This is Construction Formwork Wing Nut, a core supporting fastener for formwork systems in concrete pouring construction. It is used with through-wall tie bolts to lock and fix formwork panels on both sides, accurately control wall thickness, resist the lateral pressure generated during concrete pouring, and prevent form expansion and slurry leakage. It is a standard supporting hardware for formwork systems in housing construction, bridges, tunnels and other projects.

Application Concrete pouring projects such as shear walls, beams and columns in housing construction, bridge piers, tunnel lining, compatible with various through-wall screws and formwork systems

1. High Load-bearing Strength: Integral casting of malleable cast iron, excellent tensile and impact resistance, can withstand large lateral pressure to ensure construction safety.
2. Efficient Construction: Wing-shaped design requires no tools, can be quickly tightened manually, greatly improving the efficiency of formwork erection and removal, shortening the construction period.
3. Long-term Corrosion Resistance: Uniform and dense galvanized layer, effectively isolate water vapor, acid and alkali corrosion, extend product service life, reduce maintenance cost.
4. Strong Versatility: Compatible with industry-standard through-wall screws and various formwork systems, widely used in various construction scenarios.
5. High Cost Performance: Reusable for multiple cycles, greatly reducing engineering consumable cost, a cost-effective fastener for formwork engineering.
