Product Introduction

Our Type B cotter pins, also known as R-shaped spring retaining pins, are standard hardware fasteners widely used for mechanical positioning, connection and anti-loosening assembly. Manufactured from premium carbon steel and treated with galvanized surface finish, these wave-shaped curved pins feature excellent rust resistance, wear resistance and sturdy structural strength, effectively avoiding corrosion during long-term use in various working environments.

The special curved loop design delivers reliable locking performance. Once inserted into the pin hole, they stay firmly fixed and will not slip off easily, which can securely lock shafts, bolts, machinery components, agricultural equipment, vehicle parts and engineering fittings to prevent accidental disassembly and falling off.

We boast comprehensive specifications covering diverse nominal diameters (1mm/1.2mm/1.5mm/1.6mm/1.8mm/2mm) and multiple lengths ranging from 18mm to 33mm, totally matching 54 sizes to satisfy different machinery, engineering and assembly scenarios. Sufficient spot inventory supports bulk wholesale orders with fast delivery. Custom sizes and surface treatments are available to meet personalized engineering procurement demands.

Precision bending processing ensures smooth surface without burrs, convenient for quick manual installation and removal. Ideal for machinery maintenance, agricultural machinery, automobile fittings, construction engineering, trolley and hardware assembly applications.
