Product Description:


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



Key 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

Tested to:

  • 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)
