Our custom CNC wire form safety cotter pin, also named loop end spring lock pin and wire form cotter safety clip, is precision manufactured via automatic CNC wire bending equipment as a reliable wire formed quick release fastener. Made of solid 304 stainless steel wire, this stainless steel spring retaining clip features integrated loop end design for easy assembly and disassembly, stable elastic holding force and anti-rust performance after electrolytic polishing or passivation surface treatment. As a dedicated OEM manufacturer, we deliver fully customized wire form retaining clip products, accepting custom wire diameter, length, width and bending structure based on client technical drawings or physical samples. Each wire form safety cotter pin is processed with deburring to eliminate sharp bending edges, guaranteeing smooth surface and consistent elastic retention performance for long-term mechanical assembly use.
