🔌 Function

Provides a fixed threaded anchor screwed into the casting, so the joint can be clamped and unclamped with a nut without working the casting thread each time.

⚠️ Common Signs of Failure

• Stud pulling out of the casting with the nut
• Thread stretched or necked along the exposed length
• Stud bent or the free end damaged
• Corrosion along the exposed shank locking the nut
• Joint losing clamp load because the stud has stretched

🛠️ Service Notes

• The 225 mm length is what decides this row - the other studs in this group, 994658 at 0.085 kg, 994741 at 0.034 kg and 994776 at 0.027 kg, are quite different fastenings
• A stud that came out with the nut has usually taken casting thread with it; check the tapping before fitting the new one
