Key Features
Built for Framing The Simpson Strong-Tie SDWS16300Q Strong-Drive SDWS Framing Screw is a structural wood screw made for wood-to-wood fastening. It is designed as a load-rated alternative to common framing nails in many framing applications. Fast Starts The SawTooth Type-17 point starts quickly, cuts installation torque, and eliminates predrilling in most applications. That means faster driving and less fighting the screw on the job. Cleaner Seating A low profile washer head with underhead box nibs gives more bearing surface in structural connections while helping the head countersink cleanly. You get solid pull-down without the head disappearing like a typical bugle-head screw.
Overview
The Simpson Strong-Tie SDWS16300Q Strong-Drive SDWS Framing Screw is a 3 inch structural wood screw built for wood-to-wood fastening in framing, remodeling, and indoor or outdoor projects. This is a framing screw designed for structural wood fastening. Model Number: SDWS16300Q. If you want the holding power and pull-out resistance of a structural fastener with the serviceability of a screw, this is the kind of fastener you reach for.
What matters here is not just that it is 0.160 inch in diameter and 3 inches long, but how that translates on the job. Simpson rates the SDWS Framing screw as a code-listed, multi-purpose structural fastener and positions it for replacing common 16d, 10d, and 8d nails in a range of framing applications. For contractors and serious DIY users, that means a fastener that pulls material tight, holds well, and can be backed out if you need to correct a layout mistake.
The point design is a big part of why these drive easier than many structural screws. The SawTooth Type-17 point is made for fast starts and reduced installation torque, so you spend less time leaning on the drill or impact driver and less time predrilling. In most applications, predrilling is not needed. That matters when you are running a lot of fasteners in framing lumber, treated material, or engineered wood and want to keep the pace up.
The head design is also doing real work. Instead of a standard drywall-style head, this screw uses a low profile washer head with underhead box nibs. The wider bearing surface helps in structural connections, while the nibs help the head seat more cleanly into wood. In practical terms, you get strong clamping action and cleaner countersinking without crushing the material the way the wrong screw head can.
Drive engagement is another area where this screw earns its keep. The T25 6-lobe drive gives more positive bit engagement than a basic Phillips-style recess, which helps reduce slipping under load and can extend bit life. When you are driving long screws repeatedly into framing lumber, stable bit engagement means fewer stripped heads, less wasted motion, and fewer stops to swap bits.
For jobsite durability, Simpson uses Quik Guard coating for indoor and outdoor applications. That makes this a practical choice for framing, general wood construction, remodeling, and exterior wood projects where corrosion resistance matters more than it would with an untreated interior-only fastener. It is not just about shelf specs. It is about using one structural wood screw across a wider range of jobs without second-guessing whether the finish is up to it.
The thread layout is tuned for wood connections as well. This version uses serrated threads with a 1-5/8 inch thread length, which helps the screw bite and advance through wood efficiently. Combined with the 0.450 inch head diameter and 0.160 inch shank diameter, it is sized for real framing work, not light trim or cabinet duty. This is a fastener for structural members, blocking, general framing repairs, remodel punch work, and other wood-to-wood connections where strength and pull-down matter.
If you buy fasteners by the case and do enough work to care about consistency, the packaging matters too. This SDWS16300Q pack includes 1,000 screws, which makes sense for crews, shop stock, deck and framing work, or anyone who does not want to run short mid-job. Bottom line: this is a purpose-built structural framing screw for carpenters, remodelers, deck builders, and serious DIY users who want better holding power, easier rework, and a cleaner drive than nails can offer.
Drive Faster Into Framing Lumber
This screw is built to save time when you are fastening framing lumber, blocking, or general wood connections. The point starts quickly and the drive recess stays engaged so you can keep moving instead of fighting the fastener.
- SawTooth Type-17 point helps eliminate predrilling in most applications
- T25 6-lobe drive gives more positive bit engagement during installation
Pull Material Tight Without a Bulky Head
The head is one of the main reasons this screw works well in structural wood fastening. It gives you more bearing at the surface while still seating cleanly into the material.
- Low profile head with underhead box nibs for increased bearing in structural applications
- 0.450 in. head diameter helps distribute load better than a narrow conventional head
Made for Real Wood-to-Wood Work
This is not a general-purpose wood screw pretending to be structural. It is a code-listed framing fastener intended for wood-to-wood and engineered-wood applications, including indoor and outdoor projects.
- Code-listed multi-purpose structural fastener
- Quik Guard coating helps protect the screw in indoor and outdoor applications

Pro Tip
Use a fresh T25 6-lobe bit and keep steady pressure as the head seats. That lets the box nibs do their job and helps the low profile head finish clean instead of skating or chewing up the recess.
