Meet the Hillman 1/2 in. D x 5 in. L Hot Dipped Galvanized Steel Hex Bolt — a tough, weather-ready fastener designed to solve outdoor assembly challenges with confidence. Built from sturdy steel and finished with a durable hot-dip galvanization, this hex bolt resists rust and corrosion in damp environments, making it a reliable choice for exterior projects and long-term installations.
Why this hex bolt stands out
-
Corrosion-ready finish: Hot dipped galvanized coating provides a robust barrier against moisture, salt, and humidity, extending service life for decks, fences, sheds, and outdoor furniture.
-
Solid, general-purpose strength: Grade 2 steel delivers dependable performance for everyday construction and repair tasks without the higher cost of heavier-duty fasteners.
-
Exact sizing for quick matching: 1/2 inch diameter with a 5 inch length fits a wide range of lumber and metal applications; coarse threads ensure strong bite in wood and easy driving with standard tools.
-
Ready-to-use packaging: Comes in a boxed set of 25 bolts, ideal for stocking up on common fasteners for ongoing projects or multi-item builds.
-
Versatile head design: Hex head allows easy installation with common wrenches or sockets, enabling firm clamping and secure joint formation.
Ideal uses and practical applications
- Outdoor framing and structural projects such as decks, pergolas, and garden sheds where exposure to the elements is a factor.
- Wood-to-metal connections in fencing, railing systems, and gate hardware where corrosion resistance is critical.
- General repairs to furniture, shelving supports, and DIY installations that require a reliable, corrosion-resistant fastener.
- Replacement hardware for maintenance kits or construction kits that rely on standard 1/2" x 5" hex bolts.
Tips for best results
- Pair with appropriate nuts and washers for a complete connection; washers help distribute clamping force on softer wood and prevent pull-through.
- Pre-drill pilot holes in dense or knotty wood to reduce splitting and ease driving with a standard wrench or driver.
- For outdoor, load-bearing applications, assess whether Grade 2 bolts meet your structural requirements or if a higher-grade fastener is warranted.
- Store with the box closed to keep count accurate and protect against rust on any exposed threads prior to use.
