🔌 Function

Clamps a substantial joint together, the integral flange spreading the head load across the component face.

⚠️ Common Signs of Failure

• The joint it clamps working, knocking or moving
• Flange dished or the head seat pulled into the face
• Thread necked or stretched under the head
• Screw seized in its hole and shearing on removal
• Rust weeping from around the head

🛠️ Service Notes

• Hexagon screw 994491 is published at 0.225 kg, only 2 grams apart, so the two cannot be told apart by weight - the head form and the part number are the guide
• Check the tapped hole and the mating faces before refitting a fastener of this size
