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 7/8"-9 hex head cap screw — a high-strength fastener built to handle demanding assemblies with steady, dependable performance. Crafted from heat-treated steel and graded as 8, this bolt is engineered for heavy-duty applications where strength and consistency matter, from woodworking and metal fabrication to automotive repairs and structural fittings.

What sets this screw apart:

  • Diameter and thread: 7/8 inch diameter with 9 threads per inch (7/8-9), a coarse thread that bites firmly into softer materials and speeds up installation.
  • Length: 2-1/2 inches, providing a robust engagement without protruding beyond the assembly.
  • Material and finish: heat-treated steel delivering high hardness and reliable wear resistance, aligned with Grade 8 strength for demanding loads.
  • Head and point: hex head designed for easy driving with standard wrenches or sockets; blunt point aids alignment and starting in pre-drilled holes.
  • Packaging: boxed packaging keeps the fasteners organized and protected during storage and transit.

Ideal uses include medium-to-heavy duty connections where a secure clamp is essential: wood-to-metal furniture frames, mounting brackets for machinery, trailer and structural assemblies, and other applications that require a tough, maintenance-friendly fastener. The Hillman hex head cap screw provides a reliable clamping force and enduring performance under vibration and load, making it a go-to choice for professionals and serious DIYers alike.

Why choose Hillman for this fastener? It combines a proven track record with precise manufacturing standards, ensuring consistent dimensions, reliable thread engagement, and compatibility with standard tools. For projects that demand a sturdy, high-strength bolt without fuss, this 7/8"-9 hex head cap screw is a practical, trusted option.
