DIN314 Stainless Steel Wing Nut-Butterfly Nut-Hand Twist Tighten Hardware Nuts Butterfly Wing-Nut

description

1. Performance & Material Properties
   • Premium 304 Stainless Steel Construction – Molded from AISI 304 austenitic stainless alloy for exceptional toughness (tensile ≈515 MPa) and elongation (>40 %), with a passive chromium-oxide surface that resists oxidation, pitting and crevice corrosion in indoor, outdoor and mildly aggressive environments.
   • Precision-Rolled Coarse Threads – Standard UNC-series threads (e.g. ¼-20, 5/16-18) are cold-rolled to increase root strength, deliver smooth engagement and minimize stripping or galling during repeated hand-twist operations.
   • Ergonomic Wing-Shape Design – Generous “butterfly” wings provide ample torque leverage for secure clamping without tools; smooth radiused edges enhance user comfort and reduce finger fatigue.
   • Temperature & Chemical Resistance – Remains dimensionally stable from –50 °C to +400 °C and tolerates common cleaning agents, detergents and mildly acidic or alkaline solutions without surface degradation.
2. Detailed Application Range
   • Home Maintenance & DIY – Ideal for securing jigs, fixtures, shelving brackets, picture frames, camera mounts and garden or patio hardware where frequent adjustments are required.
   • Professional Engineering & Machinery – Used as quick-release fasteners on access panels, machine guards, control boxes, inspection hatches and test fixtures in manufacturing, automation and robotics.
   • Furniture & Exhibit Assembly – Perfect for flat-pack furniture, display stands, trade-show booths and modular exhibition walls where tool-free assembly and teardown save time.
   • Marine, Automotive & Outdoor Equipment – Corrosion-resistant wing nuts fasten boat hardware, railings, trailer accessories, lighting trusses and outdoor signage, ensuring reliable performance even under vibration and exposure to salt spray.
3. Effortless Operation & Adjustability
   • Tool-Free Hand Tightening – Large butterfly wings deliver >1.5 Nm of tightening torque by hand, eliminating the need for wrenches or drivers; ideal for field adjustments and rapid assembly/disassembly.
   • Quick-Release Feature – Smoothly backs off with a few turns for instant loosening; threads remain protected from deformation or cross-threading, enabling repeatable clamping cycles.
   • Universal Compatibility – Offered in all common inch and metric sizes (UNC, UNF, M6–M12) to mate with standard machine screws, studs and threaded rods; fits both coarse and fine pitch applications.
   • Low-Profile Head Options – Choice of standard wing height or slim “low-profile” wing nut styles for applications with limited clearance around the fastener.
4. Superior Quality & Long-Term Reliability
   • ISO 9001 & ASTM A194 Certification – Manufactured in ISO-certified facilities to meet ASTM A194 grades for stainless steel nuts, guaranteeing dimensional accuracy (±0.1 mm) and consistent mechanical properties.
   • Rigorous Corrosion & Mechanical Testing – Each batch undergoes salt-spray testing (ASTM B117 ≥720 h), thread-profile inspections and hand-torque validation to ensure long-term performance under cyclic loads and environmental stress.
   • RoHS & REACH Compliance – Free of hexavalent chromium and other hazardous substances; fully recyclable stainless steel construction supports sustainable design and regulatory adherence.
   • Full Traceability & Packaging – Lot-coded from melt to finished part with material certificates; available in bulk packs or compartmented kits (50–500 pcs) for efficient inventory management and on-site convenience.
