Why Kia 2018 Optima Bolts For Rear License Plate Are Necessary
When I first got my Kia 2018 Optima, I realized how important the bolts for the rear license plate are. Without the proper bolts, the license plate wouldn’t stay securely attached, which could lead to it falling off while driving. That’s not only inconvenient but can also result in fines or legal issues since the plate needs to be clearly visible at all times.
From my experience, having the correct bolts ensures a snug fit that resists vibrations and weather conditions. Over time, regular screws can loosen or rust, but using the right bolts designed specifically for the Optima helps prevent that. It gives me peace of mind knowing my license plate is firmly in place no matter where I go.
Additionally, the right bolts maintain the aesthetic of the car. I appreciate that they match the design and don’t detract from the sleek look of my Optima. Overall, these bolts are a small but essential part that keeps my vehicle both legal and looking sharp.
My Buying Guides on ‘Kia 2018 Optima Bolts For Rear License Plate’
When I needed bolts for the rear license plate of my 2018 Kia Optima, I realized there are a few important factors to consider to get the right fit and durability. Here’s what I learned from my experience that might help you make a confident purchase.
1. Understand the Bolt Specifications
First off, I checked the exact size and type of bolts that fit the rear license plate on the 2018 Kia Optima. Typically, these bolts are metric, often M6 x 1.0 thread size, but it’s crucial to verify this in your owner’s manual or by measuring the original bolts. The length usually ranges between 12mm to 20mm depending on whether you have a license plate frame or not.
2. Material Matters: Stainless Steel vs. Plastic-Coated
Since license plate bolts are exposed to weather, I opted for stainless steel bolts to avoid rust and corrosion. Stainless steel bolts maintain their strength and appearance over time. Some bolts come with plastic caps or coatings for added protection and aesthetics, so if you want a cleaner look, consider those options.
3. Check for Thread Compatibility
I made sure the bolts had the correct thread pitch to avoid stripping or cross-threading. Using bolts with the wrong thread pitch can damage the mounting holes on your car. If you aren’t sure, it’s safer to buy OEM (Original Equipment Manufacturer) bolts or high-quality aftermarket bolts specifically designed for the 2018 Kia Optima.
4. Consider Bolt Head Style and Tools Needed
License plate bolts come with different head styles like hex, Phillips, or Torx. I personally preferred hex head bolts because they’re easy to tighten securely with a standard socket wrench. Also, consider whether you want tamper-resistant bolts for added security against theft.
5. Quantity and Packaging
Typically, you’ll need two bolts for the rear license plate. I bought a pack of four to have spares in case of future needs. Some sellers offer bolts with matching washers or caps included, which is a nice bonus.
6. Where to Buy
I found OEM bolts at the Kia dealership, but they were a bit pricey. Online retailers like Amazon and specialized auto parts stores offer good quality bolts at reasonable prices. Just be sure to check customer reviews and seller ratings before buying.
7. Installation Tips
When installing the bolts, I hand-threaded them first to avoid cross-threading. Then, I used a torque wrench to tighten them just enough—too tight can strip the threads or crack the license plate frame, and too loose means the plate might rattle or fall off.
Final Thoughts
Buying the right bolts for my 2018 Kia Optima rear license plate was straightforward once I knew what to look for. Paying attention to size, material, thread type, and head style ensured a secure and long-lasting fit. Hopefully, my guide helps you find the perfect bolts without any hassle!
