Key Features

Drives With Less Effort The redesigned point and thread pattern starts easier and needs up to 25% less driving torque. That means less strain on the tool and faster screw installation across subfloor runs. Cleaner Countersinking A deep T25 6-lobe recessed ribbed head gives the bit a more secure seat and helps cut down on cam-out. You get a cleaner set in subfloor panels with less fighting the fastener. Built for Quiet Floors The Simpson Strong-Tie WSVF2S Strong-Drive WSVF SUBFLOOR Screw is made for wood-to-wood subfloor fastening. Strong holding power helps pull the subfloor tight to the joist to reduce the gaps that lead to floor squeaks.

Overview

The Simpson Strong-Tie WSVF2S Strong-Drive WSVF SUBFLOOR Screw is a collated wood screw for the Quik Drive auto-feed system, sized at #9 x 2 in. and sold in a 2,000-count package. This is a collated subfloor screw designed for fastening wood subfloor and sheathing to wood framing. Model Number: WSVF2S. If you are laying down a lot of floor and want fewer squeaks, faster installation, and the ability to back screws out later if needed, this is the right kind of fastener.

What matters here is not just the size. Simpson reworked the point and thread pattern so the screw starts easier and needs up to 25% less driving torque in single-material LVL, with test data also showing up to 20% faster installation. On the job, that means less tool strain, less battery drain on cordless-compatible driving setups, and less wasted time when you are running long rows of subfloor screws.

The head design is doing real work too. The deep T25 6-lobe recessed ribbed head improves bit retention and helps reduce cam-out, which is exactly what you want when you are driving collated screws in repeated cycles. The rimmed flat head with nibs is built to countersink cleanly, so the subfloor lays down tight without proud fasteners creating problems for finish flooring later.

This screw uses a variable thread design with a high-low threaded point and a 2/3-threaded shank. That combination is aimed at pulling material together efficiently instead of just boring its way in. For subfloor work, that pull matters because it helps close the gap between the joist and the panel. That is the whole reason screws outperform nails in squeak-prone floor assemblies.

The WSVF2S is also practical when the job changes later. Unlike fasteners that are basically there for good, these WSVF screws can be backed out, which gives you a way back into floor cavities for repairs, additions, or inspection. Electricians, plumbers, remodelers, and service crews all appreciate that when a finished floor has to come back up in one section without turning the area into a demolition project.

System fit is important with collated fasteners, and this screw is made for Simpson Strong-Tie Quik Drive tools including the PRO200S, PRO250G2, PRO300S, and Project Pro systems. That makes it a good match for crews already running Quik Drive equipment and looking for a dedicated subfloor fastening screw instead of trying to force a general-purpose collated screw into the job.

The coating on this WSVF2S version is Quik Guard, and the packaging quantity is 2,000 screws per collated load package. For production framing and decking-style floor assembly work, that kind of pack size makes sense because you are buying for throughput, not for a one-room patch. This is a fastener for builders, framers, and remodelers who want repeatable results over a lot of square footage.

If you are using a Quik Drive setup for subfloor fastening, this screw earns its place by solving the three things that slow crews down: hard starts, bit slip, and callbacks for noisy floors. It is best for contractors who care more about install speed and floor performance than saving a few dollars on generic collated screws.

Fast Subfloor Installation with the Quik Drive System

This collated screw is built for production floor work. Paired with a Quik Drive auto-feed screw gun, it keeps the install moving without stopping to hand-load individual fasteners.

• Collated format designed for Simpson Strong-Tie Quik Drive tools
• Up to 20% faster installation based on Simpson test data
• 2,000-count packaging supports large subfloor runs

Starts Easier and Reduces Tool Strain

The redesigned tip and thread pattern are there to make driving smoother, especially over long sections of wood-to-wood fastening where tool fatigue adds up fast.

• Requires up to 25% less driving torque in single-material LVL
• Less torque means less wear on the driving tool
• Helps get more screws driven per battery charge on cordless-capable systems

Made to Pull Panels Down Tight

Subfloor screws need to do more than sink flush. They need to clamp the panel to the joist, stay engaged, and resist the little movements that turn into squeaks later.

• Variable thread design helps draw wood members together
• 2/3-threaded shank supports panel pull-down
• Holding power helps reduce joist-to-subfloor gaps that cause noisy floors

Pro Tip

If you are chasing squeak-free floors, keep your screw lines centered on the joists and use the WSVF2S where the 2 in. length matches your panel and framing stack-up. The screw can be backed out later, so it is a smart choice anywhere you may need access under the floor down the road.

Tool Nut's Take

Tool Nut's Take

Simpson Strong-Tie WSVF2S Strong-Drive WSVF SUBFLOOR Screw Gets the Job Done Faster

This is the kind of collated subfloor screw that makes sense for crews who install a lot of floor and do not want callbacks for squeaks.

• Who it's for: Framers, builders, and remodelers using Simpson Quik Drive systems for subfloor and sheathing work.
• Why it stands out: Lower driving torque, faster install speed, secure T25 engagement, and strong panel pull-down are exactly what matter in production subfloor fastening.
• Worth knowing: This is a system-specific collated fastener, so make sure your Quik Drive model matches. If you are not running a compatible auto-feed driver, this is not the right screw for the job.

Common Questions
