Key Features

Fast Starts in Wood The SawTooth Type-17 point starts quickly and helps reduce driving effort, so you can move through framing and general wood fastening with less fighting at the start of each screw. Positive Bit Engagement The T25 six-lobe drive gives the bit a solid grip in the head. That means easier driving, less cam-out, and longer bit life when you are running a lot of structural screws. Built for Indoor or Outdoor Use Quik Guard coating helps protect the Simpson Strong-Tie framing screw in both indoor and outdoor projects, making it a practical choice for remodeling, framing, and exterior work.

Overview

The Simpson Strong-Tie SDWS16300QMB Strong-Drive SDWS Framing Screw is a 3 in. structural wood screw sold in a 250-piece pack for wood-to-wood fastening in framing, remodeling, and general construction. This is a framing screw designed for fastening wood to wood in structural framing and general indoor or outdoor building work. Model Number: SDWS16300QMB. If you want the holding power and pull-out resistance of a structural screw with the convenience of driving and removing it with a bit, this is the kind of fastener you buy instead of reaching for nails.

What matters here is how the design helps on the job. The SawTooth Type-17 point is built for fast starts and reduced installation torque, which means less effort getting the screw moving and less need for predrilling in most applications. The T25 six-lobe drive is there for a reason too: better bit engagement means easier installation and less chance of stripping the recess when you are driving a lot of screws in sequence.

The head design is just as important as the point and drive. This screw uses a low-profile washer head with underhead box nibs to increase bearing in structural applications while still giving you clean countersinking. In practical terms, that helps clamp material down well without the head disappearing like a typical countersunk wood screw. On framing members, blocking, and similar connections, that broader bearing surface is one of the reasons this style works so well.

The screw measures 0.160 in. in shank diameter and 3 in. overall length, with a 1-5/8 in. thread length. That size puts it right in the sweet spot for a lot of common framing and remodeling work where you need meaningful grip without jumping to a heavier timber fastener. Simpson Strong-Tie also states that the SDWS Framing screw is designed and load-rated as a replacement for 16d, 10d, and 8d nails in framing applications, and it is code listed under IAPMO UES ER-192 for several common wood framing uses.

For real-world durability, Quik Guard coating gives the screw added protection for indoor and outdoor applications. That makes it a flexible option for interior framing, exterior repairs, deck-related wood fastening, and engineered wood applications where corrosion resistance matters but you still want a screw that drives quickly. The coating is part of why these make sense for contractors and serious DIY users who do not want separate screw types for every basic wood project.

This SDWS framing screw is a strong fit for carpenters, remodelers, deck builders, general contractors, and homeowners doing structural wood projects. If your job involves fastening dimensional lumber, engineered wood, posts, rails, blocking, or framing members and you want more holding power, better pull-down, and the option to back the fastener out if something needs adjusting, this screw makes a lot of sense. It is especially useful for anyone who is tired of nails when layout changes, rework, or tight-fitting assemblies are part of the job.

Drive Structural Connections with More Control

This screw is made for wood framing work where you want the holding power of a structural fastener without giving up speed. It starts fast, pulls material together well, and gives you the option to remove and reposition if needed.

• Designed for wood-to-wood and engineered-wood applications
• Load-rated to replace 16d, 10d, and 8d nails in several framing applications

Get a Cleaner, Stronger Seat at the Head

The washer-style low-profile head is not just a shape choice. It gives the screw more bearing surface at the connection while the underhead box nibs help it seat cleanly into the wood.

• Low Profile Head with underhead box nibs for increased bearing
• Head diameter is 0.450 in. for better load distribution than a typical narrow wood screw head

Start Faster and Keep the Bit Hooked Up

When you are driving a lot of screws, small design details matter. The SawTooth point helps the screw bite quickly, while the T25 six-lobe drive helps keep the bit engaged so you waste less time fighting slips and stripped recesses.

• SawTooth Type-17 point helps eliminate predrilling in most applications
• T25 six-lobe drive is built for positive engagement and longer bit life
