Description
SENCO 08D175W DuraSpin #8 x 1-3/4" Collated Exterior Deck & Dock Screws, #2 Square Flat Head, Type 17 Point, Weatherex® (1,000-Pack)
Speed up high-volume exterior construction with the SENCO 08D175W DuraSpin® #8 x 1-3/4" Collated Exterior Deck & Dock Screws (1,000-Pack). Engineered specifically for professional fence builders, deck installers, and siding contractors, these collated plastic-strip fasteners work with auto-feed screwdriver systems to drive flush into exterior substrates without split boards or dropped fasteners.
Each fastener features a Type 17 slash-cut wood point that chisels through dense wood grain on contact, eliminating pre-drilling and preventing splitting near board edges. The #2 square recess flat head delivers positive bit engagement under high drill RPM, while underhead countersinking ribs leave a smooth, barefoot-safe flush seat. Finished with SENCO’s proprietary Weatherex® multi-layer exterior protective coating, these screws resist corrosion in ACQ and modern preservative-treated lumber, cedar, redwood, marine docks, and exterior siding.
Key Features:
- Weatherex® Multi-Layer Exterior Coating: Protects against rust, staining, and chemical corrosion in ACQ and modern pressure-treated lumber.
- Type 17 Slash Point: Slices wood fibers on contact to prevent edge splitting and reduce driving torque without pre-drilling.
- #2 Square Recess Drive: Provides positive engagement to eliminate bit slippage, stripped heads, and drive cam-out under load.
- 2/3 Coarse Thread Pattern: Draws exterior boards down tight against framing members, preventing board lift and loose fasteners.
- Flat Countersinking Head: Underhead ribs cut cleanly into wood to create a smooth, flush surface finish.
- Jam-Free Plastic Collation: 50-screw flexible plastic strips feed smoothly through auto-feed screwdrivers without binding or misfiring.
- Universal Auto-Feed Tool Compatibility: Runs in SENCO DuraSpin models (DS222-18V, DS225-18V, DS322-18V, DS200) and other compatible plastic-collation systems.

Frequently Asked Questions
What is the difference between the 08D175W (1-3/4") and the 08D200W (2") screws?
The 08D175W is 1-3/4 inches long, making it the preferred fastener length for attaching 5/4" exterior decking boards, fence pickets, and exterior siding where a 2-inch fastener might penetrate through framing or joists. The 08D200W provides a full 2 inches of length for thicker board assemblies and deeper holding bite.
Are these screws safe for use in pressure-treated lumber?
Yes. The SENCO 08D175W features a multi-layer Weatherex® exterior barrier coating tested and approved for use in modern ACQ, copper azole, and micronized copper pressure-treated lumbers without premature corrosion.
Which auto-feed screwdrivers will drive these screws?
These screws fit all standard 2-inch and 3-inch SENCO DuraSpin tools—including the DS222-18V, DS225-18V, and DS322-18V. They are also compatible with most popular plastic-collated auto-feed screwdriver systems on the market.
Does the Type 17 point eliminate the need for pilot holes?
Yes. The Type 17 slash-cut point features a milled chip-relief slot that acts like a drill bit to cut clean paths through wood fibers, preventing edge blowout and board splitting even when working close to the end of a board.
How many screws are included per box?
Each box contains 1,000 collated screws arranged in 20 easy-to-load 50-screw plastic strips, providing enough fasteners to cover approximately 250 to 300 square feet of decking or fencing depending on joist spacing.
