About Product Overview

Anchoring a ledger board, post base, or heavy fixture into concrete or masonry calls for a bolt that won't back out or shear under load, and that's the job this GRK Fasteners anchor bolt is built for. The hex head gives you a solid grip for a wrench or socket, letting you drive it home with real torque instead of stripping out like a slotted or Phillips head would.

At 7 inches long and 1/2 inch in diameter, it's sized for anchoring through framing and into a concrete or masonry base, with a coarse thread pattern designed to bite and hold in that material. Match it to a 1/2 inch drill hole for proper fit and full holding strength. Made from steel and sold boxed, one bolt per package.

  • Head Style: Hex
  • Material: Steel
  • Length: 7 inches
  • Diameter: 1/2 inch

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.
