About Product Overview

Simpson Strong-Tie built these 4" structural screws for the connections that actually hold a structure together—ledger boards, beam plies, and other wood-to-wood joints where a deck screw just won't cut it. The serrated thread bites into lumber fast and the hex washer head gives a driver plenty to grab without stripping. Galvanized steel construction means they hold up indoors or outdoors, and each box comes with the correct star drive bit included so you're not hunting for the right bit mid-job.

  • Length: 4" | Diameter: 0.276" (No. 2 callout)
  • Head Type: Hex Washer | Drive: Star (bit included)
  • Thread: Serrated for fast, secure engagement
  • Finish: Galvanized steel, rated for indoor and outdoor use
  • 30 screws per box

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.
