Finished Hex Jam Nut, Hot-Dip Galvanized (Inch)
Finished Hex Jam Nuts with a Hot-Dip Galvanized (HDG) coating are low-profile hex nuts designed for locking applications in harsh, outdoor, or corrosive environments. The HDG finish provides a thick, durable zinc layer that offers superior corrosion resistance, making these jam nuts suitable for infrastructure, structural steel, marine environments, and outdoor assemblies.
Because of their reduced height, these jam nuts are commonly paired with a standard nut to prevent loosening caused by vibration or movement. The hot-dip galvanized coating not only improves durability but also enhances thread protection, making them ideal for long-term installations exposed to weathering. These jam nuts deliver a reliable, cost-effective locking solution when strength and corrosion performance are critical.
