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.

About Product Overview

Introducing the Hillman 5/8 in. D x 5 in. L Zinc Plated Steel Hex Bolt — a durable, general-purpose fastener designed to tackle everyday projects with confidence. Built for reliability, this hex bolt blends practical strength with easy installation, making it a staple for DIY enthusiasts, hobbyists, and professionals alike.

Why this hex bolt stands out

  • Generous 5/8 in head diameter provides a solid drive surface for standard hex wrenches, delivering consistent torque and reducing the risk of cam-out during installation.
  • Zinc-plated steel finish offers corrosion resistance in indoor environments and sheltered outdoor settings, helping your joints stay secure over time.
  • Grade 2 construction delivers dependable, general-purpose strength for framing, shelving, furniture assembly, and everyday hardware tasks.
  • Coarse threads bite quickly into soft woods and many pre-threaded metal applications, enabling faster assembly with fewer pre-drilled holes.
  • 5-inch length accommodates thick stock and through-bracket connections, giving you flexibility on a variety of projects—from furniture frames to deck components.
  • Boxed package of 25 provides ready-to-use quantity for small jobs or bulk stocking, ensuring you’re prepared when inspiration strikes.

Ideal use cases

  • Wood-to-wood connections in furniture frames, cabinetry, and shelving units.
  • Decking, railing, and outdoor projects where mild weather exposure is a consideration (thanks to zinc plating).
  • Through-bracket assemblies and other hardware installations that require solid, reliable fasteners.

Practical tips for best results

  • Pair with a matching nut and washer when securing through holes to maintain a clean, flush finish.
  • Pre-drilling is recommended for hardwoods to prevent splitting, while soft woods can often accept the coarse thread without a pilot hole.
  • Store the box in a dry, temperate space to preserve the zinc finish and prevent rust over time.

Their Counter
Try local first · we'll wait

The stores we send you to are local and independently run — often for generations, the kind of place where someone behind the counter knows the regulars. We don't own them. We just think they deserve the foot traffic. They can put most of what we sell on their next truck. Ask there before you check out here.

About our directory. National Hardware Group is an independent retailer and directory. The local stores we list and link to are separately owned and operated — we have no ownership stake in any of them, and most pay us nothing to be included. That includes plenty of stores flying a co-op banner that people don't realize are locally owned and run, not operated by a corporation. Store owners can choose to upgrade their listing for an enhanced presence or pickup features, but the base directory is free, and inclusion is never a paid endorsement.
