Frequently Asked Questions

Why is 316 stainless steel recommended for roofing applications in coastal or harsh environments?

Type 316 stainless steel offers superior corrosion resistance compared to standard steel or lower-grade stainless alloys, making it especially well-suited for exposure to moisture, salt air, and other harsh exterior conditions. This makes the T10A200X07 a reliable choice for coastal installations where corrosion is a primary concern.

What purpose does the EPDM sealing washer serve on this nail?

The bonded EPDM rubber washer, which is bonded to a stainless steel washer, creates a weather-resistant seal at the fastener point. This helps prevent moisture infiltration where the nail penetrates roofing or exterior sheathing materials, adding an extra layer of protection against water damage.

How does the annular ring shank improve performance compared to a smooth shank nail?

The annular ring shank geometry significantly increases withdrawal resistance compared to smooth shank alternatives. This means the nail resists being pulled back out of the material over time, even under challenging load conditions, providing a more secure and lasting attachment for roofing and exterior sheathing applications.
