quick release pin fasteners
The quick release pin fasteners is designed for fast, secure, and tool-free connection in industrial assemblies, jigs, molds, and marine fixtures. Featuring a ring handle for enhanced grip and operation, this pin also includes a 250mm anti-lost wire rope, helping prevent loss in dynamic or outdoor environments.
The quick release pin fasteners body and internal spring are made from SUS304 stainless steel, ensuring resistance to corrosion and wear. The precision-hardened SUS440 locking balls engage automatically during insertion, providing positive locking performance under repeated use.
Each pin is precision-machined with tight tolerances for consistent fit and function. This design is ideal for situations where frequent insertion and withdrawal are required while ensuring operator safety and efficiency.
