Different Screw Head Types
When you picture a screw, you might imagine a Phillips head or a slotted screw. Those are two common screw drive types, but there are so many other different screw drives in the world — and each offers its own unique value and benefits. Here’s a look at different types of screw drives for you to consider as you search for the perfect fastener head type to complete your work quickly and effectively:
- Slotted: Slotted drive screws are perhaps the simplest you’ll find. These types of screws are driven using flat head screwdrivers or drills with flat head bits. The challenge with slotted screws — common though they might be — is that it can sometimes be difficult to stabilize the screw during installation. That is, it’s easy for your screwdriver or drill to slip when driving a slotted screw. For that reason, slotted screws are still commonly used — but they’re generally on the decline. This is especially true for contractors and others who need to drive many screws as quickly as possible.
- Phillips: What is the best type of screw head? Many would say the Phillips head screw, which is commonly used and a lot more stable than a slotted screw. Most anyone has a Phillips-head screwdriver sitting around they can use to drive Phillips screws, and the sizing of Phillips drill bits and screwdrivers is relatively simple and straightforward. You’ll come across #1, #2 and #3 Phillips heads, though #2 is the most common size.
- Phillips Tamper-Resistant: A Phillips tamper-resistant screw is just like a Phillips drive screw with one big exception. It includes a small pin in the center of the screw head that prevents — you guessed it — tampering. Phillips tamper-resistant screw heads are a little more obscure because you have to have the right tools to install and remove them. Also, tamper-resistant screws aren’t nearly as strong as regular Phillips head screws, and they are difficult to use in high-torque applications
- Square Recess: Square recess screw heads are becoming more and more popular for a good reason — tools used to drive them very rarely slip out of place. If you’re interested in working as quickly as possible, square recess screw heads might be your best bet. They come in two standard sizes: #2 and #3.
- Square Recess Tamper-Resistant: This is just like the tamper-resistant Phillips head screws in that they are similar to regular square recess screws head with one key addition — a small pin in the center that prevents tampering.
- Quadrex: Quadrex screw heads are a unique amalgamation of Phillips heads and square recess heads. They are relatively rare, though they do provide a great deal of stability, allowing those using them to work quickly.
- Pozidriv: It’s rare to find Pozidriv screw heads in the United States, as they are much more commonly used in Europe. These types of screw heads are a lot like Phillips heads, though they have four additional contact points that provide greater stabilization.
- Torx: Torx screw heads are also gaining in popularity. This is an entirely new design that’s often used in the construction and manufacturing of electronic products.
- Torx Plus: Torx plus screws are much like Torx screws, but their design creates a larger contact area between the screw head and the tool being used to drive it. This produces greater torque and greater ease in driving the screw.
- Torx Tamper-Resistant: This means you get a Torx-style screw that includes the small pin to prevent tampering.
- Torx Plus Tamper Resistant: With a Torx plus tamper-resistant, you get the greater contact area for greater torque, plus the small pin in the center of the head that prevents tampering.
- Tri-Wing: Tri-Wing screw types are somewhere between a slotted and Phillips head. They have three grooves that are slightly curved and come in #1, #2 and #3 sizes, though this screw head type is exceedingly rare.
- Spanner: Spanner screws features two holes or two slots that are used to look into a screwdriver or drill bit for installation.
