When structural integrity is non-negotiable, the choice of fasteners becomes as critical as the design itself. Our ASTM A194 Gr.2H Heavy Nut represents a trusted solution for engineers and contractors who demand consistent performance under extreme loads. Manufactured in strict accordance with ASME B1.1 thread standards, this 2‑inch heavy hex nut features a 6 UNC coarse thread profile that ensures rapid, secure assembly even in field conditions where debris or minor thread damage might otherwise cause delays. The heavy hex geometry—with its larger bearing surface and thicker section—distributes clamping force evenly, reducing the risk of embedment or loosening under vibration, a common concern in dynamic environments such as bridges and tunnel supports.
As a China manufacturer with decades of experience in high‑strength fasteners, we produce this nut from premium ASTM A194 Gr.2H material, a quenched and tempered carbon steel that delivers minimum tensile properties well above standard carbon steel grades. This material is specifically selected for service at elevated temperatures and in high‑pressure bolting applications, making it a preferred choice for structural engineers worldwide. The black oxide surface treatment is not merely cosmetic; it provides a controlled, micro‑porous layer that retains lubricants for consistent torque‑tension relationships during installation, while offering robust resistance against atmospheric corrosion in both indoor and outdoor exposures.
In practice, this heavy nut is indispensable for the assembly of building structures, where it secures column splices and beam connections; for scaffolding systems, where repeated load cycling demands reliable locking; and for bridge and tunnel construction, where long‑term durability directly impacts public safety. Its compatibility with matching ASTM A325 or A490 structural bolts ensures a fully code‑compliant connection. Whether you are erecting a high‑rise in coastal regions, retrofitting an aging overpass, or anchoring heavy industrial equipment, this 2” heavy hex nut delivers the margin of safety that rigorous projects require. We back every batch with full material traceability and mechanical test reports, reaffirming our commitment as a China manufacturer that prioritizes quality over volume. Choose this heavy nut for your next project—and fasten with confidence, knowing that reliability is engineered into every thread.
