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

Trust Hillman to secure your projects with a bolt you can rely on. The Hillman 1/2 in x 4 in Zinc Plated Steel Hex Tap Bolt is built for durable, quick-fastening joints in metal-to-metal assemblies, furniture repairs, and heavy-duty DIY tasks. With a robust Grade 2 carbon steel core and a protective zinc finish, these bolts are designed to perform where durability and rust resistance matter most.

Why this hex tap bolt stands out

  • Precise dimensions for versatile use: 1/2 inch diameter with a 4 inch length gives you a bold fastening option that fits a wide range of tapped holes and through-holes paired with nuts.
  • Full thread for secure bite: The coarse thread profile grips quickly and evenly, delivering strong clamping power and reliable engagement in both metal and compatible materials.
  • Corrosion resistance you can count on: Zinc plating shields the steel from moisture and everyday wear, extending service life in indoor, workshop, and light outdoor environments.
  • Convenient packaging for ongoing projects: A boxed presentation of 25 pieces keeps your toolbox organized and ready for multiple assemblies without constant reordering.
  • Brand you can trust: Hillman’s hardware lineage reflects practical design choices aimed at real-world building, repair, and maintenance needs.

Ideal applications

  • Mounting metal brackets, supports, or fixtures to steel frames or pre-threaded components
  • Repairing furniture frames or equipment where a strong, fully threaded fastener is required
  • Assembling small machinery or DIY projects that use tapped holes or paired with matching nuts
  • Quick replacement for worn or stripped bolts in garage, shop, or workshop environments

Practical guidance for best results

  • Pair with standard hex wrenches or sockets sized for 1/2 in hex heads to ensure a solid, slip-free turning experience.
  • Lubricate threads lightly when assembling into metal-to-metal joints to reduce friction and protect the plating over time.
  • Avoid overtightening to prevent thread stripping or damage to tapped holes; tighten to a snug, secure fit based on your material’s strength and application.

Whether you’re upgrading hardware in a shop project, repairing equipment, or putting together a sturdy metal-framed project, the Hillman 1/2 in x 4 in Zinc Plated Steel Hex Tap Bolt (25 pk) delivers dependable performance, practical longevity, and organized convenience in one boxed set.
