⚠️ Common Signs of Failure

• Joint loosening or the component moving
• Flange cracked or bedded into the face
• Shank bent or stretched
• Thread stripped, galled or seized in its hole
• Corrosion pitting along the exposed shank

🛠️ Service Notes

• The old number 21524861 is also replaced by the 60 mm screw 984740, so an order against that number may call for both lengths - check which position each is needed for
• The originals were plain hexagon screws, so do not add a washer under the flange of the replacement
