- High-strength, 3/4" diameter by 4" length Corten (weathering steel) T-head bolt with a heavy hex nut designed primarily for underground utility, waterworks, and buried mechanical joint pipe connections.
- T-Head (Teardrop shape), optimized to lock into mechanical joint flanges to prevent the bolt from spinning during installation.
- Corten (High-Strength, Low-Alloy Steel), which naturally forms a protective, corrosion-resistant oxide patina when buried or exposed to moisture.
- Securing mechanical joints (MJ) on iron pipes, valves, hydrants, and fittings.
- Ideal for underground environments where standard zinc-plated bolts would rapidly corrode and fail.
