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
Detailed Product Features
1. 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 in precision instruments.
- Knurled Grip: Diamond or straight knurls (0.3-0.8mm pitch) enhance manual installation/removal in maintenance-intensive systems (ASME B94.6).
2. Advanced Material Science
| Material | Grade | Key Properties | Application Scope |
|---|---|---|---|
| Carbon Steel | 8.8, 10.9, 12.9 | Tensile strength ≤1,200 MPa | General machinery, structural |
| Stainless Steel | A2 (304), A4 (316) | Corrosion resistance (1,000h salt spray) | Marine, chemical processing |
| Brass | CW614N | Non-sparking, EMI shielding | Explosive environments, electronics |
| Aluminum | 6061-T6 | 55% weight reduction vs. steel | Aerospace, automotive |
Custom alloys (e.g., Inconel®/Titanium) available for extreme temp. (-200°C to +650°C).
3. Thread Compatibility
- Metric Threads: Fine (M4x0.5 - M100x4) or coarse pitch per ISO 898-2.
- Inch Threads: Unified UNC/UNF (e.g., #4-40 to 4"-16) compliant with ASME B1.1.
- Special Threads: ACME, trapezoidal, or self-locking deformable threads (DIN 980).
4. Surface Engineering
| Finish | Standard | Function |
|---|---|---|
| Zinc Plating | ISO 4042 (5-25µm) | Salt spray resistance (96-720h) |
| Black Oxide | MIL-DTL-13924 | Anti-galling & mild corrosion protection |
| Hot-Dip Galvanized | ASTM A153 | >1,000h industrial atmosphere life |
| Nickel Plating | AMS 2423 (15-50µm) | Wear resistance (500+ cycles Rc 50) |
5. Dimensional Flexibility
- Standard Sizes: M4 to M100 (metric) / #4 to 4" (imperial).
- Customization:
- Non-standard diameters/tapers (e.g., flanged designs for PCB mounting)
- Integrated locking features: Nylon inserts (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)
