#10 x 2-1/2ft Marine Grade Type 316 Stainless Steel Wood Screws - 1200

In this review the focus is on a high-count box of fastening hardware aimed at outdoor builders and professional contractors. The 1200 pack of #10 x 2-1/2' stainless steel wood screws delivers one clear selling point: long-term corrosion resistance thanks to Type 316 marine grade stainless steel, which makes these screws a solid choice for decks, boardwalks, fences, and other coastal or wet environments where rust prevention matters most. The package also includes a T25 star drive bit to speed installation, so the kit arrives ready for immediate use.

Key Features

• Package content: The set contains 1200 pieces plus a T25 star drive bit, providing a large, cost-effective supply for medium to large projects without repeated reordering.
• Material quality: Type 316 marine grade stainless steel offers superior corrosion resistance and rust prevention for use in salty or humid conditions.
• Versatile compatibility: These screws are suitable for hardwood, softwood, and pressure treated lumber, including ACQ, CA, and CCA, so they fit a wide range of common construction materials.
• Drive system: The STAR DRIVE (Torx) T25 fitting reduces cam out and allows more torque transfer for faster, cleaner installation with fewer stripped heads.
• Point and head design: The Type 17 sharp point eases penetration into wood and the flat head with nibs leaves a flush surface for a professional finish.

Who It's For

These screws are best for contractors, landscapers, and experienced DIYers who regularly build or repair exterior wood structures, especially near the coast or in wet climates where marine grade corrosion resistance is important. The 1200-count is particularly useful for multi-deck jobs, fence installs, or when stocking a job box for repeated use.

Those doing occasional small indoor projects, or anyone who needs specialized high-tensile fasteners for structural metalwork, should look elsewhere; some customers have reported a small failure rate and occasional issues with tensile snap resistance, so applications demanding the highest tensile strength should consider purpose-made structural screws.

Pros & Cons

Pros

• Excellent corrosion resistance from Type 316 stainless steel ideal for coastal and humid environments.
• Large 1200-piece package reduces trips to buy more fasteners for medium to large projects.
• T25 Torx drive minimizes cam out and speeds installation with a cleaner finish.
• Flat head with nibs and Type 17 point produce flush seating and easier starts in wood.

Cons

• Customers report about a 2% failure rate with some screws showing limited snap resistance under very high torque or shear.
• Not specified as a high-tensile structural fastener, so may not be the first choice where maximum tensile strength is required.

Our Verdict

For exterior woodwork in corrosive or coastal environments these screws are a sensible, value-oriented choice because the Type 316 stainless steel construction and generous 1200-count reduce downtime and replacement need. They are particularly well suited to decking, fencing, and dock board installations, though buyers needing maximum tensile strength for heavy structural loads should evaluate purpose-built structural fasteners instead.

Frequently Asked Questions

Are these screws suitable for pressure treated lumber?
Yes. They are suitable for use with ACQ, CA, and CCA pressure treated lumber thanks to the marine grade stainless construction.

Does the package include an installation bit?
Yes. A T25 star drive bit is included to match the Torx heads and simplify installation.

Are these screws good for coastal and marine use?
Yes. Type 316 stainless steel provides superior corrosion resistance for coastal, marine, and high-humidity environments.
