Key Features
305 Stainless Build Type 305 stainless steel gives this screw the corrosion resistance needed for exterior wood projects where standard interior fasteners do not belong. Lower Driving Torque The raised-ridge box thread design helps reduce driving torque, so the screw goes in easier, especially in tougher deck board material. Collated for Speed This collated wood screw is built for Quik Drive fastening, which helps speed up repetitive deck fastening and keeps installation moving on larger jobs.
Overview
The Simpson Strong-Tie SSDWP3S305 Deck-Drive DWP Wood SS Screw is a collated exterior wood screw built for wood-to-wood fastening in decks, docks, boardwalks, fascia, trim, and other outdoor assemblies. This is a collated wood screw designed for fastening wood to wood in exterior applications. Model Number: SSDWP3S305. In this version, you get a #10 x 3 in. screw in Type 305 stainless steel with packaging quantity of 1000.
What matters most here is that this screw is made for exterior work where corrosion resistance and reliable drive performance both matter. Simpson Strong-Tie positions the DWP as a fastening solution for deck, dock, and general exterior jobs where extra corrosion protection is needed. For anyone building or repairing deck boards, trim details, or other exposed wood assemblies, that makes this a purpose-built option rather than a general-use screw trying to cover every job.
The thread design is one of the real selling points. The DWP uses Simpson Strong-Tie’s box thread pattern with raised-ridge technology, and the practical benefit is lower driving torque. That means the screw is engineered to drive with less effort while still giving the holding performance expected in wood-to-wood fastening. On repetitive deck fastening, less resistance at the driver adds up to faster work and less strain on the tool.
The sharp point is there for a reason too. Instead of fighting to start in harder deck stock, the specially designed point is made to penetrate hardwood products more easily. That helps the screw start cleanly and stay on line as you drive, which is especially useful when you are laying a lot of boards and want consistent starts without wasted motion.
Drive engagement is another place this screw makes sense for production work. It uses a T25 6-lobe drive, which helps reduce cam-out compared with less secure recess styles. In plain terms, the bit stays engaged better, the screw drives easier, and you are less likely to chew up the head when working fast. Simpson Strong-Tie also notes that this drive style helps extend bit life, which matters when you are running through box after box on a deck build.
The head and overall geometry are set up for finished wood surfaces. This screw uses a flat head with a 0.340 in. head diameter, making it a fit for deck and trim applications where you want the head to seat properly rather than stand proud. Combined with the sharp point and box threads, the design is clearly aimed at getting the fastener into wood efficiently and leaving a clean finished result.
This specific screw is part of the Quik Drive collated fastening system and is listed as compatible with the Quik Drive PRO300SG2. That matters because this is not just a loose deck screw sold in bulk. It is intended for contractors and serious users who want the speed benefits of collated fastening for larger jobs. If you are already on the Quik Drive platform, this is a straightforward fit for exterior deck screw work in the listed size and material.
Simpson Strong-Tie also backs the line with testing data, noting the screw is tested in accordance with ICC-ES acceptance criteria AC233 and load rated for withdrawal resistance. For the 3 in. #10 version, the published table lists 480 lb allowable screw tension and 130 lb/in allowable withdrawal. Those are the kinds of numbers pros look for when they want more than a vague “outdoor screw” label.
Who should buy this? It makes the most sense for deck builders, remodelers, carpenters, dock crews, and serious DIY users doing exterior wood projects with a Quik Drive setup. If you need a collated deck screw that is made for wood-to-wood fastening, has stainless protection for outdoor use, and is designed to drive easier in common deck materials, this one is aimed right at that job.
Designed to Drive Easier in Deck Stock
The thread profile is doing real work here. Simpson Strong-Tie uses a raised-ridge box thread to cut driving effort while still giving the holding power needed for wood-to-wood deck fastening.
- Box thread design helps reduce driving torque
- Built for wood-to-wood fastening in decks, docks, and exterior assemblies
Better Bit Engagement, Less Cam-Out
When you are running fasteners all day, recess quality matters. The T25 6-lobe drive is made to keep the bit seated better during driving, which helps reduce stripped heads and wasted time.
- T25 6-lobe drive type
- Designed to help prevent driver-bit cam-out and extend bit life
Built for Fast Starts in Harder Wood
A screw that starts cleanly saves time on every board. The sharp point is specifically designed to penetrate hard wood products more easily, which helps the fastener begin straight and drive with less fighting.
- Sharp point style for easier penetration
- Well suited for the majority of wood used in today’s deck boards
