#8 x 1-5/8 Marine Grade 316 Stainless Steel Deck Screws - Rust

Our review of these #8 x 1-5/8 deck screws finds them best suited for anyone fitting outdoor timber where corrosion resistance matters most. The single biggest reason to buy is the use of Type 316 marine grade stainless steel, which delivers noticeably superior resistance to rust and staining in saltwater or high humidity settings compared with ordinary stainless fasteners. The 1200-piece pack and included T20 star drive bit make it straightforward to tackle a full deck or multiple smaller projects without stopping for supplies.

Key Features

• Package quantity: A 1200-piece bulk pack gives enough screws to cover large deck, fence, or boardwalk jobs without frequent reordering.
• Material: Type 316 marine grade stainless steel construction provides high corrosion resistance suited for coastal and wet environments.
• Drive and bit included: The Torx T20 star drive and supplied bit allow efficient, slip-resistant installation with less cam-out.
• Point and head: Type 17 sharp point and flat head produce easy driving into hardwoods and a flush finish for a neat appearance.
• Versatility: Works with hardwood, softwood, and pressure-treated lumber, making it useful for decks, jetties, fences, and boardwalks.
• Weight and handling: The full pack weighs about 8.23 lb, manageable for transport and storage on job sites.

Who It's For

This pack is aimed at professionals and serious DIYers who need a corrosion-resistant fastener in volume, especially for coastal builds or structures exposed to salt spray. Contractors fitting multiple decks or docks will appreciate the 1200-count and the included T20 bit for quick installation.

Those doing only a handful of interior projects, or who prefer coated fasteners for a specific finish color, might look elsewhere; these screws are optimized for long-term resistance and structural use rather than decorative color-matched heads.

Pros & Cons

Pros

• Excellent corrosion resistance thanks to marine grade 316 stainless steel, reducing risk of rust stains on timber.
• Large 1200-piece quantity offers strong value for multi-job contractors and large DIY projects.
• T20 star drive and included bit speed up installation and reduce cam-out compared with Phillips drives.
• Type 17 point and flat head provide clean countersink and easier driving into hardwoods.

Cons

• Bulk pack weight of about 8.23 lb may be more than needed for small, one-off jobs.
• Only one head finish is supplied, so those needing color-matched heads for visible trim may need alternatives.
