Meet the Hillman 1/2 in. x 1-3/4 in. Heat Treated Steel Hex Head Cap Screw, a high-strength fastener designed to lock joints in place with precision and reliability. This 50-pack boxed set brings the power of Grade 8 steel and a heat-treated finish to your toughest projects, from furniture builds to structural bracing.
-
Strength you can trust: Made from steel and heat-treated for enhanced toughness and load-bearing performance, so joints stay secure even under vibration and heavy use.
-
Precise geometry for fast, secure installs: 1/2 in. hex head diameter pairs with a 1-3/4 in. length and coarse threads to bite quickly into wood and lighter metals, reducing drive time and minimizing cross-threading.
-
Efficient, durable drive: Hex head design enables solid engagement with common wrenches and drivers, giving you steady torque control during installation.
-
Ready-for-project packaging: Comes in a boxed, 50-piece set, so you have ample fasteners on hand for building, repairing, or replenishing your hardware drawer.
-
Versatile, real-world applications: Ideal for attaching brackets, framing, furniture components, deck hardware, and other high-load connections where reliability matters.
Why choose heat-treated Grade 8 steel hex head cap screws?
These Hillman fasteners leverage heat-treated Grade 8 steel to deliver superior strength and fatigue resistance. The result is a fastener that maintains clamping force under stress, resists deformation, and provides long-lasting performance in demanding assemblies. While designed for heavy-duty use, the coarse thread and robust hex head also make installation straightforward, even in environments where fasteners may face vibrations or repetitive loads.
Use cases and best practices
- Deck and framing projects where reliable, high-torque connections are essential.
- Furniture builds and reinforcements that require solid, long-lasting joints.
- Brackets, supports, and metal-to-wood assemblies where a strong, secure screw is preferred over lighter fasteners.
- Repairs or replacements in existing structures that were originally assembled with similar Grade 8 fasteners.
Installation tips
- Align holes precisely and apply steady, even pressure while driving to prevent cross-threading.
- For hardwood or dense materials, consider pre-drilling a pilot hole to reduce resistance and ensure accurate alignment.
- Use washers when distributing load over a larger surface area or when joining softer materials to prevent pull-through.
- Pair with compatible nuts or threaded inserts as appropriate for your application to maintain secure, lasting connections.
