Fastenere Stainless Steel Deck Screws #8 x 3 - Marine Grade

In this review of the Fastenere Stainless Steel Deck Screws #8 x 3, the bottom line is simple: these are a solid choice for exterior wood and composite projects where corrosion resistance and hold matter most. The reviewer found the 316 marine grade stainless steel and the Type-17 auger point make installation into decking, fence posts, and outdoor trim straightforward while resisting rust in harsh environments. The screws are especially useful for structural deck work and trailer or dock hardware where long-term durability is required.

Key Features

• 316 Marine Grade Stainless Steel: Provides high corrosion resistance for exterior, marine, and coastal projects to minimize rust and staining over time.
• Type-17 Auger Point: The cutting thread tip helps the screw tap into wood and composite decking cleanly, reducing the chance of splitting.
• #2 Robertson Square Drive: The square drive gives good torque transfer making driving and countersinking easier when using compatible bits.
• #8 x 3 in Size: At 3 in length with a 0.340 in head diameter, the screws are sized for structural decking, pole barns, and other heavy-duty wood connections.
• Pilot Drill Recommendations: Clear guidance for a 7/64 in pilot hole for soft wood and 1/8 in for hard wood helps achieve consistent, smooth installation.

Who It's For

These screws are aimed at contractors, deck builders, and experienced DIYers who need durable fasteners for outdoor structures, docks, trailers, and marine-exposed assemblies. The 316 stainless construction and Type-17 point make them well suited to Trex, composite decking, and pressure-treated lumber where corrosion resistance matters.

Those who should look elsewhere are casual hobbyists who need a varied assortment of sizes in one pack or users who require a different drive type; the square drive may not match every cordless driver in a general homeowners toolbox and a different head style may be preferred for finish carpentry.

Pros & Cons

Pros

• Excellent corrosion resistance from 316 stainless for long outdoor life.
• Type-17 auger point makes starting and driving into wood and composite easier.
