Best Screws for Fiberglass FAQ

Before you start your project, you should probably have a basic working knowledge of its do’s and don’ts. Additionally, in order to use them safely, you’ll want to learn more about the materials you are using. If you have any questions at all, don’t skip this section–you may find the answers below! Keep reading for some of the most frequently asked questions about finding and using the best screws for fiberglass.

1. What Is Fiberglass?

In order to determine which screws are the best screws for fiberglass, you’ll want to understand exactly what fiberglass is. Fiberglass is reinforced plastic, made up of glass fibers that get embedded in a type of resin. This results in a material that’s stronger than traditional glass and is much more shatter-resistant. Many people use fiberglass for insulation in their homes or around fireplaces because it’s not considered a fire hazard.

2. Why Can’t I Use Regular Screws for Fiberglass?

It’s important to note that screws are not a one-size-fits-all product: there are many different types of screws, in many different sizes, meant for a wide variety of materials. One of the biggest mistakes we see from people working with specific materials like fiberglass is a lack of knowledge–if you use the wrong kind of screw for your project, the results could be disastrous.

Take a look at your local hardware store and you’ll see screws specified for wood, metal, and more. If a screw isn’t meant for fiberglass, only for glass itself, don’t use it.

The reason you don’t want to use screws on the incorrect materials is that it could damage the screw, material, or, in some cases, both. Not only do you risk cracking the material or shattering it, but you could strip the screw itself, making it impossible to use. Choosing the right screws can save you money and a lot of time in the long run.

3. What Features Should I Look for?

When you take a look at all of the products we review below, you may be wondering which features are most important to your project. We always recommend starting with the size and weight of the materials and hold you’re looking to achieve.

If you’re using these screws to hold up a heavy fiberglass panel, look for screws whose packaging mentions durable holds and sharp, gripping threads. After all, they’ll be completely different from screws used in putting together furniture or mounting a photo frame.

Another thing to keep in mind is the final appearance. Will you be painting over your screw heads? If you don’t want to spend the extra money, you may want to opt for materials like stainless steel that look attractive and won’t rust over time.

4. What Additional Tools Do I Need?

If you want to avoid taking multiple trips to the store, interrupting your project, make sure you have all of the tools and supplies you need before you start. Screws and the tools required to use them can easily throw a project off the rails if they’re not chosen properly. Some screws state that, due to their design, they don’t need to be pre-threaded or drilled in order to screw into the wall. Other screws specify that they work best with hand-drills or other power tools.

Keep the tool type in mind, as well as the bit you will need to actually screw the screw in. Some of the screws we’ll review today come with the bit needed; however, many do not. If tools are an issue for you, you can find packs that come with everything included!

5. Does Size Matter?

One of the questions we see all the time is the question of size when it comes to the best screws for fiberglass. If you’re installing something with pre-drilled holes, make sure you use the screw size the instructions specify for the safest and strongest hold. Size really does matter when you’re working with a large or heavy piece.

Do your research, and don’t be afraid to ask your local hardware store employees what they recommend. If you’re shopping on Amazon, you can use their helpful Q&A portion on product pages to connect with actual customers to gain the best insight!

6. Is Fiberglass Strong?

An important aspect to understand about fiberglass is that it’s a strong and sturdy material. You may read the word “glass” and worry about it shattering into pointy shards, but fiberglass is more similar to wood in that it splinters instead.

Due to fiberglass being so strong, you’ll likely need pre-drilled holes for your screws, maybe a fastener of some type. While you can use bits meant for use with wood, we always recommend that you acquire material-specific supplies in order to get the safest and best-looking outcome.

When it comes to shopping for materials for a project, we know how annoying it can be to focus on the minuscule details. No one wants to spend an hour of their time figuring out which screws to use. Instead, you want to focus on the final product, which is why we’ve taken the time to review and find the best possible options for you.

We made our selections based upon a number of strict parameters. These parameters included additional features, any obvious pros or cons, price point (per screw), where you can and how easy it is to purchase the screws, the materials, coatings used, and any available warranties; we synthesized these elements into a single, consise, and coherent review.

You may also notice, especially near the end when we pick our winners, that we heavily took the customer reviews on each product into account. Customer reviews help give us an unbiased insight into each product in order to find the best options for a variety of situations and budgets.

When it comes to the overall price range of the best screws for fiberglass, you’re going to see options anywhere from $10 to $100. The reason you’re going to see such a range in prices is due to packaging size, screw features, and materials. It goes without saying that the higher the quality, the higher the price point, but this is also true for the strength of the hold.

We found that screws that had sharp threads were higher in price than that of smoother ones. Additionally, when screws can promise invisible fasteners and attractive finishes, it makes them that much more expensive: you won’t need to buy extra materials to help conceal your handiwork.
