For most pallet operations, ring shank coil nails deliver enough holding power at a lower cost, but screw shank nails pull ahead when you are using harder or thinner wood species and need maximum withdrawal resistance. The right pick depends on your wood, your nailer, and what your pallets actually go through. Here is the full breakdown.<\/p>\n\n\n\n

How Ring Shank and Screw Shank Coil Nails Actually Differ<\/h2>\n\n\n\n

A ring shank nail gets its name from the concentric rings pressed into the shank during manufacturing. These rings act like barbs. When driven into wood, the wood fibers close back around each ring, creating mechanical resistance against pull-out. The nail grips along its full embedded length.<\/p>\n\n\n\n

A screw shank nail uses a continuous helical thread that spirals from just below the head to the tip. As the nailer drives it, the thread rotates the fastener slightly \u2014 not enough to slow down production, but enough to cut a threaded path into the wood fibers. The result is a fastener that behaves more like a small screw than a smooth nail.<\/p>\n\n\n\n

The practical difference: ring shank nails resist static pull-out well. Screw shank nails resist both static pull-out and vibrational loosening better, which matters when pallets get stacked, strapped, and moved repeatedly over rough terrain.<\/p>\n\n\n\n

Both types are available as coil nails \u2014 collated into circular coils of 200 to 400 nails, held together by wire weld, plastic strips, or paper tape. This collation format feeds high-speed pneumatic nailers used on pallet assembly lines.<\/p>\n\n\n\n

Holding Power: What the Withdrawal Numbers Mean for Pallet Assembly<\/h2>\n\n\n\n

In pallet construction, the nail’s primary job is resisting withdrawal \u2014 the force that pulls the nail straight back out of the wood. Ring shank nails typically offer 40 to 60 percent more withdrawal resistance than smooth shank nails of the same diameter and length. Screw shank nails can push that number higher, sometimes approaching 75 to 100 percent more withdrawal resistance compared to smooth shank, depending on wood density.<\/p>\n\n\n\n

For standard GMA pallets built from mixed southern yellow pine or SPF (spruce-pine-fir), ring shank coil nails are the long-standing default. The wood is soft enough to grip the rings fully, and the withdrawal resistance comfortably exceeds what a typical 2,500- to 3,000-pound pallet load requires.<\/p>\n\n\n\n

Screw shank nails earn their cost premium in three scenarios:<\/p>\n\n\n\n

    \n
  1. Hardwood pallets.<\/strong>\u00a0Oak, maple, and hickory pallets are common for heavy industrial loads. These dense woods resist ring penetration \u2014 a ring shank may not fully seat, reducing actual holding power below the spec-sheet number. Screw shank threads cut through dense grain more reliably.<\/li>\n\n\n\n
  2. Thin wood or engineered deck boards.<\/strong>\u00a0When deck boards are under 5\/8 inch thick, a screw shank’s thread engagement per inch of embedment matters more. Ring shank nails need a certain minimum embedment depth for the rings to do their job. Screw shank can perform with less.<\/li>\n\n\n\n
  3. Export and heat-treated pallets.<\/strong>\u00a0Pallets that ship internationally go through heat treatment (ISPM 15<\/a>), which can slightly alter wood fiber structure. Combined with the vibration of container shipping and multiple forklift moves, screw shank nails reduce the chance of loose joints at the destination.<\/li>\n<\/ol>\n\n\n\n

    If none of those describe your operation, ring shank is probably the smarter buy.<\/p>\n\n\n\n

    Nailer Compatibility: Which Shank Type Fits Your Existing Setup<\/h2>\n\n\n\n

    The good news: shank type alone rarely forces a nailer change. The collation format, nail diameter, and collation angle determine compatibility \u2014 not whether the shank has rings or threads.<\/p>\n\n\n\n

    Most pallet lines run 15-degree coil nailers. These tools accept wire-weld or plastic-collated coil nails from roughly 1-1\/2 inch to 3-1\/2 inch lengths. A 15-degree wire-weld coil of .120-inch ring shank nails loads into the same magazine as a 15-degree wire-weld coil of .120-inch screw shank nails.<\/p>\n\n\n\n
