Hello, we are a trucking company in the US. More than 400 Freightliner trucks under our authority are designed with DD15 oil pans that are fastened using this particular collar screw.
We are looking for the replica or remanufacture of it but with the same quality and dimensions.
Daimler Trucks North America is the original manufacturer in the US.

The part number DDE-A4720140583 refers to a Collar Screw with Decoupling Element, primarily used in Detroit Diesel engines, specifically the DD13 and DD15 models. This component plays a crucial role in securing the oil pan to the engine block, ensuring a proper seal and minimizing vibrations.

Specifications:
Thread Size: M8 X 1.25 mm
Thread Length: 14.72 mm
Overall Length: 63 mm
Design: Flanged external hex head with an integrated decoupling element

We are going to buy 20 pieces just as samples first, test in our trucks and order in huge volume. If you provide good quality and reasonable price, you will become our supplier for the next 10 years. We are opening 4 more new truck shops in the US, now do your calculations.

We are open to do business with factories that have not manufactured this particular screw before but ready to produce using the dimensions, photos, videos and real samples which we can provide.
Trading companies, please do not bother.
We can work only with factories specialized in such screws/fasteners/bolts etc.
