Round Nuts: Precision Locking Solutions for Demanding Applications
Round nuts are specialized fasteners engineered with a cylindrical outer profile and internal threads, designed to deliver superior locking performance in high-vibration or dynamic-load environments. Unlike standard hex nuts, their circular shape allows installation in confined spaces and enables tool engagement from multiple angles.
Key Features & Advantages
- 360° Tool Access: External grooves/spanner flats accommodate hook wrenches, pins, or C-spanners for secure tightening in restricted areas.
- Vibration Resistance: Locking variants (e.g., nylon inserts, flange designs) prevent self-loosening under shock loads (compliant with DIN 981, ASME B18.13).
- Material Versatility: Available in carbon steel (Grade 8.8/10.9), stainless steel (A2/A4), and brass, with optional zinc plating or dacromet coating for corrosion protection.
- High Load Distribution: Full-body design minimizes stress concentration, enhancing joint integrity in pulleys, bearings, and rotating shafts.
Typical Applications
Bearing retention in industrial machinery
Adjusting mechanisms on valves and actuators
Securing components in automotive transmissions
Mounting fixtures for robotics and aerospace assemblies
Custom Options
- Sizes: M3 to M100 (metric) / #4 to 4" (imperial)
- Locking Types: Nylon insert, all-metal lock, serrated flange
- Surface Treatments: Passivation, hot-dip galvanizing, Xylan® coating
Technical Specifications
Precision-Engineered Profile
- Circular Body: Optimized for confined spaces (e.g., bearing housings, valve stems) where hexagonal tools cannot rotate.
- Surface Variants: Smooth finish for low-friction rotation or knurled grip (0.3-0.8mm pitch) for enhanced manual installation/removal (ASME B94.6).

- Customization: Non-standard diameters/tapers (e.g., flanged designs for PCB mounting) or integrated locking features (Locking Torque ≥60% of tightening torque per DIN 985).
Performance Validation
- Vibration Resistance: DIN 65151 (10 million cycles @ 50Hz)
- Torque-to-Yield: Exceeds ISO 898-1 requirements by 15%
- Corrosion: ASTM B117 (1,000h neutral salt spray)
