1. Affordability: Dorman/Autograde cap screws are generally more affordable compared to their OEM (Original Equipment Manufacturer) counterparts.

2. Wide Availability: They are easily accessible through various retailers and automotive parts stores.

3. Interchangeable: These cap screws can be used in place of equivalent OEM fasteners, thanks to their standardized dimensions and materials.

4. Suitable for Class 8.8 Applications: The Dorman/Autograde 875-340 cap screw is suitable for applications that require a Class 8.8 fastener, which is a high-strength bolt with a tensile strength of approximately 120,000 psi (834 MPa).

1. Quality Concerns: There have been reports of inconsistent quality in some batches of these cap screws, which may result in varying thread engagement depths or even stripped threads.

2. Potential for Galvanic Corrosion: The cap screws may be made of different materials (steel alloys) than the components they are being assembled with, potentially leading to galvanic corrosion.

3. Lack of Warranty or Certification: Dorman/Autograde does not offer a warranty on their cap screws, which may be a concern for some users.

The Dorman/Autograde 875-340 cap screw is an affordable and widely available alternative to OEM fasteners, but it comes with some potential drawbacks. These include inconsistent quality, potential for galvanic corrosion, and the lack of a warranty or certification.

If you require high-strength cap screws for applications where safety or reliability is paramount, it is recommended to opt for OEM parts or certified aftermarket alternatives. However, if you are looking for an affordable solution for less critical applications, the Dorman/Autograde 875-340 cap screw may be a suitable choice. Just ensure that you inspect the screws before use and consider the potential risks associated with their use.
