When I first bought my 2018 Kia Optima, I quickly realized how important the bolts for the rear license plate are. Without the proper bolts, the license plate can become loose or even fall off while driving, which is not only inconvenient but also against the law. Having the right bolts ensures my plate stays securely attached, giving me peace of mind on the road.
Additionally, using the correct bolts helps prevent damage to the paint and body of my car.

My Buying Guides on Kia 2018 Optima Bolts For Rear License Plate
When I was looking to replace the bolts for the rear license plate on my 2018 Kia Optima, I realized there are a few important things to consider to get the right fit and ensure durability. Here’s what I learned from my experience that might help you too.
1. Understand the Bolt Specifications
First, I checked the exact size and type of bolts needed for the rear license plate. For the 2018 Kia Optima, the standard bolts are usually M6 x 1.0 thread size with a length around 20mm, but it’s always good to double-check your vehicle manual or measure the existing bolts. The bolt head is often a hex or a Phillips head, so you want to pick bolts that match your tools.
2. Choose the Right Material
Since the bolts are exposed to the elements, I opted for stainless steel bolts to prevent rust and corrosion. Stainless steel is durable and keeps the license plate securely attached without worrying about wear over time. Some bolts also come with a coating like zinc plating, which can work well, but stainless steel is my preferred choice for longevity.
3. Consider Anti-Theft Bolts
To add an extra layer of security, I looked into anti-theft license plate bolts. These require a special key to remove, which can help deter theft of the license plate. If security is a concern for you, this is a great option to consider.
4. Look for Bolt Sets That Include Washers
Some bolt sets come with rubber or metal washers which help protect the paint on your car and provide a snug fit. I found it useful to get a set that includes washers so I didn’t have to buy them separately.
5. Check Reviews and Fitment Confirmation
Before purchasing, I always read customer reviews to see if others with a 2018 Kia Optima had success with the bolts. It gave me confidence that the product fit properly and was of good quality. Also, many sellers specify fitment details, so I made sure the bolts were confirmed to fit my model year.
6. Tools Needed for Installation
Installing the bolts is straightforward. I used a standard screwdriver or hex wrench depending on the bolt head type. Having the right tool ensures you don’t strip the bolts or damage the license plate frame during installation.
Summary
To sum up, when buying bolts for your 2018 Kia Optima rear license plate, I recommend confirming the size and thread type, opting for stainless steel or anti-theft bolts if desired, and looking for sets with washers included. Checking reviews and fitment details saved me time and frustration. With these tips, you’ll have your license plate securely and neatly attached in no time!
