1. Product Overview
This manual provides detailed instructions for the installation and proper use of the ReplacementScrews Stand Screws, specifically designed for the Vizio M551d-A2 television model. This kit ensures a secure attachment of your TV's original factory stand or legs.

Figure 1: Complete set of eight black stand screws. This image displays all eight screws included in the kit, consisting of four short and four long machine screws, all with a black oxide finish.
The kit includes a complete set of eight metric machine screws: four short black machine screws and four long black machine screws. These screws are precisely sized and threaded to be fully compatible with the Vizio M551d-A2 base stand and its pre-threaded metal holes or inserts.
2. Identifying the Screws
Before beginning installation, it is important to distinguish between the two types of screws provided in the kit.

Figure 2: Short and long machine screws. This image clearly shows the difference in length between the four short screws (top row) and the four long screws (bottom row), both designed for specific attachment points on the TV stand.
- Short Black Machine Screws: These are typically used for attaching the stand components to each other or to specific points on the TV where less depth is required.
- Long Black Machine Screws: These are generally used for securing the main stand assembly to the television chassis, requiring a deeper thread engagement.

Figure 3: Close-up of screw heads. This image provides a detailed view of the black oxide plating and the head type of the screws, highlighting their corrosion resistance and matching aesthetic.
All screws feature a black oxide plating, which provides corrosion resistance and a sleek appearance that matches the television's design.
3. Installation (Setup)
Follow these steps to securely attach the original factory stand or legs to your Vizio M551d-A2 television.
- Verify Model Compatibility: Before starting, ensure your television's model number is M551d-A2. This can typically be found on a label on the back of your TV. These screws are specifically designed for this model.
- Position the TV: Carefully place your television face down on a soft, clean, and stable surface to prevent screen damage. Ensure there is enough space to work comfortably.
- Assemble the Stand (if applicable): If your stand requires assembly, use the appropriate short or long screws as indicated by your TV's original stand instructions.
- Attach Stand to TV: Align the stand or legs with the designated mounting holes on the back of the television. Insert the correct screws (typically the longer ones for securing the stand to the TV chassis) into the pre-threaded metal holes.
- Tighten Screws: Using an appropriate screwdriver, carefully tighten each screw until it is snug. Do not overtighten, as this can strip the threads or damage the TV.
- Final Check: Once all screws are tightened, gently lift the TV to ensure the stand is securely attached and stable before placing it in its final viewing position.
Important Note: This screw kit is exclusively designed for attaching the original factory legs or stand to your TV. It is NOT intended for use with universal stands or wall mounting applications, as these typically require different types and sizes of screws.
4. Usage Guidelines
While these screws are primarily for installation, adhering to certain guidelines ensures their longevity and the stability of your television.
- Correct Application: Always use these screws only for their intended purpose: attaching the original Vizio M551d-A2 TV stand.
- Avoid Cross-Threading: When inserting screws, ensure they are aligned correctly with the threaded holes to prevent cross-threading, which can damage both the screw and the TV's mounting point.
- Quality Assurance: These screws are manufactured to high standards to resist stripping and breaking, ensuring a secure and reliable attachment for your TV stand.
5. Care and Storage (Maintenance)
Proper care and storage of any unused screws will maintain their quality and readiness for future use.
- Keep Dry: Store screws in a dry environment to prevent any potential corrosion, despite their black oxide plating.
- Organized Storage: Keep any spare screws in their original packaging or a small, labeled container to prevent loss and ensure easy identification.
- Avoid Harsh Chemicals: Do not expose screws to harsh chemicals or abrasive cleaners, which could damage their finish.
6. Troubleshooting
If you encounter issues during installation, consider the following common problems and solutions:
- Screws Do Not Fit:
- Double-check your TV's model number on the back label to confirm it is M551d-A2. These screws are model-specific.
- Ensure you are using the correct screw length for the specific mounting point. Refer to your TV's original stand instructions if available.
- Verify that you are attempting to attach the original factory stand/legs, not a universal stand or wall mount.
- Screws Feel Loose After Tightening:
- Ensure the screws are fully engaged in the threads. If they feel loose, they might be cross-threaded or the TV's internal threads might be damaged. Do not force them.
- Confirm you are using the correct screws for the specific holes.
If problems persist, contact ReplacementScrews customer support for assistance.
