Key Features
304 Stainless Build Type 304 stainless steel helps this roofing fastener hold up in wet, exposed conditions where plain steel nails can become the weak link. Better Roof Deck Grip The annular ring shank increases withdrawal resistance, which matters when fastening roofing materials to OSB or plywood roof decking. Roofing Nailer Ready This Simpson Strong-Tie roofing nail comes in a 15 degree wire coil format for fast loading and fast driving in compatible power roofing nailers.
Overview
The Simpson Strong-Tie S11A125RNB 15° Wire Coil, Full Round Head, Ring-Shank Roofing Nail is a collated roofing nail built for power nailer use in asphalt and synthetic slate roofing applications. This is a collated roofing nail designed for fastening roofing materials to OSB and plywood roof decks. Model Number: S11A125RNB. If you need a corrosion-resistant roofing fastener that feeds in a compatible 15 degree wire-coil roofing nailer and gives you stronger hold than a smooth shank, this is the right type of nail.
This specific version uses Type 304 stainless steel, a 1-1/4 inch length, 11 gauge construction, a 3/8 inch full round head, and a 0.120 inch shank diameter. On the roof, those numbers matter. The full round head gives solid bearing on roofing material, while the diamond point helps the nail start cleanly and drive with less fuss through the shingle and into the deck.
The big story here is the annular ring shank. A ring-shank roofing nail is built to resist pullout better than a smooth-shank alternative, which is exactly what you want when wind, vibration, and seasonal movement put stress on the roof system. Simpson Strong-Tie calls out the increased withdrawal resistance for secure attachment to OSB or plywood roof decks, so this is not just a material upgrade, it is a holding-power upgrade.
The 15 degree wire coil format is about speed and workflow. Instead of hand-driving or constantly reloading loose fasteners, you load a coil into a compatible roofing nailer and keep moving. For roofing crews, repair pros, and builders knocking out repetitive fastening on slope, that translates into less downtime and more consistent installation. If you are matching fasteners to your nailer, Simpson Strong-Tie recommends checking tool compatibility through its Fastener Finder or compatibility matrix.
Material choice is another reason this model stands out. Type 304 stainless steel gives a higher level of corrosion resistance than standard coated steel, making it a smart pick when the roof is going to live outdoors year-round and the fastener itself cannot be the failure point. If you are working in demanding weather conditions and want a stainless roofing fastener instead of settling for a basic coil nail, this model makes sense.
This collated nail is sold in a 7200-piece package, which makes it a practical buy for larger roofing jobs, steady service work, or keeping a crew stocked without running short halfway through the day. The nail is identified as a 3d size and uses a smooth head pattern with a full round head design.
Who should buy it? This roofing fastener is best for roofers, builders, remodelers, and serious property maintenance pros using a compatible 15 degree roofing nailer for asphalt roofing or synthetic slate work. It is also a solid choice for buyers who specifically want stainless steel roofing nails for better long-term corrosion resistance. If you only need a handful of nails for a tiny patch, a full 7200-count coil pack is more than you need. If you are actually doing roofing work with a nailer, this is the kind of bulk pack that keeps the job moving.
