Wing Nut

The STAINLESS STEEL WING NUT is a tool-free hand-operated fastener designed for frequent assembly and disassembly in humid, coastal or corrosive working environments. It consists of a central threaded barrel and two large symmetrical flat grip wings, allowing direct finger tightening and loosening without spanners, sockets or power tools.

Manufactured from premium 304 stainless steel, this wing nut delivers outstanding tensile strength and inherent anti-rust, acid and salt fog resistance. The surface undergoes polishing and passivation treatment to form a dense inert protective film, effectively resisting rainwater, sea mist and atmospheric oxidation, eliminating rust failure issues of carbon steel wing nuts under long-term outdoor exposure.

The widened flat wing structure provides a larger non-slip gripping surface for bare hands, boosting torque control and operation comfort during repeated fastening cycles. Precisely rolled internal threads match standard metric bolts seamlessly, maintaining stable clamping force without thread deformation or slipping after multiple disassembly operations.

Stainless steel wing nuts are widely applied to outdoor solar equipment fittings, marine pipeline hardware, outdoor lamp brackets, medical instrument casings, laboratory test jigs and all quick-release assemblies exposed to moisture or mild corrosive media. Its dual advantages of tool-free operation and permanent corrosion resistance make it the preferred fastener for special environment adjustable components.

We provide full OEM and ODM custom manufacturing services and support tailor-made production based on customer technical drawings, physical samples and custom wing dimension requirements. Custom thread sizes, wing width, barrel height and dedicated export packaging options are available to meet marine, medical and outdoor equipment engineering project demands. Private laser marking and custom brand printing services are also supported for stainless steel hardware distributors, medical equipment manufacturers and marine engineering contractors.

Each STAINLESS STEEL WING NUT is produced under strict stainless steel fastener quality control standards. All finished wing nuts pass comprehensive dimensional inspection, thread precision test, wing bending fatigue sampling test and surface salt spray anti-corrosion performance verification before shipment, to guarantee accurate thread tolerance, stable wing structural strength and uniform long-term rust-proof finish for every production batch.
