Bronze Hex Nut for Multi-Bolt Raised Manholes (Model #2421)
The Model #2421 is a heavy-duty, marine-grade replacement hex nut precision-machined for the rugged perimeter securement requirements of multi-bolt raised manholes. Fabricated from premium cast marine bronze, this fastener interfaces seamlessly with steel or stainless steel flange bolts. The natural low-friction properties of the bronze alloy isolate the threading, absorbing intense compression forces while ensuring smooth, predictable manual breakdown and assembly cycles on open working decks.
Key Features
- Sacrificial Anti-Galling Threading: Non-ferrous bronze construction inherently eliminates the risk of thread binding and friction-welding when torque is applied against steel or stainless steel studs.
- Corrosion-Resistant Performance: Exceptional resistance to atmospheric saltwater pitting, oxidation, and mineral scale build-up without requiring protective zinc coatings or paint.
- Thickened Hex Flank Geometry: Heavy-duty structural cross-section is explicitly designed to maximize wrench engagement and resist corner rounding when subjected to heavy field impacts or high-torque pneumatic wrenches.
