Simpson Strong-Tie Strong-Drive Subfloor Collated Screw, #9 x 2-in. T25, Yellow Zinc, 2000-Pack (WSV2S)

Key Features

Drives With Less Effort The redesigned point and thread pattern helps the screw start easier and cut driving torque by up to 25%. That means less strain on the driver and faster subfloor fastening. Cleaner Set, Fewer Cam-Outs A deep T25 6-lobe recess and rimmed flat head with nibs give you better bit engagement and clean countersinking. That helps keep the screw seated where it belongs instead of skating or stripping. Built for Subfloor Work The Simpson Strong-Tie WSV2S Strong-Drive WSV SUBFLOOR Screw is a collated wood screw made for wood-to-wood subfloor and sheathing jobs with the Quik Drive system. Its holding power helps reduce the joist-to-subfloor gaps that lead to floor squeaks.

Overview

The Simpson Strong-Tie WSV2S Strong-Drive WSV SUBFLOOR Screw is a collated interior wood screw for fastening subfloor sheathing in wood-to-wood applications with compatible Quik Drive auto-feed screw driving tools. This is a collated subfloor screw designed for subfloor fastening and sheathing installation. Model Number: WSV2S. If you are laying down OSB or plywood over framing and want a faster, more controlled alternative to loose screws, this is the setup Simpson built this fastener around.

For the WSV2S version specifically, you are getting a #9 x 2 inch yellow-zinc coated steel screw in a 2,000-count collated strip format. That matters because the size is right in the wheelhouse for common interior subfloor fastening, and the collated format is what keeps production moving when you are working floor after floor. Instead of stopping to handle individual fasteners, the screws feed through the Quik Drive system and keep the installer upright and moving.

One of the biggest improvements called out by Simpson Strong-Tie is the redesigned point and thread pattern. Test data states the screw can require up to 25% less driving torque and deliver up to 20% faster installation. On the job, that translates into easier starts, less tool wear, and more screws driven per battery charge or less strain on a corded setup. Lower driving force also helps when you are running long stretches of subfloor and need a screw that keeps pace without fighting the tool.

The head design is just as important as the thread. This screw uses a deep T25 6-lobe drive with a rimmed flat head with nibs. In practical terms, that gives the bit a more secure seat and helps reduce cam-outs when the tool is feeding and driving in quick succession. The head is made to countersink cleanly, which is what you want on subfloor work where proud fasteners can telegraph through finished flooring or create headaches later in the build.

The shank and thread geometry are purpose-built for subfloor performance. Simpson lists a 2/3-threaded shank, variable thread design, and high-low threaded point. That combination is there to start quickly, pull materials together, and hold the subfloor tight to the joist structure. Strong holding power is not just a number on a chart here. It is directly tied to reducing the small gaps between joist and panel that often turn into squeaks once the house is finished and lived in.

Another practical advantage is serviceability. Unlike nailed subfloors that can be a hassle to undo cleanly, WSV screws can be backed out when future access to floor cavities is needed. That is useful for remodelers, repair crews, and anyone who has ever had to open up a section of floor after the fact for plumbing, electrical, or inspection work.

System fit matters with this product because this is not a loose-box screw meant for any random driver. The WSV2S is designed for the Quik Drive system and is listed as compatible with the Quik Drive PRO200S, PRO250G2, PRO300S, and Project Pro tools. If you already run one of those tools, this screw makes sense as a direct consumable for production flooring work. If you do not, this is a fastener you buy specifically because you want the speed and ergonomics of an auto-feed subfloor fastening setup.

Bottom line: this screw is best for framers, subfloor crews, general contractors, and serious remodelers doing interior wood subfloor or sheathing installation at scale. If your priority is fast feed, easy starts, solid pull-down, and fewer squeaks than a nailed floor, the WSV2S is the kind of collated screw that earns its keep. If you are not using a compatible Quik Drive tool, look elsewhere, because this product is built around that platform.

Fast Subfloor Installation With the Quik Drive System

This screw is built for production floor work, not one-at-a-time fastening. In a compatible Quik Drive setup, the collated strip keeps you moving across the deck without constantly reaching for loose screws.

• Collated screw format for Quik Drive auto-feed fastening
• Designed for subfloor and sheathing projects in wood-to-wood applications

Starts Easier and Cuts Down on Tool Strain

The redesigned point and thread pattern is not just spec-sheet filler. It is there to get the screw started faster and reduce how hard the tool has to work on every drive.

• Up to 25% less driving torque based on Simpson test data
• Up to 20% faster installation from the redesigned thread pattern

Designed to Pull Panels Down Cleanly

The head, point, and thread design work together to seat the screw cleanly and hold the panel tight. That is the stuff that matters when you are trying to avoid callbacks for movement or squeaks.

• Deep T25 6-lobe recess for secure bit retention and fewer cam-outs
• Holding power helps reduce gaps between joist and subfloor that can cause squeaks

Pro Tip

If you are chasing floor squeaks, do not focus only on screw spacing. Use the WSV2S where the panel is fully seated to the joist and let the variable thread design pull the sheet down tight, because that tight joint is what helps this screw do its best work.
