6 Types of Screws Every DIYer Needs To Know

Choosing the Right Types of Screws

Screws are designed with their intended materials in mind. Although it’s possible to use a drywall screw with a piece of wood, that doesn’t always mean it’s the best decision. There are multiple reason why choosing the correct screw is important.

• Protection: Screws are designed to protect the materials they’re joining. Using a screw with the appropriate head, length and thread can keep wood from splitting, drywall from drooping and metal from slipping.
• Ease of use: Fastening materials should not be difficult and that’s why the appropriate screw is important. When used with the correct drill, impact driver, wrench or screwdriver, screws should easily penetrate the appropriate materials.
• Secure hold: Because screws are designed with materials in mind, it’s important to select a screw that will hold materials together. A threaded screw secures differently than a partially threaded screw, and a wood screw won’t provide a secure hold in masonry.
• Safety: Using the right screw for the job will ensure materials hold properly and eliminates risks like corrosion of screw material, split wood, faulty joints and other safety concerns.

Some materials are best suited for decorative fasteners, while others can hold up through outdoor construction. “The most common and the worst mistake beginners make is screw material choice,” says Sean Chapman, a carpenter and founder of Tools’n’Goods. “Every professional and DIYer should learn the basic difference between the materials to avoid quick wear-off and rusting.”

• Steel screws are standard for indoor projects, but not for use on decking or outdoor structures.
• Stainless steel screws are similar to standard steel, but provide a rust-resistant alternative that can be used outdoors.
• Hardened steel screws, AKA construction screws, are used in structural builds and can be purchased in coated versions for outdoor use.
• Brass screws are great for door hinges and cup hooks. They’re visually appealing but soft.
