Key Features
Built for Connectors Made specifically for Simpson Strong-Tie connectors, so you get the right nail for hanger, tie, and bracket fastening instead of guessing with generic nails. Hot-Dip Galvanized The Class D hot-dip galvanized coating helps these connector nails hold up better in exterior and treated-wood work where corrosion resistance matters. Right Size, Clear ID This 8d smooth-shank connector nail uses a full round head with size identification, which makes it easier to grab the right fastener on the job.
Overview
The Simpson Strong-Tie N8DHDG-R Strong-Drive SCN Smooth-Shank Connector Nail is a hot-dip galvanized hand-drive connector nail made for use with Simpson Strong-Tie connectors. This is a hand-drive connector nail designed for fastening metal connectors to wood in framing and modular construction. Model Number: N8DHDG-R. If you are installing hangers, ties, and similar hardware, using the nail the connector was designed around matters because load performance depends on the complete connector-and-fastener system, not just the bracket.
For this specific variant, you are getting an 8d nail that measures 1-1/2 inches long with a 0.131 inch shank diameter. That size is commonly used where the connector calls for a shorter nail that still gives proper fit through prepunched holes without overdriving into areas where a longer nail is not required. The smooth shank keeps installation straightforward for hand-drive work, and the full round head gives solid bearing against the connector face.
The coating is one of the big reasons to buy this nail instead of a generic bright nail. Simpson Strong-Tie lists this model as hot-dip galvanized and code-compliant to ASTM A153 Class D, with compliance to ASTM F1667 for metal hardware nails. In plain terms, that means it is built for connector work where corrosion resistance and recognized fastener standards matter. It is also listed as compatible with Simpson Strong-Tie ZMAX connectors, which is important for exterior framing and treated-lumber applications.
Design details are simple, but they matter. The nail uses a smooth head pattern and full round head, plus size identification on the head for easier sorting. On a busy framing job, that saves time because you are not stopping to compare loose nails when several connector fasteners are in the pouch. The 10 gauge body and connector-focused proportions are there for proper fit in hardware, not just general-purpose nailing.
This is not a substitute for every framing nail in the truck, and that is actually the point. A connector nail is a specialized fastener for metal connector installation, not a catch-all nail for random wood fastening. If the connector schedule calls for this style and size, using the matching Simpson Strong-Tie nail helps preserve the intended performance of the assembly. That is especially relevant in structural framing, factory-built or modular construction, and exterior jobs where metal connectors are doing real work.
Compatibility is straightforward: the Simpson Strong-Tie N8DHDG-R Strong-Drive SCN Smooth-Shank Connector Nail is intended for Simpson Strong-Tie connectors and is called out as compatible with ZMAX connectors. Because it is a hand-drive nail, it is best suited to installers working with a hammer rather than collated nailers. That makes it a practical fit for punch-list connector work, small framing crews, repair work, deck reinforcement, and any installation where you need control more than speed.
If you are a framer, deck builder, remodeler, or contractor handling structural connector installation, this is the kind of fastener you buy because the spec actually matters. Serious DIYers working from approved plans also benefit here. The short version: if your Simpson Strong-Tie connector calls for an 8d hot-dip galvanized hand-drive nail, this is the right lane.
Made for Real Connector Work
Connector nails are not the place to improvise. When you are fastening hangers and similar hardware, the right nail size, head style, and coating all matter to how the connection performs.
- Designed for Simpson Strong-Tie connectors
- Hand-drive format gives controlled installation in repair, punch-list, and small framing work
Corrosion Resistance Where It Counts
The hot-dip galvanized Class D coating is the feature that makes this nail a smart choice for exterior connector installation and treated-wood projects. You are buying protection against rust where the fastener sits right against metal hardware.
- Hot-dip galvanized per ASTM A153 Class D
- Compatible with Simpson Strong-Tie ZMAX connectors
Easy to Identify on Site
Small details make the day go smoother. The head identification helps you sort fasteners faster, especially when different connector nails are floating around the pouch or gang box.
- Full round head for solid bearing on connector holes
- Head stamp helps distinguish size during installation
