Frequently Asked Questions
- Why is Type 316 stainless steel recommended for siding in coastal or seaside environments?
- Type 316 stainless steel offers superior resistance to corrosion compared to standard steel fasteners, making it ideal for severely corrosive environments including seaside applications where salt air and moisture accelerate the breakdown of lesser materials. These nails are also passivated to further ensure corrosion resistance throughout their service life.
- What advantage does the annular ring shank provide over a smooth-shank nail?
- The annular ring shank increases pull-out resistance and provides greater holding power than a smooth shank. This is especially important in siding applications where wind loads and seasonal wood movement can work fasteners loose over time.
- What is the purpose of the circle pattern head on this siding nail?
- The circle pattern on the full round head serves two practical purposes: it reduces glare on the nail head when exposed to sunlight, and it accepts surface finishes such as paint or stain, helping the fastener blend in with the surrounding siding material.
- How does the blunt diamond point help during installation?
- The blunt diamond point is designed to drive true - meaning it follows a straight path during installation - while also reducing the likelihood of splitting the board. This is particularly beneficial when nailing through wood siding where board integrity is critical to a clean, professional finish.
