About Product Overview

The WSV is Simpson Strong-Tie's Strong-Drive subfloor screw, built to pull down squeaks and keep subfloor panels tight to the joists for the long haul. The #9 x 2" size in this box is sized for standard subfloor thicknesses, and the high/low thread design bites into both the panel and the framing member to resist the back-and-forth stress that causes floors to loosen up over time.

Self-drilling tips mean less pre-drilling and less snapped bits on the job, and the T25 drive gives you solid bit engagement so you're not stripping heads halfway through a room. Yellow zinc plating on steel construction stands up to the moisture that's common in subfloor applications without the cost of stainless. This is an indoor-rated fastener, so it's built for subfloor and framing work under a roof, not exterior decking exposed to weather.

Contractors and remodelers doing subfloor repair, new construction, or squeak fixes will find this a straightforward upgrade over standard wood screws or nails for this specific job.

Price check

Go ahead. Check.

You're going to price-check us against Amazon, Home Depot, and Lowe's. Everybody does. Good — open all three tabs. We'll wait. Then look hard at what you're actually being handed over there.

On Amazon, start with these four questions before you click buy.

01

Who's actually selling it

The brand name is on the listing. A different company is in the seller field. Those aren't the same thing, and the second one is who you're buying from.

02

Whether the warranty survives

Most manufacturers only honor a warranty when the unit came through an authorized dealer. We're authorized for Simpson Strong-Tie. A third-party marketplace seller usually isn't.

03

Where the box came from

Gray-market stock, returns repackaged as new, and outright fakes move through marketplaces constantly. It all looks identical in the photo. It stops looking identical when it fails.

04

Who you call when it breaks

Ours is a phone number with a person behind it who has held this product. M–F, 6 AM – 5 PM Pacific. (866) 469-8556

The big boxes don't care if your hardware store survives.

Amazon, Home Depot, and Lowe's are built to pull every hardware dollar out of your town. When the local shop can't keep the lights on, the counter where somebody actually knew which part you needed goes with it. We're built the other way: real brands so you're never stuck on a marketplace, and a straight answer to buy it down the street when that's the better call. Support independent hardware — it doesn't restock itself.

Why we tell you to shop local

Shop Local · Support Independent

Every order helps keep your local hardware store on the corner.

Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.
