Key Features

316 Stainless Build Made from Type 316 stainless steel for deck, dock, and other exterior jobs where corrosion resistance matters. This is the version you want for seaside exposure and harsh outdoor conditions. Drives Easier The box thread design with raised-ridge technology helps reduce driving torque. That means less strain on the tool and smoother fastening in common decking woods. Collated Wood Screw System This Simpson Strong-Tie collated wood screw is built for Quik Drive installation with a T25 6-lobe drive that helps cut down cam-out. That translates to faster runs and longer driver-bit life.

Overview

The Simpson Strong-Tie SSDWP3S316 Deck-Drive DWP Wood SS Screw is a collated exterior wood screw made for wood-to-wood fastening in decking and other outdoor builds. This is a wood screw designed for fastening deck boards, dock boards, trim, and other exterior wood components with a Quik Drive auto-feed system. Model Number: SSDWP3S316.

This specific version is a #10 x 3 in. screw made from Type 316 stainless steel, which matters if the job is near salt air, moisture, or other corrosive conditions. Simpson Strong-Tie calls out seaside applications directly, so this is not just a general exterior fastener with a coating. It is a stainless option intended for jobs where long-term corrosion resistance is a real concern.

On the driving side, the DWP design uses a unique box thread with raised-ridge technology to reduce driving torque. In plain terms, that helps the screw pull in easier, especially when you are running a lot of fasteners in a row. The sharp point is designed to penetrate hardwood products more easily, which helps when you are working with tougher deck boards and do not want to fight each start.

The drive interface is a T25 6-lobe design. That setup helps reduce cam-out compared to more basic drive styles, which means the bit stays engaged better under load and the head is less likely to strip during repetitive fastening. Simpson Strong-Tie also notes that this helps extend bit life, and the replacement bit for the system is BITTX25.

From a head design standpoint, this screw uses a flat head with a 0.340 in. head diameter. That gives it the profile you want for deck and trim work where the fastener should seat cleanly rather than stand proud. It is also collated, so it is built for fast, repetitive installation instead of hand-feeding loose screws one at a time.

The SSDWP3S316 is listed as compatible with the Quik Drive PRO300SG2. If you are already on that platform, this screw fits neatly into a production-style decking workflow. Packaging quantity is 1000 screws, which makes this a contractor-friendly box for larger runs rather than a small repair pack.

Simpson Strong-Tie also states these screws are tested in accordance with ICC-ES AC233 acceptance criteria and are load rated for withdrawal resistance. The published values for the #10 x 3 in. version include 480 lb allowable screw tension and 130 lb/in allowable withdrawal. If the job calls for data-backed fastening performance instead of just a generic deck screw, that matters.

Who should buy it? This one makes the most sense for deck builders, marine-adjacent contractors, remodeling pros, and serious DIY users who want a collated deck screw for exterior wood-to-wood work and need better corrosion resistance than a standard coated fastener. If you are building inland and do not need Type 316 stainless, there may be cheaper options. If the project is exposed and you want the right material from the start, this is the smarter buy.

Thread Design That Cuts Driving Effort

The thread pattern is doing real work here. Simpson Strong-Tie designed the box thread with raised-ridge technology to reduce driving torque, which helps the screw run smoother during repetitive deck fastening.

• Box thread design helps reduce driving torque
• Built for wood-to-wood fastening in decking, docks, and boardwalks

Better Bit Engagement at the Head

The T25 6-lobe drive is there to keep the bit planted and reduce cam-out when you are driving fasteners all day. That means cleaner engagement, less chewed-up heads, and less wasted time swapping worn bits.

• T25 6-lobe drive type
• Flat head design for a clean finished seat

Sharp Point for Tougher Decking Woods

The point geometry is meant to start cleanly and penetrate hard wood products with less fighting at the beginning of the drive. That is especially useful when you are working through a big box of screws on decking or trim.

• Sharp point helps start faster in wood
• 3 in. length suits common exterior wood-to-wood fastening tasks

Pro Tip

If you are buying this box for production decking, keep a BITTX25 replacement bit on hand from day one. The T25 6-lobe drive is designed to reduce cam-out, but fresh bits still make a difference when you are burning through hundreds of fasteners in a shift.
