DeckWise 8×2-1/2″ Stainless Cedar Screws
DeckWise 8×2-1/2 inch stainless cedar screws are built from 305-grade stainless steel for robust corrosion resistance in outdoor environments. Their trim-head design keeps the screw head slightly recessed, preserving the deck’s surface appearance. The drive is a T20 Torx/Star, paired with Type 17 auger tips to reduce insertion effort and minimize wood splitting. This combination makes them suitable for cedar and similar deck boards where long-term durability matters. The 2-1/2 inch length is ideal for standard cedar decking over typical joist spacing, delivering strong bite without protruding screws.
- Length: 2-1/2 in
- Drive: T20 Torx/Star
- Material: 305-grade stainless steel
- Coating: Exterior-coated for outdoor use
DeckWise 8×1-1/2″ Stainless Cedar Screws
These 1-1/2 inch DeckWise screws are designed for cedar and similar decking assemblies where lighter fasteners are appropriate. They use 305-grade stainless steel for reliable rust resistance and a T15 Star Drive (trim-head) that helps prevent cam-out during tightening. The Type 17 auger tips support quick penetration with minimal splitting, making them a practical choice for mid-thickness cedar boards. The listing notes a generous coverage—roughly 50 square feet of decking per 100 screws—helpful for planning smaller to medium-sized installations.
- Length: 1-1/2 in
- Drive: T15 Star
- Material: 305-grade stainless steel
- Coating: Stainless, outdoor-ready
Deck Plus 1-1/4″ Epoxy Coated Screws
Deck Plus 1-1/4 inch epoxy-coated deck screws feature a self-drilling point, which helps eliminate the need for pilot holes in many cedar and pressure-treated wood scenarios. The coating provides enhanced corrosion resistance, making them well-suited for outdoor cedar decks and other exterior wood projects. They use a Star Drive (Torx) design with six contact points to minimize slipping and cam-out, improving driving accuracy and reducing driver torque. This combination supports reliable installation in damp climates or areas with high humidity.
- Length: 1-1/4 in
- Drive: Torx/Star
- Coating: 4-layer epoxy
- Special feature: Self-drilling point
Jake Sales 10×2-3/4″ Cedar Deck Screws
Jake Sales offers a 10×2-3/4 inch exterior-coated screw set designed for cedar decking and other treated woods. The product is listed as a 1-pound package containing about 85 screws, providing ample quantity for small-to-medium deck projects. It features a Torx/Star drive head for reliable engagement and a coating designed to resist corrosion in outdoor environments. The screws are compatible with AQC lumber applications, making them a flexible option for decks that combine cedar with treated lumber in the frame or substrate.
- Length: 2-3/4 in
- Drive: Torx/Star
- Coating: Exterior coated
- Quantity: ~85 screws per pound
Deck Plus 3″ Epoxy Coated Exterior Screws
Deck Plus 3 inch epoxy-coated exterior screws are designed for robust cedar decking and fence projects. They feature a self-drilling point to simplify installation, a four-layer epoxy coating for enhanced corrosion resistance, and a Torx/Star drive with six contact points to minimize slippage during tightening. This 5 lb box typically includes around 310 screws, offering substantial value for larger installations or ongoing maintenance projects in outdoor environments where corrosion resistance is critical.
- Length: 3 in
- Drive: Torx/Star
- Coating: 4-layer epoxy
- Quantity: ~310 pieces per box
Buying Guide
When selecting cedar decking screws, consider material, coating, drive type, and application details to ensure long-term performance and a clean finish.
Material And Climate Suitability
Stainless steel screws offer superior corrosion resistance in humid or coastal areas, reducing staining and rust over time. Epoxy-coated screws provide strong protection for treated cedar and composite materials, and can be a cost-effective alternative in environments where moisture is a concern. For cedar decks exposed to rain, humidity, or salt spray, both options are viable, but stainless steel generally provides the longest service life in harsh climates.
Coating And Wood Interaction
Coatings protect fasteners from moisture-related degradation. Four-layer epoxy coatings are common on exterior deck screws and help prevent staining of cedar wood while resisting corrosion. When using ACQ-treated wood or composites, ensure the coating is designed to withstand chemicals present in the wood preservative to avoid corrosion or discoloration.
Drive Type And Installation
Torx (Star) drives reduce cam-out and improve driving torque transfer. Common sizes include T15 and T20; some screws use a six-point Star design for enhanced engagement. For cedar, choose a drive that matches your drill bits and driver set, and consider stainless options if you expect heavy moisture exposure. A self-drilling point simplifies installation by eliminating pilot holes on many cedar boards, speeding up projects without compromising hold strength.
Length, Board Thickness, And Joist Engagement
Length should align with deck board thickness and joist framing. For standard cedar boards, 1-1/4″ to 1-1/2″ screws are common for face-fastening and close-to-surface installs, while 2-3/4″ to 3″ screws are typical for fastening through boards into joists or thicker substrates. Longer screws provide deeper engagement but may protrude if boards are already thick, so measure board thickness before purchasing a bulk pack.
Practical Considerations
- Pack size and quantity: larger projects benefit from bulk packs that reduce reordering frequency, while smaller jobs can use mid-size packs for convenience.
- Brand reliability and warranty: choose brands with documented corrosion resistance and favorable reviews for cedar decking.
- Color and staining: epoxy-coated screws often come in brown or bronze tones to blend with wood; stainless options maintain metallic tones but resist weathering longer.
