Mechanical Properties
Core Functions
Load Distribution:
The flange face replaces a flat washer, increasing contact area and reducing surface pressure to protect surfaces of connected parts.
Mechanical Locking:
The toothed flange face embeds into the substrate upon tightening, resisting loosening from vibration/impact via friction.
Simplified assembly:
Integrated nut washer design eliminates the need for additional flat washers, improving assembly efficiency.
Positioning & Anti-rotation:
The flange face aids in positioning, reducing assembly alignment.
Core Features
Integrated Structure:
Hex flange in one piece, available in two types: toothed (strong locking) and smooth (protects soft/coat surfaces).
01
Stronger Load Bearing:
30% larger support area than standard hex nuts, suitable for heavy loads and thin/soft material connections. Reliable Locked surface engagement forms a mechanical lock, offering superior vibration resistance compared to standard nuts.
02
Materials & Grades:
Carbon steel (Grade 8/10/12), Stainless steel (A2-70/A4-80), suitable for general and corrosive environments.
03
Specifications:
Metric coarse/fine thread, common sizes M5–4, Class A (≤M16), Class B (>M16).
04
Efficient Assembly:
Washer-free, single-step tightening, suitable for automated production lines.
05
Major Industry Application Scenarios
Automotive Manufacturing:
Chassis, suspension, engine, transmission, braking systems (high vibration heavy load). Construction Machinery: Excavators, cranes, loaders, hydraulic equipment heavy load frequent vibration).
Rail Transit:
Bogies, car bodies, track fasteners (long-term dynamic loads).
General Machinery:
Pumps, valves, gearboxes, machine tools, motors, fans (structural fastening locking).
Sheet Metal / Thin Plate Connection:
Cabinets, enclosures, elevators, home appliances (prevents indentation locking).
Outdoor / infrastructure:
Photovoltaic brackets, bridge railings, wind power equipment (weather-resistant wind vibration resistance).
Electronics / Home Appliances:
Enclosures, motors, compressors (compact space + anti-loosening).
