Gearing up for your next project — whether it’s building an entertainment center, shelving for your shop or a larger construction project — requires a bit of pre-planning. You have to think about what materials you’ll need and what fasteners you’ll use. Bolts and screws are two standard options, which brings us to a common question:

When should you use bolts instead of screws?

When it comes to the bolts vs. screws debate, you’ll find they have different advantages because they’re designed for different applications and materials.

Screws are a versatile fastener, which makes them a favorite choice. They provide a secure grip thanks to their threads and they meet the needs of numerous do-it-yourself (DIY) projects. They come in a variety of sizes and types for wood, metal, drywall and even concrete applications.

Screws are designed to be self-tapping, but in many cases you may still want to drill a pilot hole. If you drill all your pilot holes at once, this process is a little less time-consuming, since you limit how often you’re changing out your drill bit.

While you can rely on the DIY “hack” of using a nail to drive your pilot hole, a cordless or corded power drill provides better results. Drills also make the installation — or even removal — of screws easier compared to a handheld screwdriver.

Bolts provide the best holding strength compared to screws and other fasteners. Thanks to their threads, bolts can provide an unparalleled level of holding power. They do require a nut and a washer for their installation. The washer helps to spread the load over a larger surface area, which reduces the wear and tear as well as the loosening of your bolt over time while the nut secures the bolt in place.

Like screws, bolts come in many sizes and types. They’re also usable with several materials ranging from metal and wood to concrete.

FREQUENTLY ASKED QUESTIONS ABOUT BOLTS VERSUS SCREWS

1. WHAT IS THE DIFFERENCE BETWEEN A BOLT AND A SCREW?

Bolts and screws can both provide a secure hold in fastening applications. However, these fasteners are not the same. Usually self-tapping, a screw features a helical groove wrapped around a shaft. The threads of the screw mate with the material it is turned through to hold the screw in place. A Hex Bolt, on the other hand, is not self-tapping and requires a nut to stay secure.

Screws and bolts also differ in shape and cost — screws are often tapered, while bolts are not, and bolts tend to cost more than screws.

2. IS A BOLT STRONGER THAN A SCREW?

Yes, bolts provide greater holding strength than screws. This is partly due to the presence of the Washer, which spreads out the load over a larger surface area. Because bolts offer increased strength, they work well for heavy-duty, load-bearing applications.
