Product Description
Simpson Trim-Head Screw, Type-17 Point, #8 x 2-1/2 in., Quik Guard Coating is a collated decking fastener engineered for attaching wood deck boards to wood substrates with a clean, low-profile result. Its small-diameter trim head with countersinking nibs lets the screw sit flush or below the deck surface, while the Quik Guard coating delivers corrosion resistance suited to exterior and certain preservative-treated wood applications. Curved collation makes these screws purpose-built for use with Simpson Quik Drive auto-feed screw driving systems, supporting fast, consistent installation across large decking projects.
Key Features
- Trim head with nibs for easy countersinking - the small-diameter head seats cleanly below the deck surface, leaving a smooth, professional finish without additional prep work.
- Curved collation - designed specifically for Simpson Quik Drive auto-feed screw driving systems, keeping fasteners feeding smoothly for uninterrupted, high-volume installation.
- Coarse threads - provide strong holding power in wood-to-wood applications, including deck board attachment and fencing.
- #2 undersized square drive - reduces cam-out during driving for better bit engagement and more controlled fastening.
- Type-17 point - bores into wood efficiently, reducing splitting and making it easier to drive screws without pre-drilling.
- Quik Guard coating - provides corrosion resistance for exterior use and certain preservative-treated wood applications, helping fasteners hold up in demanding outdoor conditions.
- Driver bit included in each box - a #2 undersized square-drive bit is included so installation can begin immediately, with replacement bit model BIT2SU available separately.
Why This Product
- Built for auto-feed efficiency - curved collation and compatibility with the Simpson Quik Drive PRO250G2 and PRO300SG2 systems means faster, more consistent screw placement across full deck installations, reducing installer fatigue and improving throughput.
- Clean finish on deck surfaces - the trim head's special small-diameter design, paired with countersinking nibs, eliminates the need for plugs or fillers and leaves deck boards looking finished from day one.
- Exterior-grade corrosion protection - the Quik Guard coating is formulated to resist corrosion in outdoor environments and with certain preservative-treated wood, making these screws a practical choice for exposed deck and fencing applications.
- Ready to drive, right out of the box - each box includes a #2 undersized square-drive bit matched to the screw's drive type, so crews can get started without hunting for compatible tooling.
