Simpson 3-1/2" 16d Annular Ring Shank Common Nail - 316 Stainless Steel, 8 Ga., 10 lb Box (T16HACN10)

The Simpson T16HACN10 is a professional-grade 16d common nail engineered for demanding construction applications where withdrawal resistance and long-term corrosion protection are critical. Manufactured from Type 316 stainless steel, this 3-1/2 inch, 8-gauge annular ring shank nail delivers exceptional holding power and outstanding resistance to corrosion - making it the preferred choice for seaside, coastal, and high-moisture environments. Each 10-pound box contains approximately 440 nails, providing ample supply for large-scale framing, decking, and foundation projects. Made in the United States, the T16HACN10 meets the rigorous demands of modern structural construction.

Key Features

• Annular Ring Shank: The annular ring shank profile dramatically increases withdrawal resistance compared to smooth-shank nails, providing a more secure and lasting attachment in wood framing and structural applications.
• Type 316 Stainless Steel: Offers superior corrosion resistance over Type 304 stainless steel, making it specifically suited for seaside and coastal construction environments where salt air and moisture exposure are constant concerns.
• Full Round Head: The full round head design maximizes surface contact and load-bearing capacity, ensuring a tight, stable connection with minimal risk of pull-through.
• Diamond Point: A precision diamond point tip allows for clean, easy driving with reduced wood splitting, even in dense lumber.
• ANSI/AWC Recommended: Stainless-steel nails are recommended for the construction of permanent wood foundations per the ANSI/AWC Permanent Wood Foundations Design Specifications.
• Made in the United States: Domestically manufactured to consistent quality standards.

Frequently Asked Questions

Why is Type 316 stainless steel recommended over Type 304 for coastal projects?

Type 316 stainless steel offers superior corrosion resistance compared to Type 304 stainless steel, making it specifically suited for seaside and coastal construction environments where salt air and moisture exposure are constant concerns. For projects in high-moisture or marine environments, the T16HACN10's 316 stainless steel composition provides a more reliable, long-lasting hold.

What advantage does the annular ring shank provide over a smooth-shank nail?

The annular ring shank profile dramatically increases withdrawal resistance compared to smooth-shank nails, providing a more secure and lasting attachment in wood framing and structural applications. This makes the T16HACN10 well suited for demanding construction uses where pull-out forces are a concern.

How many nails are included in a 10-pound box of T16HACN10?

Each 10-pound box contains approximately 440 nails, providing ample supply for large-scale framing, decking, and foundation projects.

What are the key specifications of the T16HACN10 nail?

The T16HACN10 is a 3-1/2 inch, 16d common nail made from Type 316 stainless steel with an 8-gauge diameter. It features an annular ring shank for enhanced withdrawal resistance, a full round head for maximum surface contact and load-bearing capacity, and a diamond point tip for clean, easy driving.
