Product Description
Product Overview
This product is a Grade A cotter pin compliant with the national standard GB/T 91, manufactured from carbon steel and treated with galvanized surface. It is a classic anti-loosening fastener. After passing through a hole or slot, bending its two-strand tail can effectively prevent nuts, pins and other connectors from loosening, providing simple and reliable axial fixation.
Core Advantages
-
Reliable Anti-Loosening: The bent and spread tail can effectively lock components, resist vibration and impact, and prevent connection detachment.
-
Easy Installation: Simple structure, no special tools required; it can be easily installed and disassembled with pliers.
-
Economical and Durable: Low cost, the galvanized surface provides good rust protection, ensuring a long service life.
-
Strong Versatility: Complies with national standards, complete in specifications, good interchangeability, and widely used in various mechanical connections.
-
Customization Supported: Supports customization of various diameter and length specifications to meet special assembly needs.
Applicable Industries
-
Mechanical Equipment and Heavy Equipment: Axial anti-loosening and anti-fall locking of transmission parts and shaft parts in construction machinery, mining equipment, agricultural machinery, etc.
-
