#10 x 2-1/2ft Marine Grade Type 316 Stainless Steel Wood Screws - 300

In this review the focus is on a 300-piece pack of #10 x 2-1/2' wood screws made from Type 316 marine grade stainless steel, aimed at builders and homeowners who need corrosion-resistant fasteners for outdoor projects. The single biggest reason to consider these screws is their material: Type 316 marine grade stainless steel which resists rust and ionic corrosion better than common stainless grades, making them a practical choice for decks, docks, and coastal construction where long-term durability matters.

Key Features

• Package Content: 300 screws and a T25 star drive bit are included, providing an ample bulk supply and a matching bit for immediate use.
• Marine Grade Material: Made from Type 316 stainless steel, these screws offer enhanced corrosion resistance for salty or humid environments.
• Versatile Lumber Use: Thread design and length suit hardwood, softwood, and pressure treated lumber, including ACQ, CA, and CCA types used in outdoor construction.
• Efficient Drive System: The T25 star drive (Torx) minimizes cam out and gives secure bit engagement for faster, cleaner installation.
• Sharp Penetration: The Type 17 point helps the screw start easily without predrilling in most decking boards and fence rails.
• Flush Finish: Flat head with nibs leaves a tidy, recessed surface for a professional look once countersunk.

Who It's For

These screws are best for contractors, deck builders, and DIYers working near water or in coastal climates who need reliable corrosion resistance and a bulk quantity for continuous work. The included T25 bit and 300-count package make them convenient for multi-board projects like decks, boardwalks, fences, and jetties.

Those who need extremely high tensile strength in structural connections or who routinely face heavy snap loads should evaluate task requirements carefully, as customer feedback indicates a small failure rate under high-stress conditions. For light interior woodworking or specialty metal fastening, alternative fastener types may be more suitable.

Pros & Cons

Pros

• Excellent corrosion resistance from Type 316 stainless steel for marine and coastal use.
• Large 300-piece pack reduces the need to reorder during a single project.
• T25 Torx drive reduces cam out and speeds installation compared with slotted or Phillips heads.
• Works with a wide range of lumber including pressure treated boards for outdoor construction.

Cons

• Some customers reported a roughly 2% failure rate involving snap resistance under heavy loads.
• Not marketed as a high-tensile structural fastener, so may not be ideal for extreme load-bearing connections.
