6 Best Screw Shank Nails for Fencing
For a fence that can withstand stubborn goats, farmers trust screw shank nails. Their threaded design provides superior holding power for lasting security.
I’ve seen a determined goat treat a brand-new fence line like a personal scratching post, a jungle gym, and an escape puzzle all in one afternoon. If you’re raising goats, you know that a fence is less a simple barrier and more a daily test of engineering. The single most common point of failure isn’t the post or the wire; it’s the humble nail that holds it all together.

Why Screw Shanks Are Essential for Goat Fencing
A standard smooth shank nail relies purely on friction to stay in a wood post. Over time, as wood expands and contracts with moisture and temperature changes, that friction lessens. A goat leaning, rubbing, or pushing on the fence will work that smooth nail right out. It’s a slow-motion escape plan.
A screw shank nail, also called a spiral shank, changes the game entirely. Its threaded design forces it to turn like a screw as it’s driven in, cutting its own threads into the wood fibers. This creates a mechanical lock, not just a friction hold. To pull out, the nail has to tear through wood, which requires significantly more force than a goat can typically generate. This design is your first and best defense against fence loosening.
Maze Nails P.T.L. for Maximum Holding Power
When you need absolute certainty that a nail will not back out, Maze Nails are the standard. Their P.T.L. (Post and Truss Lok) nails are specifically designed for treated lumber, which is what most of us use for fence posts. The threads are aggressive and the nails are double hot-dipped galvanized, providing a thick, durable zinc coating that prevents rust for decades.
This isn’t your cheapest option, but think of it as an investment. You use these on critical points—gate posts, corner braces, and anywhere you’re attaching high-tensile wire. The peace of mind from knowing your anchor points are rock-solid is worth the extra cost, especially when you consider the time and labor saved on future repairs.
Grip-Rite Hot-Dipped Nails for All-Weather Use
Grip-Rite is the workhorse nail you can find at nearly any hardware or farm supply store. Their hot-dipped galvanized screw shank nails offer a fantastic balance of performance, availability, and cost. The hot-dipping process creates a much thicker and more resilient anti-corrosion layer than cheaper electro-galvanized coatings, making them suitable for years of exposure to rain, snow, and sun.
This is a great all-around choice for attaching woven wire or fence boards along the main stretches of your fence line. While maybe not as tenacious as a premium Maze nail, their holding power is more than adequate for the job. For a reliable, everyday fence, Grip-Rite delivers consistent quality without breaking the bank.
Simpson Strong-Tie Nails for High-Stress Corners
Your fence is only as strong as its corners and brace assemblies. These are the points that bear the full tension of the entire fence line. This is where you need a nail engineered for structural loads, and that’s exactly what Simpson Strong-Tie specializes in.
While often associated with building construction, their hot-dipped galvanized structural connector nails are perfect for fencing. They are manufactured to tight tolerances and designed to resist shear forces—the sideways pressure that a taut fence wire exerts. Using these to build your H-braces ensures that your corners won’t sag, shift, or pull apart under strain.
Pro-Fit Bulk Box: The Economical Fencing Choice
Let’s be realistic: fencing a large pasture requires a lot of nails. When you’re looking at hundreds or thousands of attachment points, the cost per nail really starts to matter. Pro-Fit and other similar bulk-box brands offer a practical solution for long stretches of fencing where the primary goal is simply to hold the wire in place.
The tradeoff is sometimes a less consistent galvanization or a slightly less aggressive thread pattern. However, for attaching field fence to line posts, they get the job done effectively. The key is to use them for the right application—the long, straight runs—while saving your premium nails for the high-stress corners and gates.
Hillman Spiral Shank Nails for Dense Wood Posts
Not all fence posts are created equal. If you’re using dense hardwoods like osage orange, black locust, or seasoned oak, you need a nail that can penetrate without splitting the wood. Hillman’s spiral shank nails are sharp, strong, and well-made, allowing them to drive into tough wood more easily.
A lesser nail might bend or, worse, cause a split in your expensive, long-lasting post, compromising its integrity from day one. The holding power of a spiral shank in dense hardwood is phenomenal. It creates a bond that is almost impossible to break without destroying the wood itself.
Tree Island Stainless Steel for Coastal Farms
If you farm anywhere near the coast, you know the destructive power of salt air. Standard galvanization, even a thick hot-dipped coating, will eventually succumb to the corrosive environment. For these situations, stainless steel is not a luxury; it’s a necessity for a long-lasting fence.
Tree Island is one of several reputable brands offering stainless steel screw shank nails. The upfront cost is significantly higher, there’s no way around that. But a galvanized nail might rust through in just a few years, causing your fence to fail, while a stainless steel nail will last for the life of the wood post. It’s a classic "buy it once, cry once" scenario.
Proper Nailing Technique for Maximum Security
The best nail in the world won’t work if it’s installed improperly. Never drive the nail perfectly perpendicular to the grain and flush with the wire. This creates a hinge point and traps moisture, accelerating rust and wood rot.
Instead, follow two simple rules for maximum security. First, drive the nail at a slight downward angle. This uses gravity to your advantage and increases pull-out resistance. Second, leave the nail head proud by about 1/8 of an inch. This allows the fence wire to move slightly with temperature changes and wildlife pressure without working the nail loose. It’s a small detail that makes a huge difference in the longevity and strength of your goat fence.
Ultimately, your choice of nail comes down to your specific conditions—your wood, your climate, and your budget. But choosing a screw shank design is non-negotiable for keeping goats contained. A fence is a system, and paying attention to this small but critical component ensures the entire system works, keeping your animals safe and your garden un-eaten.
