Meet the Hillman 3/4-10 in. D x 8 in. L hex head cap screw — a purpose-built fastener engineered for strength, durability, and dependable holding power in workshop projects and professional installations. With a heat-treated zinc finish and robust steel construction, this screw is designed to resist wear, maintain torque, and resist corrosion in many indoor and sheltered outdoor environments.
The 3/4-10 size denotes a large-diameter screw with 10 threads per inch, enabling quick assembly and a strong grip in wood and softer metals. Its blunt point makes it easier to drive into pre-drilled holes or through panels without splitting delicate material, while the coarse thread bites firmly for reliable pullout resistance.
Ideal for:
- Wood framing and deck construction where a longer through-fastener is needed
- Machinery mounting, equipment enclosures, and heavy-duty brackets that require deep engagement
- Pre-drilled through-holes in soft metals or composite materials

How this screw stands apart:
- Heat-treated zinc finish combines increased hardness with corrosion resistance, reducing wear from vibration and repeated assembly/disassembly
- Hex head accepts standard wrenches or impact drivers, delivering high-torque security in tight spaces
- Coarse threads provide rapid bite in wood and soft metals, making it ideal for fast, repeatable projects
- Long 8-inch length enables through-bolting or deep engagement where shorter screws would fall short
- Blunt point minimizes material splitting when driven into pre-drilled holes or through panels
Practical tips for best results:
- Pair with a compatible nut and washer for a secure, vibration-resistant connection
- Use a pre-drilled pilot hole to maintain material integrity, especially in hardwoods
- Check alignment and ensure the screw length provides sufficient engagement without protruding on the opposite side
