I. Product Positioning

Round nuts (commonly referred to as circular nuts) utilize internal threads to mate with external threads on shaft ends. When paired with lock washers or cotter pins, they deliver axial positioning and anti-loosening locking for components mounted on shafts. These nuts are widely employed in shaft drive systems across machine tools, motors, and construction machinery.

II. Structure & Anti-Loosening Mechanism
  • Core Structure: Features a circular outer profile (with 4 or 6 machinable locking slots) and internal threads that align with shaft-end thread specifications.
  • Anti-Loosening Principle:
    Once tightened, lock washer tabs engage with the locking slots (or cotter pins pass through the slots and shaft pin holes), eliminating rotational movement and preventing loosening under vibration or impact.
III. Materials & Surface Treatments
Material Type Performance Highlights Surface Treatment Application Scenarios
Carbon Steel (45#, 40Cr) High strength; superior impact resistance after quenching. Zinc plating (corrosion resistance), black oxide (wear resistance). Heavy-duty equipment (rolling mills, excavators).
Stainless Steel (304, 316) Corrosion resistance; lightweight design. Mirror polishing, passivation. Food machinery, marine engineering.
Alloy Structural Steel High-temperature resistance (≤400℃); excellent fatigue resistance. Dacromet coating (extreme corrosion protection). Aero-engines, high-temperature furnaces.
IV. Typical Applications
  1. Precision Machinery: Secures bearing inner rings on machine tool spindles (e.g., machining centers, grinders) to ensure rotational accuracy.
  2. Power Equipment: Fixes couplings and pulleys on motor shafts, guaranteeing stable torque transmission.
  3. Construction Machinery: Used on excavator bucket pins and loader drive shafts, withstanding impact and vibration without loosening.
  4. Automotive & Vehicle Manufacturing: Secures axle hubs and transmission input shafts, enabling maintenance-free anti-loosening and enhancing system reliability.
V. Specifications & Standards
  • Thread Sizes: Ranges from M10 to M100 (metric threads, precisely matching shaft-end threads).
  • Locking Slot Design: Available in 4-slot or 6-slot configurations (matching lock washer tab counts; custom slot designs are optional).
  • Standards Compliance: Complies with GB/T 812 (China), DIN 981 (Germany), and IFI 167 (USA), facilitating global procurement.
VI. Core Competitive Advantages

Reliable Anti-Loosening: Mechanical locking (via washers or cotter pins) outperforms nylon nuts in high-vibration environments.
Precise Positioning: Works in tandem with shaft shoulders to secure bearings, gears, and other components, simplifying shaft system design.
Standardization & Compatibility: Adheres to multinational standards, ensuring universal compatibility across global equipment and reducing costs.
Customization Flexibility: Supports special materials (e.g., high-temperature alloys), non-standard slots, and tailored surface finishes.
