Key Features
304 Stainless Build Type 304 stainless steel helps this fastener hold up where plain steel nails are a bad choice. That matters when you are framing in damp or corrosion-prone conditions and want longer service life from the connection. Ring-Shank Hold The annular ring shank is built for stronger withdrawal resistance than a smooth shank. In real use, that means a more secure attachment in framing applications where holding power matters. Framing Nailer Ready These Simpson Strong-Tie collated framing nails use a 31° to 34° paper tape format with a clipped head. That setup is made for fast loading and fast repetitive fastening with compatible pneumatic framing nailers.
Overview
The Simpson Strong-Tie S12A237T31 collated framing nails are 2-3/8 in. x 0.113 in. Type 304 stainless steel paper-tape nails built for general framing. This is a collated framing nail designed for pneumatic fastening in wood framing applications. Model Number S12A237T31 gives you an 8d nail in a 31° to 34° paper tape strip with a clipped head, annular ring shank, diamond point, and a 1,000-count package.
What makes this nail worth paying attention to is the combination of stainless material and ring-shank holding power. The annular ring shank is there to increase withdrawal resistance, so the fastener grips better after it is driven. If you are framing and want a more secure attachment than a standard smooth-shank nail can give, this design is the practical upgrade.
The head and collation format matter just as much as the length. This nail uses a smooth clipped head and a 31° to 34° paper tape arrangement, which is the format many framing crews already run in angled pneumatic nailers. That helps with speed on repetitive fastening jobs, but it also means you need to match your nailer to the collation angle and head style before you order.
Material choice is a big part of the story here. The S12A237T31 is made from Type 304 stainless steel, which is a solid choice when corrosion resistance matters more than the lower cost of plain steel fasteners. For builders, remodelers, and contractors working around moisture or in exterior framing conditions where rust can shorten fastener life, that spec is not filler. It is the reason to buy this version.
At 2-3/8 in. long with a 0.113 in. shank diameter and 12 gauge construction, this nail lands in a useful size range for framing tasks that call for an 8d collated nail. The diamond point helps the nail start cleanly, while the smooth head and clipped-head profile support the intended angled-nailer format. The 1,000-count box is sized for real jobsite use, not a one-off repair.
Simpson Strong-Tie lists this fastener under general framing, and that is exactly where it fits best. It is a good match for pros and serious DIY users who already own or use a compatible 31° to 34° paper tape framing nailer and need stainless collated nails with stronger pull-out resistance. If your priority is fast installation, nailer compatibility, and a more secure bite in wood framing, this is the right kind of fastener to look at.
Built for Better Holding Power
The ring-shank profile is the feature that does the real work here. It is designed to resist pull-out better than a smooth shank, which is why these nails make sense when you want a tighter, more secure wood-to-wood connection.
- Annular ring shank for increased withdrawal resistance
- Diamond point helps the nail start and drive into framing lumber
Angled Nailer Format That Loads Fast
This is not a loose nail and it is not a one-size-fits-all strip. The 31° to 34° paper tape format is meant for compatible angled framing nailers, so crews can keep moving through repetitive fastening work without hand-feeding individual nails.
- 31° to 34° paper tape collation
- Smooth clipped head for the specified framing nail format
Stainless Steel Where Corrosion Matters
Type 304 stainless steel is the reason this version stands apart from basic framing nails. When the job calls for corrosion resistance along with collated-nailer speed, this material spec is what justifies the buy.
- Type 304 stainless steel construction
- Suited to general framing where corrosion resistance is important
