6 Best Common Nails For Framing Small Barns Old Farmers Swear By
Framing a barn requires the right nail. We reveal the 6 common nails old farmers trust for superior holding power and time-tested structural durability.
A barn is only as strong as the fasteners holding it together, and a bucket of the wrong nails can undo all your hard work. Choosing the right nail isn’t about fussing over details; it’s about understanding how wood, weather, and time will test your structure. This isn’t just about hammering metal into wood—it’s about building something that will stand for decades.

Why Nail Choice Matters for a Lasting Barn Frame
The difference between a nail that holds and one that fails is often invisible once it’s driven. A nail’s material, coating, and shank design dictate its performance. The wrong choice can lead to rust streaks that weaken the wood, connections that loosen under load, or boards that split wide open during construction. It’s a simple calculation with big consequences.
Think of it this way: a framing nail needs to resist shear forces—the sideways pressure that tries to slide one board past another. A sheathing nail, on the other hand, must fight withdrawal forces—the pulling-out pressure from wind or warping wood. Using a nail designed for one job to do the other is asking for trouble down the line. A strong frame depends on putting the right fastener in the right place, every single time.
Grip-Rite 16D Bright Common: The Standard Workhorse
When someone says "framing nail," this is usually what they mean. The 16-penny (16D) common nail is the backbone of traditional wood framing for a reason. It’s 3.5 inches long with a thick shank and a wide head, providing exceptional strength for joining studs, plates, and rafters. This is your go-to nail for all interior framing components that will be protected from the weather.
The key word here is "bright." A bright finish means the nail is uncoated steel. This makes it affordable and strong, but it also means it will rust quickly when exposed to moisture. Never use bright common nails for sill plates, exterior trim, or any application where they might get wet. They are strictly for the dry, protected skeleton of the barn.
Maze Nails 16D Hot-Dipped for Superior Rust Proofing
For any part of the frame exposed to the elements, you need a galvanized nail. But not all galvanizing is created equal. Hot-dipped galvanized nails are physically dipped in molten zinc, creating a thick, rough, and incredibly durable protective coating. This is the armor your barn frame needs against rain, snow, and humidity.
Use hot-dipped nails for pressure-treated sill plates that sit on concrete, for attaching exterior trim boards, and for building pole barn frames where posts are exposed. They cost more than bright commons, and the lumpy zinc coating can make them slightly harder to drive. But that cost is an investment in preventing rust, which doesn’t just look bad—it expands and can slowly destroy the wood fibers around it.
Pro-Fit 16D Vinyl Coated Sinker for Easier Driving
If you’re hand-driving hundreds of nails, a vinyl-coated sinker will become your best friend. These nails have a thin vinyl coating that heats up from the friction of being driven. This melts the coating, which acts as a lubricant, allowing the nail to slide into the wood with noticeably less effort. It saves your arm and speeds up the work.
The trade-off is in the design. "Sinkers" typically have a slightly thinner shank than a true common nail and a textured, flat head designed to be driven flush without slipping. While they are great for general framing, they have slightly less shear strength than a full-sized common nail. For critical connections like rafters or headers, stick with the beefier common nail.
20D Galvanized Spikes for Securing Posts and Beams
Sometimes a 16D nail just isn’t enough. When you’re connecting heavy timbers—like fastening a 6×6 post to a built-up beam or securing large trusses—you need more length and more girth. A 20-penny (4-inch) or even a 30-penny (4.5-inch) galvanized spike provides the deep penetration and massive shear strength required for these high-stress joints.
These aren’t for framing 2×4 walls; they are for the major structural intersections of your barn. Always use galvanized spikes for these tasks, as posts and beams are often more exposed to moisture wicking up from the ground or blowing in from the sides. Driving these is a workout, but the peace of mind knowing your main frame is locked together is worth the effort.
Grip-Rite 16D Box Nails to Prevent Wood Splitting
Have you ever driven a nail near the end of a board, only to watch the wood split apart? That’s often because the nail’s thick shank acted like a wedge. The solution is a box nail. A 16D box nail has the same length as a 16D common, but its shank is significantly thinner.
This thinner profile displaces less wood, dramatically reducing the chance of splitting. Use box nails when toe-nailing studs or nailing within a couple of inches of a board’s end. The compromise is reduced strength; they bend more easily and have less shear resistance than a common nail. Don’t frame an entire wall with them, but keep a box on hand for those delicate spots.
Pro-Fit 10D Ring Shank for Sheathing That Won’t Budge
Attaching plywood or OSB sheathing is all about withdrawal resistance. Wood expands and contracts with changes in humidity, and wind can create suction forces that try to pull panels right off the frame. A standard smooth-shank nail can work its way out over time, leading to loose, rattling walls.
A ring shank nail is the answer. The tiny rings along the shank act like barbs, gripping the wood fibers and refusing to let go. Once driven, they are almost impossible to pull out. A 10D (3-inch) hot-dipped galvanized ring shank is the perfect fastener for securing wall and roof sheathing. It provides a permanent, unyielding connection that adds immense rigidity to the entire barn structure.
A Note on Hand-Driving vs. Pneumatic Nailers
There’s no shame in using a pneumatic nail gun. It’s fast, efficient, and saves a tremendous amount of wear and tear on your body. For sheathing or production framing, a nailer is almost a necessity for anyone with limited time. However, the collated nails for guns are almost always thinner than their hand-driven counterparts, offering slightly less strength.
Hand-driving gives you a better feel for the connection. You can feel the nail bite into the wood and know when it’s set properly. It forces you to be deliberate and is a skill worth having. For critical structural joints or working with heavy timbers, many old-timers still prefer the control and heft of a good framing hammer and a hand-driven nail. The best approach is often a hybrid: use a nailer for the repetitive work and a hammer for the crucial connections.
Ultimately, the best tool is knowledge. By understanding the specific job each nail is designed for, you can turn a simple box of fasteners into a guarantee of structural integrity. Build it right the first time, and your barn will be there to serve you for years to come.
