Simpson #10 x 2" Pancake-Head Screw in 410 Stainless Steel is a low-profile, fully threaded fastener engineered for securing clips to wood in standing-seam roofing applications. Designed for professionals who need reliable corrosion resistance in outdoor and weather-exposed environments, this tapping screw features a #2 square drive for positive bit engagement and a Type-A point for clean, efficient penetration into wood substrates. The extra-thin pancake head sits flush and low to keep profiles clean while maintaining strong holding power - making it a dependable choice for roofing contractors and construction crews working with metal roofing systems.

Key Features

• Type 410 stainless steel construction with additional corrosion-protective coating - delivers enhanced resistance to moisture, oxidation, and outdoor exposure, extending fastener service life in roofing environments
• Low-profile pancake head (0.438 in. head diameter) - sits nearly flush with the work surface, reducing interference with overlapping roofing clips and maintaining a clean, professional installation
• #2 square drive - provides superior bit engagement compared to Phillips-style drives, reducing cam-out and improving driving control even in overhead or awkward roofing positions (replacement bit: BIT2S-2)
• Fully threaded shank - maximizes thread engagement along the entire fastener length, pulling materials together tightly and increasing holding strength in wood substrates
• Tapping thread type with Type-A point - self-tapping design cuts its own path into wood, eliminating the need for pre-drilling pilot holes in many applications and speeding up installation
• #10 x 2" size - provides the right balance of diameter and length for securing roofing clips to wood decking without over-penetrating or splitting the substrate

Why This Product

• Purpose-built for standing-seam roofing clip attachment - the low-profile head and tapping thread design work together to secure metal roofing clips to wood framing quickly and cleanly, reducing installation steps and rework
• Corrosion-resistant 410 stainless steel with added protective coating - suited for outdoor roofing applications where fasteners are exposed to moisture, temperature cycles, and environmental wear over time
• Square drive reduces driver slippage on the roof - the #2 square recess holds the bit firmly in place, making one-handed driving easier and safer when working at height or in confined roofing conditions
• Self-tapping Type-A point streamlines the workflow - eliminates extra prep steps by threading directly into wood, helping crews move faster across large roofing projects without sacrificing joint integrity

Frequently Asked Questions

What drive bit does this screw require?

This screw uses a #2 square drive. The compatible replacement bit is the BIT2S-2, which provides a secure, cam-out-resistant fit during driving.

Does this screw require a pre-drilled pilot hole?

No. The Type-A tapping point and tapping thread design allow this screw to cut its own thread path as it is driven into wood, which typically eliminates the need for a pre-drilled pilot hole and helps speed up installation.

Why is a low-profile head important for roofing clip applications?

The low-profile pancake head - measuring 0.438 in. in diameter - minimizes protrusion above the work surface. This is important when securing clips in standing-seam roofing because a lower head profile reduces interference with overlapping components and helps maintain a clean, flush finish.

What makes 410 stainless steel suitable for outdoor roofing use?

Type 410 stainless steel provides meaningful corrosion resistance for outdoor applications, and these screws are also coated for additional protection. This combination helps the fastener hold up against moisture and environmental exposure typical in roofing installations.
