About Product Overview

GRK's R4 is built for framing and heavy structural connections where you need a screw that won't back down under load. The No. 12/14 shank drives through 5-5/8 inches of material, giving you serious reach for multi-ply beams, ledger boards, and thick timber connections. The W-Cut thread design bites fast and self-drills, so you can skip pre-drilling on most jobs and still get a clean, split-free pull.

Climatek coating stands up to the elements, which means this screw works indoors on framing and subfloor and outdoors on decks, pergolas, and other exterior builds without rusting out on you. The Star drive gives a solid connection with the bit, cutting down on cam-out and stripped heads when you're working through tough or dense lumber. This box holds 600 screws, built for contractors and serious DIYers tackling full deck builds or framing jobs where running out mid-project isn't an option.

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 Grk Fasteners. 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.
