Midea 11303125000132 Screw St3.9x12 SUS410 Stainless

Product Description

The MIDEA 11303125000132 is a self-tapping screw used in the assembly and service of Midea home appliances and HVAC equipment. Based on the part designation ST3.9x12, this fastener measures 3.9 millimeters in thread diameter and 12 millimeters in length. It is manufactured from SUS410 stainless steel, a martensitic grade known for corrosion resistance and mechanical strength in indoor and light-exposure environments. This screw is used as an OEM hardware component during manufacturing and in field service repairs. HVAC technicians and appliance service professionals install it when replacing panels, securing components, or restoring factory fastener configurations during unit servicing.

This fastener is suited for residential and light-commercial Midea appliance and HVAC applications where OEM-spec hardware is required. Typical use cases include panel attachment, internal component mounting, and chassis assembly in split-system air conditioners, heat pumps, and other Midea-branded equipment. Using the correct OEM fastener ensures proper thread engagement and prevents damage to plastic or sheet-metal mounting surfaces that are sized for this specific thread pitch and diameter.

Key Features

• SUS410 stainless steel construction for corrosion resistance in appliance environments
• ST3.9x12 self-tapping profile for secure engagement in sheet metal and plastic housings
• OEM Midea part number ensures direct factory-spec replacement
• RoHS-compliant per designation in part reference
• Compact fastener suitable for internal component and panel mounting

Compatibility

Designed as an OEM-style replacement fastener for Midea home appliance and HVAC equipment requiring ST3.9x12 SUS410 hardware. Consult the equipment service manual to confirm fastener specification before installation.

Installation Notes

Installation is typically performed by a qualified appliance or HVAC service technician. Power down and disconnect the unit from its electrical supply before opening any panels or accessing internal components. Use a correctly sized Phillips or square-drive bit to avoid stripping the head. Do not overtighten self-tapping screws into plastic bosses, as this can crack the mounting surface and compromise the assembly.
