The Best Subfloor Screws Buying Guide
Knowing the best subfloor screws doesn’t guarantee that you’ll choose the perfect one. Instead, there are certain factors you need to consider before you choose a certain set.
This will help you to understand what kind of screws for subfloor you need. As a result, you’ll find the perfect tools that suit your needs. These factors include;
The size of the holder is something that you should pay close attention to. If the fastener doesn’t have the right size/ length, the entire project will be disregarded. Besides, the finishing and wooden joints will not be strong if you don’t use the right size.
Expert recommends that the screw length should be half the size of the bottom surface. In the case of subfloors, these best size is about 2 to 2.5”. However, some professionals claim 3” fasteners are the best screws for OSB subfloor.
Apart from length, it’s good to consider the gauge and diameter of the screw as well.
2. Head shape
You’ll note that screws have different head shapes. But the most commons head shapes are round head and flat head/ slotted fasteners.
With the flat head shape, you can drive the entire fastener using the diagonal head. The best thing about this type is that you’ll not experience splitting challenges.
On the contrary, a round head/ pan head shape has shallow domes. These types are not common in woodworking projects. However, you can still use them to attach another material on top of wooden surfaces. Either way, the best head shape will depend on your preferences.
3. Drive type
Today, most people use drivers or electric drills to drive fasteners into surfaces. As such, it’s hard to buy a tightening set without considering its drive type. The most common ones include; Phillip screws, square drive, Torx drive, and flatheads
Just like head shape, choosing the best drive type is a matter of personal preferences and needs.
4. Screw tip
The other component you need to consider subflooring screws is their tip. Make sure you choose fasteners with pointed tips. This will promote accurate and effortless drilling by eliminating prior drilling.
Most modern fasteners feature Type-17 Auger points. This tip is very sharp and delivers great performance.
Lastly, make sure you choose tools that are made from sturdy and durable materials. For an indoor project, you can go with fasteners that are crafted from Zinc. But for outdoor projects, consider factors like moisture and weather.
In that case, look for products that are plated or coated to make them rust- and stain-resistant. Today, manufacturers are using high-tech coating methods like Epoxy coat, and HCR. These techniques enable the screws to withstand rust while enhancing their appeal.
