⚙️ Key Features

• 0.082 kg
• 28 applications across four engine families
• Supersedes 966360, formerly listed as a hexagon screw
• Quantity varies by assembly, most commonly 8

🔌 Function

Clamps two components together, its integral flange spreading the load across the joint face in place of a separate washer.

⚠️ Common Signs of Failure

• Screw working loose, with the joint face fretting around the head
• Thread picked up, galled or stripped on removal
• Head corroded or its drive rounded so a socket slips
• Thread binding part way down, showing the screw has stretched

🛠️ Service Notes

• Screw 984956 carries the same 0.082 kg listing, so weight will not separate the two. Order by part number, checking the fitment: this one covers four engine families and 984956 is listed for the D range
• The number it replaces was a hexagon screw, so an old joint may have had a separate washer under the head that the flange now takes the place of
