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

Meet the Hillman 7/16 in. D x 2-1/2 in. L Zinc Plated Steel Hex Bolt — a dependable, general‑purpose fastener designed for everyday projects. With a zinc‑plated finish, this bolt offers solid corrosion resistance for indoor assemblies and protected outdoor use, while its Grade 2 steel delivers reliable strength at an affordable price.

Key features that matter

  • Size and build: 7/16 in diameter, 2-1/2 in length, hex bolt for easy driving with a matching socket or wrench.
  • Material and finish: Durable steel core with a zinc plating that helps resist rust and corrosion in typical workshop environments.
  • Thread type: Coarse threads provide strong grip in softer materials and faster, more forgiving threading during assembly.
  • Strength grade: Grade 2 general‑purpose steel—great for non‑structural or moderate‑duty applications where affordability and availability matter.
  • Packaging: 50 bolts per boxed package, ideal for bulk projects, inventories, and maintenance kits.

Ideal applications

  • Furniture assembly and repair, including frames, brackets, and shelving supports.
  • Wood‑to‑metal connections in DIY projects, cabinetry, and light framing.
  • General hardware tasks in workshops, garages, and storage environments where corrosion resistance is beneficial but extreme weather exposure isn’t a primary concern.

Why choose these Hillman hex bolts

This 50‑pack delivers consistent quality for bulk jobs, keeping you stocked for ongoing projects without frequent re‑orders. The zinc plating offers practical protection against rust, while the coarse threads ensure smooth installation even when working with softer materials. If you need a reliable, budget‑friendly fastener for everyday woodworking, metal framing, or fixture mounting, these hex bolts are a solid fit.

Practical guidance

  • Pair with compatible nuts and, when needed, washers to distribute load and protect surfaces.
  • Pre‑drill pilot holes appropriately for wood to prevent splitting and to ensure clean threading.
  • Avoid overtightening to preserve thread engagement and finish integrity.
