Key Features

Drives With Less Force The redesigned point and thread pattern helps the screw start easier and requires up to 25% less driving torque. That means less strain on your Quik Drive setup and more screws driven per battery charge. Cleaner Subfloor Fastening This subfloor collated screw uses a deep T25 6-lobe recessed ribbed head for clean countersinking and better bit retention. Fewer cam-outs means a more consistent drive when you are covering floor quickly. Helps Stop Squeaks The Simpson Strong-Tie Strong-Drive Subfloor Collated Screw, #9 x 2-in. T25, Yellow Zinc, 1000-Pack (HCKWSV2S) is built to pull subfloor tight to the joist. Better holding power helps reduce the gaps that lead to floor squeaks later.

Overview

The Simpson Strong-Tie Strong-Drive Subfloor Collated Screw, #9 x 2-in. T25, Yellow Zinc, 1000-Pack (HCKWSV2S) is a collated wood screw made for fastening subfloor and sheathing in wood-to-wood applications with the Quik Drive auto-feed system. This is a collated subfloor screw designed for fast wood-to-wood subfloor fastening. Model Number: HCKWSV2S. If you are laying a lot of OSB or plywood and want speed, consistent seating, and fewer call-backs for squeaks, this is the fastener this system was built around.

What matters here is not just that it is a #9 x 2 inch screw. It is the thread and point design that changes how the job feels. Simpson states the redesigned point and thread pattern provides easy starts, requires up to 25% less driving torque, and can deliver up to 20% faster installation. On the floor, that means the screw feeds and bites with less fight, which helps when you are driving hundreds or thousands of screws in a day.

The head design is equally important for subfloor work. The deep T25 6-lobe recessed ribbed head is built for secure bit engagement and clean countersinking. In plain terms, the bit stays planted better, you get fewer cam-outs, and the head seats more consistently below the surface without tearing up the panel face. That is the kind of small detail that saves real time when you are trying to keep production moving.

This screw is also designed around the real reason subfloor fasteners matter: floor performance after the house is closed in. Simpson calls out the holding power of the WSV design as a way to reduce the gaps between joist and subfloor that cause floor squeaks. That makes this a practical choice for framing crews, subfloor installers, and remodelers who want a tighter deck and fewer issues after the job is done.

The HCKWSV2S version uses a yellow-zinc coating and a 2/3-threaded shank with a variable thread design and high-low threaded point. The combination is aimed at fast starts, strong pull-down, and reliable wood-to-wood fastening. It also uses a rimmed flat head with nibs and a 0.333 inch head diameter, which helps the screw seat cleanly in subfloor material while still giving solid bearing at the surface.

Because this is a collated screw, system fit matters. The HCKWSV2S is compatible with Quik Drive PRO200S, PRO250G2, PRO300S, and Project Pro tools. If you are already running one of those Quik Drive setups, this is an easy fit for production subfloor fastening. If you are not using the Quik Drive platform, this is not the screw to buy just because the price looks good. It is built to work as part of that auto-feed system.

Another practical advantage is serviceability. Simpson notes these WSV screws can be backed out easily for future access to floor cavities. That is useful on jobs where plumbing, wiring, or corrections may need access later. You still get the holding power needed for subfloor work, but you are not locking yourself into a fastener that becomes a headache if the floor has to come back up.

Who should buy it? Pros doing production subfloor and sheathing work will get the most out of it, especially crews already invested in Quik Drive equipment. Serious DIY users tackling a large floor project with a compatible Quik Drive tool can also benefit, but this product makes the most sense when speed, consistency, and reduced tool wear are worth paying for. If your goal is faster installation with a screw specifically engineered for subfloor performance, this is the right lane.

Built for Fast Floor Work

This screw is meant for production work, not one-at-a-time fastening. In a compatible Quik Drive setup, the collated strip format helps keep you moving across subfloor without stopping to reload loose screws constantly.

• Designed for subfloor and sheathing projects
• Up to 20% faster installation based on Simpson test data

Better Bite, Less Wear on the Tool

The redesigned tip and thread pattern is there to make starts easier and reduce the force needed to drive each screw. On large floor layouts, lower torque demand means less stress on the driver and less fatigue over the course of the day.

• Requires up to 25% less driving torque in Simpson test data
• Less torque can mean less wear on tools and more screws driven per battery charge

Clean Countersinking Matters

Subfloor screws need to seat cleanly and hold tight. The deep T25 6-lobe head and ribbed head design are aimed at better bit retention and a cleaner finish at the panel surface, which helps when you want consistent results row after row.

• Deep T25 6-lobe recessed ribbed head for secure engagement
• Helps reduce cam-outs and supports clean countersinking

Pro Tip

If you are already on a compatible Quik Drive setup, stick with the T25 bit and keep an eye on countersink consistency as the bit wears. This screw is designed to seat cleanly, so when the head starts looking rough or shallow, a fresh bit usually fixes it fast.

Tool Nut’s Take

Tool Nut’s Take

Fast Floor Work Without Fighting the Screw

The Simpson Strong-Tie Strong-Drive Subfloor Collated Screw, #9 x 2-in. T25, Yellow Zinc, 1000-Pack (HCKWSV2S) makes the most sense for crews who want faster subfloor installation and a screw that is actually engineered for that job.

• Who it’s for: Framers, subfloor crews, remodelers, and contractors already using compatible Quik Drive auto-feed tools.
• Why it stands out: Lower driving torque, faster installation, clean countersinking, and holding power aimed at reducing squeaks are the real reasons to buy this one.
• Worth knowing: This is a system-specific collated screw, so it is a smart buy if you are on Quik Drive. If you are not, buy for your driver first, not just by screw size.

Common Questions
