Ethernet Board Connector Cowling Screw (5 Pieces)

About this part

The Ethernet Board Connector Cowling Screw (5 Pieces) (Apple part number 923-12506) is a genuine Apple part that fits the Mac Studio M4 2025. This cowling is the small metal cover that clamps the Screw (5 Pieces) connector to the logic board. Its job is to keep that connector seated and shielded inside the case. If it is missing or bent, the connector can lift slightly and the connected component can become unreliable.

Before you order, match the model identifier on your Mac (Apple menu, About This Mac, System Report) to the identifier listed for this part: Mac16,9.

Signs the cowling needs replacing

• The cowling went missing after a previous repair
• A bent cowling that no longer sits flat
• A connector underneath that keeps working loose
• A component that cuts out after the bottom case was opened
