The Simpson Strong-Tie N10DHDGPT2500 Strong-Drive 33 Degree SCN Smooth-Shank Connector Nail is a collated connector nail made for installing structural metal connectors in wood construction. This is a collated connector nail designed for structural connector installation in factory-built, modular, and wood-connector fastening applications. Model Number: N10DHDGPT2500. This pack gives you 2,500 hot-dip galvanized nails sized at 10d, 2-1/2 in. long, with a 0.148 in. shank diameter.

What matters here is that this is not just a generic strip nail. Simpson designed this Strong-Drive connector nail for approved connector applications, where the nail dimensions, head style, and coating all need to line up with the hardware and the environment. The smooth shank design helps with fast, easy penetration, which is exactly what you want when you are doing high-volume connector installation and need clean, repeatable driving with a power metal connector nailer.

This version uses a full round head with a smooth head pattern and a hot-dip galvanized finish. In practical terms, the full round head gives the bearing surface expected for connector fastening, while the hot-dip galvanized coating makes this a better fit for exterior applications and preservative-treated wood than bright, uncoated alternatives. Simpson also notes that bright nails are not for exterior or treated-wood use, which is why the coating on this model is more than a box-checking spec. It directly affects where you can use the nail.

The 33-degree collation format is another jobsite-relevant detail. These nails are intended for use with compatible 33-degree paper strip power metal connector nailers, so they are built around fast loading and efficient placement in tight connector locations. If you are installing hangers, ties, and other wood connectors with a pneumatic connector nailer, the angle and collation style matter because they affect fit, feed, and access. This nail is built around that workflow.

Simpson added a couple of smart usability touches that are easy to overlook until you have burned through a few strips on site. The orange-painted tips make it easier to orient the strip quickly during loading, which cuts down on fumbling. The head ID stamp gives you a quick visual check for nail size on the job, which helps when multiple approved fastener types are around the gang box or trailer.

From a spec standpoint, this nail is 9 gauge with a 0.285 in. head diameter and 0.148 in. shank diameter. That combination is what ties the product back to its intended connector applications. The 2-1/2 in. length and 10d size make it suitable for specific Simpson-approved connector installations where that size is called out. As always with connector fastening, the right move is to match the nail to the connector requirement instead of substituting by guesswork.

For buyers, the ideal user is the framing crew, modular builder, or contractor doing repetitive structural connector installation with a compatible 33-degree connector nailer. It is also a good fit for shops and crews that want a large pack count to keep production moving. If you need approved connector nails for wood connectors, want hot-dip galvanized protection, and do enough volume to justify a 2,500-pack, this is the kind of fastener that makes sense.
