⚠️ Common Signs of Failure

• Screw backing off or found missing at service
• Socket rounded by a poor-fitting key
• Thread stretched or stripped on removal
• Corrosion or seizure making the screw hard to shift

🛠️ Service Notes

• This block runs in lengths - 994784 is 12 mm, this one 16 mm and 994782 is 25 mm, so order by the measured length rather than by weight
• 994787 is also published at 0.007 kg but carries no stated length, so mass will not tell the two apart
