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.

About Product Overview

Meet the Hillman 3/4 in. Dia x 1-1/2 in. L Heat Treated Steel Hex Head Cap Screw, a purpose-built fastener designed for demanding projects. This 20-pack, boxed for easy dispatch and storage, combines strength, precision, and practical design to tackle heavy-duty mounting, framing, and equipment installations with confidence.

  • Grade 8, heat-treated steel delivers superior tensile strength and wear resistance, standing up to rugged assemblies and demanding environments.
  • 3/4 in. hex head diameter provides a robust seating surface and smooth engagement with standard wrenches or sockets, reducing cam-out during tightening.
  • 1-1/2 in. length offers ample thread engagement for thicker materials and solid clamping, while still fitting into a variety of pre-drilled holes or tapped connections.
  • Coarse thread facilitates quicker installation and strong bite in softer metals or when paired with appropriate nuts and washers.
  • Boxed 20-pack ensures you’re equipped for multiple tasks—great for ongoing projects, maintenance work, or bulk inventory in workshops or job sites.
  • Versatile application—ideal for heavy-duty mounting, structural connections, bracket assemblies, and equipment installations where dependable strength is essential.

Why this Hillman hex head cap screw stands out: the heat-treated finish and Grade 8 composition deliver reliable, repeatable performance under load, so you can trust it in critical joints and high-stress connections. The hex head design makes driving straightforward with standard tools, even in tight spaces, while the larger head diameter helps seating stability and torque control.

Practical use tips: pair these screws with compatible nuts or washers for secure assemblies, apply a light thread lubricant to reduce galling on stainless or hardened materials, and follow appropriate torque guidelines to avoid overtightening. They're well-suited for woodworking-to-metal connections, metal framing, and mounting brackets where a strong, durable fastener is required.
