And in the midst of this quandary, you might come across another challenge, and that is choosing between 3 1/4 or 3 1/2 framing nails. To help you out, we have prepared this guide so you’ll learn all the key points about these common construction tools.
But before we get started, it’s important that you understand the importance of nails in general. In the construction industry, nails are popular fasteners mainly utilized for structural joining. Power tool specialist Jim Boslice from thejimbosliceworkshop.com says, these are pivotal in installing hardwood floors, roof decking, securing plywood sheathing, and framing projects.
Moreover, there are various types of nails, each with different usage and its own way of application. Therefore, if you’re doing the construction on your own, comprehending the basics is crucial for structural safety and efficiency. The penny system, for one, is a vital term when buying nails in the US.
This sizing system generally uses the traditional English penny abbreviation, which is “d”. So, for instance, a 16-penny nail is known as 16d while a 12-penny nail is 12d. In this guide, we will focus on these two nail sizes and provide an in-depth analysis as well as a blow-by-blow comparison of all their features and costs.
What are 3 ¼ Framing Nails?
In comparison to a 3 ½ inch nail, a 3 ¼ inch nail or 12d is a smaller nail by ¼ inch. But despite their short size, these smaller nails are the best option if you’re using a nail gun. Nail guns are relevant construction machinery that drives the nails mechanically into the surface.
This automatic hammer is useful in building furniture, creating decks, and installing roof materials, among others. When using this tool, you need to take into account the nail size. It’s because the efficiency of the nail gun highly depends on the features of the nail, including the head diameter and shaft thickness.
Therefore, you should make sure that the nail fits the specific length of the nail gun. More than that, choosing the right length is crucial for its efficiency and longevity. And when it comes to nail guns, most contractors would suggest using 3 ¼ inch nails.
These nails are very functional, especially if you’re planning to do some light construction activities or repairs on your own. Since most nail guns use 3 ¼ inch nails, you won’t have a hard time building simple projects where the structural foundation isn’t very crucial.
Although structural integrity is vital in construction, there are creations that aren’t as weighty as residential homes or commercial properties. For instance, if you’re creating pet houses, sheds, pump houses, and the like, 3 ¼ inch nails are recommended.
These nails can also be utilized for interior framing of non-load-bearing walls or walls that only carry their own weight. Thus, if you prefer some DIY constructions using a nail gun, the best nails would be those with smaller size shanks, or simply 3 ¼ inch nails.
And while 3 ¼ inch nails are suitable for nail guns, these can also be maximized for hand driving. You just need to be more focused when hammering the nails because these are smaller in size.
What are 3 ½ Framing Nails?
Now that you understand what a 3 ¼ inch nail is, it’s time to move to the next nail size. A 3 ½ inch nail or 16d nail is often the most recommended size when it comes to framing or fitting together building materials to build a structure and shape.
These particular nail sizes seamlessly connect framing materials such as hardwood and engineered wood, along with drywall, concrete, plastic, and masonry. In general, the 3 ½ inch long nails are the best choice when using a hammer because of their length and durability.
With its size and sturdy features, it is primarily used in creating structural support, from trusses to subfloors. This kind of nail is also effective for wall sheathing, specifically connecting exterior walls and other exterior framing applications.
Aside from these core characteristics, it’s pivotal to know that there are actually two types of 3 ½ inch nails. So, when buying a 3 ½ nail from your local hardware stall, you’ll be asked whether commons or sinkers.
To help you distinguish the two, we will discuss the main difference between these two nail types. Let’s kick off with common nails.
Common nails have bigger diameters with smoother and wider heads. Its diameter generally settles around 0.162 inches, which means it’s quite visible on the surface. More so, this specific nail type supports heavier structural loads.
Because of their sharper point and heavier shaft, the nails can easily get through thicker wood without ruining the fiber that causes the wood to split. These major characteristics make common nails the most appropriate choice for general construction.
Meanwhile, sinker nails are thinner with a flat and smaller head, making them easy to hammer down and slide into the wood smoothly. Compared to common nails, sinkers have a diameter of 0.148-inch and are often layered with vinyl cement or epoxy coating to protect them from unwanted moisture.
More so, sinkers come with textured tips. This specific feature creates a smoother manner of driving the nail into the surface and sliding into the wood. The textured head also provides a better grip when hammering the nail. Thus, sinkers are very manageable when it comes to driving one nail after the other.
