- Notes
- Thumb-turn fastener that holds the front grille on Ford 2000-7000 series and some earlier x01 tractors. Ford's D4NN8N213A is marked no longer available at a New Holland dealer and now points to 83901581, priced at $71.20 on backorder. Aftermarket copies from TISCO and All States sell for about $6 to $9. The part is easy to buy, but the OEM route costs roughly ten times more.

Why it is hard to get
Can this part be made again?
EligiblePhysical replacement
Hand-turned fastener that holds the grille; not structural or safety-related. Best made as a printed head on a captured 5/16-18 steel screw so the thread does not strip. Size not yet measured. Cheap copies exist, so the case rests on the high OEM price.
Candidate materials: PETG, ASA (other fabricator) (confirmed by test-fitting).
EligibleSTL / FreeCAD file
Can be offered as a printable file and an editable FreeCAD model once the measurements are verified.
