Welcome to our curated selection of Simpson Strong-Tie screws, where engineering excellence meets everyday construction needs. These fasteners are designed for demanding applications like deck building, heavy timber framing, and subfloor installation, offering unmatched holding power and longevity that pros and DIYers trust for structural integrity.
Why Simpson Strong-Tie Screws Stand Out
Simpson Strong-Tie has built a reputation over decades as a leader in structural solutions, with screws rigorously tested and approved by organizations like ICC-ES. What sets them apart is innovative design: self-tapping points for easy driving, washer heads for flush seating, and specialized coatings like Type 316 stainless steel, E-coat, or double-barrier for corrosion resistance in exterior environments. Whether you're battling coastal humidity or indoor moisture, these screws deliver pull-out resistance far superior to standard options.
Key Features to Consider When Shopping
Selecting the right screw depends on your project demands. Look for:
- Diameter and Length: Options like 0.220-inch diameter in 3- to 5-inch lengths handle thick timbers without splitting.
- Coatings: Interior E-coat for dry applications, exterior double-barrier or black coatings for weather exposure, and stainless steel for marine use.
- Head and Drive: Flat or washer heads with T-25 or #2 square drives prevent cam-out and ensure clean finishes.
- Quantity and Packaging: From small 12-count packs for testing to bulk 2000-count collated strips for high-volume jobs.
- Specialized Designs: Sawtooth points for aggressive bite, ideal for treated lumber.
These features make Simpson Strong-Tie screws versatile across residential and commercial builds. For broader options, explore our Screws category.
Comparing Top Simpson Strong-Tie Models
Our category features standout products tailored to specific needs. The Deck-Drive DWP Wood SS Screw (#10 x 3 in., Type 316) excels in coastal decking with its stainless steel construction, resisting rust in harsh conditions.
For timber framing, the SDWS Timber Screw lineup dominates. Compare the 4-inch x 0.220 versions: the interior E-Coat (SDWS22400-R50) suits protected framing, while exterior double-barrier coated (SDWS22400DB-R50) and black variants (SDWS22400DBB-R50) withstand outdoor elements. The 5-inch black (SDWS22500DBB-R50) tackles deeper penetrations in posts or beams. Bulk buyers love the 250-count SDWS22400DBBMB for efficiency.
Smaller packs like the 12-count SDWS22400DB-RC12 offer trial sizes. For subfloors, the collated WSHL134S7 (#7 x 1-3/4 in.) with phosphate coating speeds installation via pneumatic tools, minimizing squeaks.
Choosing between them? Prioritize length for material thickness, coating for exposure, and quantity for project scale. Timber pros often pair these with Timber Screws alternatives, while deck builders check Deck Screws for comparisons.
Common Use Cases and Applications
These screws shine in high-stakes scenarios:
- Decking and Outdoor Structures: Stainless or exterior-coated models secure joists and railings against weathering.
- Timber Framing: Heavy-duty SDWS models for glulam beams, trusses, and ledger connections.
- Subflooring: Collated WSHL screws for quick, squeak-free plywood-to-joist fastening.
- General Woodworking: Reliable in fences, pergolas, and repairs where strength matters.
Backed by Simpson Strong-Tie's engineering, they reduce callbacks and enhance safety. If your project involves concrete, consider Concrete Screws for hybrid needs, or browse Wood Screws for finer tasks.
