SS303 Material Two-Lug Flange Nut with Tool-Free Manual Operation and Custom Mold One-Shot Forming

Ergonomically shaped dual lugs enable direct hand twisting, removing the need for additional wrenches. Perfect for frequent adjustment, repeated disassembly and cyclic reuse on construction and industrial sites.

Exclusive custom molds eliminate dimensional deviation; integrated forming avoids assembly gaps, with precise internal threads machined to tight tolerances. Threads mate smoothly with matching tie rods, free from jamming or thread stripping under frequent load cycles.

303 stainless steel features excellent free-cutting machinability and robust tensile strength, far outperforming carbon steel. It resists rust, concrete slurry erosion, moisture and salt spray, ideal for coastal construction, outdoor long-term exposure and wet working environments.

Monolithic cast construction has no split seams, maintaining stable clamping force even under vibration and heavy loads during concrete pouring or equipment fixation, not prone to loosening or deformation.

Stainless steel material withstands dozens of assembly cycles without corrosion or deformation, cutting long-term accessory replacement costs for formwork firms, rental companies and engineering contractors.
