Top Split Pin Manufacturer for Custom Non-Standard Fasteners

A split pin, also known as a cotter pin, is a simple yet critical fastener used to secure components on shafts, clevis pins, and pivot joints. As a specialized Split Pin Manufacturer, we understand that the performance of a split pin depends on precise leg geometry, material spring properties, and consistent surface quality. Our production integrates forging, cold heading, CNC machining, and stamping, allowing us to produce both standard-style and custom non-standard split pins. For international customers, this means one partner capable of managing material selection, forming, secondary machining, and surface treatment. We operate 8 forging machines including 630T and 300T, 10 multi-station cold heading forming machines, over 100 CNC lathes, 50 CNC machining centers, 20 turning-milling composite machines, and 10 centering machines. This equipment mix supports flexible batch sizes, from trial orders to recurring supply programs. For split pins, we focus on consistent leg spread, smooth edges, and reliable insertion and locking behavior. We also provide various surface treatments to suit indoor, outdoor, or high-moisture environments, helping customers extend service life and reduce field failures. Our team collaborates with buyers worldwide to align specifications, packaging, and inspection criteria, ensuring every shipment meets the agreed requirements.
