| Question | Answer |
|---|---|
| Is this the same as a standard machine screw? | No. A Thread Forming Screw is designed to form its own internal thread in the mating part; a standard screw requires a pre-tapped hole. |
| Which Graco models does 104985 fit? | There is no official single model list published for 104985. It appears in multiple assemblies across different machines. Always verify by checking your specific model’s parts manual or diagram. |
| Can I replace this with a generic screw? | Not recommended. Use the OEM Graco part to ensure proper thread forming characteristics, material hardness, and long-term reliability. |
| Any installation tips? | Start the screw by hand to ensure alignment, then tighten to the recommended torque. Do not over-torque to avoid damaging the formed threads. |
