The QL8C62 Kee'd threaded receptacle is a precision seven-piece self-locking insert assembly engineered for fastening systems requiring positive locking capability. The assembly features a 303 stainless steel threaded barrel with 1/2-13 UNC internal mounting threads and .1640-32 quad-lead cam groove for stud engagement. Internal components include dual spring-loaded cam assemblies, nested 17-7 PH stainless steel compression springs, and four 304 stainless steel Kee retention tabs. This design provides self-locking capability through the Kee tab mechanism while maintaining rapid quarter-turn installation and removal. The receptacle is secured with 1/2-13 UNC threads for installation into tapped holes or mounting plates.
📏 Installation Guide: The QL8C62 Kee'd receptacle requires a tapped 1/2-13 UNC hole for installation. The self-locking Kee tabs engage automatically during stud rotation, providing positive locking without additional hardware. Ensure proper thread engagement depth and torque specification for secure mounting. This receptacle is ideal for applications requiring positive locking to prevent inadvertent opening in high-vibration or safety-critical installations.
