Hex Bolts Steel HDG 1/2-13 X 4 are high-strength fasteners designed for outdoor and heavy-duty applications. These hot-dip galvanized hex bolts deliver reliable performance where corrosion resistance is essential. Constructed from solid steel and finished with a robust hot-dip galvanization (HDG), they resist rust and corrosion in wet or outdoor environments. Size and thread: 1/2 inch diameter with 13 threads per inch (1/2-13 UNC) Length: 4 inches Material and finish: Steel with hot-dip galvanized coating for long-lasting corrosion resistance Head type: Hex bolt for easy installation with a standard wrench or socket Applications: Ideal for outdoor structures, fences, decks, machinery, and other metal-to-metal or wood-to-metal connections Compatibility: Works with standard hex nuts and washers; use with appropriate pilot holes and pilot sizes Why choose HDG hex bolts? The galvanizing process provides an extra barrier against moisture, chemicals, and salt spray, extending the life of fasteners in challenging environments. For best results, pair with compatible nuts and washers and follow standard torque guidelines to avoid over-tightening. Add Hex Bolts Steel HDG 1/2-13 X 4 to your hardware stash for reliable, weather-resistant performance on every project.
