Simpson S10A250CNB 8d x 2-1/2 in. 20 deg. - 22 deg. Collated Ring-Shank Nail 304 SS Full RH 4000-Qty is a professional-grade collated framing nail from Simpson Strong-Tie, engineered for wood framing and wood-to-wood fastening applications that demand reliable holding power in demanding environments. The annular ring-shank design delivers superior withdrawal resistance compared to smooth-shank alternatives, while Type 304 stainless steel construction guards against corrosion where moisture or harsh conditions are a concern. Collated on a 20 deg. - 22 deg. plastic strip, these full round head nails are compatible with many major manufacturers' pneumatic framing tools, reducing driving force and accelerating installation speed on the job site.

Key Features

• Annular ring-shank design - increases withdrawal resistance for a secure, long-lasting attachment in wood framing and structural fastening applications
• Type 304 stainless steel material and finish - provides high-level corrosion resistance, making these nails a dependable choice where moisture or corrosive exposure is a factor
• 20 deg. - 22 deg. plastic-strip collation - compatible with many major manufacturers' pneumatic tools, helping reduce driving force and increase installation speed on the job site
• Full round head with checkered pattern - the checker pattern blends with wood grain, reduces sunlight glare, and accepts surface finishes for a cleaner finished appearance
• Diamond point tip - promotes positive nail placement and smooth, consistent driving through framing lumber
• Painted tip - aids positive placement in the nail gun magazine for efficient, uninterrupted operation
• 10-gauge, 0.131 in. shank diameter at 2-1/2 in. length - delivers the structural shank size required for 8d framing applications without overdriving or splitting
• 4,000 nails per package - high-volume packaging supports extended framing runs and reduces downtime from frequent reloading

Why This Product

• Built-in holding power for structural work - the annular ring-shank shank type mechanically locks into wood fibers, resisting pull-out forces that smooth-shank collated nails cannot match, which is critical in load-bearing framing connections
• Corrosion resistance you can count on - Type 304 stainless steel construction means these nails maintain their structural integrity in moisture-prone or corrosive environments where standard steel fasteners would degrade over time
• Broad pneumatic tool compatibility - the 20 deg. - 22 deg. plastic-strip collation works with many major manufacturers' pneumatic framing nailers, so crews can integrate these nails into existing tool setups without additional equipment
• Backed by Simpson Strong-Tie engineering and domestic production - designed by a trusted name in structural fastening and produced in the United States, these nails are built to consistent quality standards for professional framing applications

Frequently Asked Questions

What makes the annular ring-shank design beneficial for wood framing?

The annular ring-shank increases withdrawal resistance compared to smooth-shank nails, providing a more secure and durable attachment in wood framing applications where holding power is critical.

What grade of stainless steel are these nails, and why does it matter?

These nails are made from Type 304 stainless steel, which provides high-level corrosion resistance. This makes them well suited for applications where exposure to moisture or corrosive environments could compromise the integrity of standard steel fasteners.

Are these nails compatible with pneumatic nail guns?

Yes. The 20 deg. - 22 deg. plastic-strip collation is compatible with many major manufacturers' pneumatic framing tools. Refer to the Tool Compatibility Matrix in the Downloads section below to confirm compatibility with your specific tool model.

How many nails come in a package, and what is the nail's penny size?

Each package contains 4,000 nails. These are 8d penny-size nails measuring 2-1/2 in. in length with a 0.131 in. shank diameter, suitable for standard wood framing work.
