex Standoff - Male-Female - A4-80 Stainless Steel - Blue-Zinc - for Industrial Use - M3 to M8
Designed for demanding industrial applications, our Heavy-Duty Hex Standoffs provide robust spacing and mounting solutions where strength and reliability are paramount. The H4.75-M3x31+6 size is built to create durable, high-clearance connections in challenging environments. Made from A4-80 (316) Stainless Steel with a protective blue-white zinc plating, they offer superior resistance to corrosion, vibration, and moisture compared to standard A2-70 grade, making them suitable for industrial controls, telecommunications infrastructure, and outdoor applications.

Primary Uses & Applications
- Industrial Automation: Mounting PCBs in PLC cabinets, motor drives, and robotic systems where shock, vibration, and humidity are present.
- Telecommunications Infrastructure: Used in 5G base stations, network switches, and outdoor cabinets requiring mechanical durability and environmental resistance.
- Power Electronics: Spacing and mounting boards in power supplies, inverters, and battery management systems within industrial settings.
- Outdoor & Marine Equipment: Providing corrosion-resistant mounting points in sensor housings, navigation equipment, and control units exposed to the elements.
- Transportation Electronics: Securing control units in automotive, rail, and marine applications (non-safety-critical).
How to Use
- Preparation: Ensure the tapped holes in the base material are clean and free of debris. Using stainless steel screws is recommended for optimal corrosion performance match.
- Installation: Use a correctly sized hex wrench or socket. Screw the male thread into the base material. 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: Place the component over the standoff and secure it with an appropriate stainless steel machine screw. The deep female thread (25mm) allows for a strong connection with various material thicknesses.
- 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.
