Professional Applications & Engineering Value
This zinc-plated steel captive panel screw with press-fit nut addresses critical challenges in electronic enclosure assembly and industrial panel fastening. The quarter-turn mechanism significantly reduces installation time compared to traditional threaded fasteners, while the captive design prevents component loss during maintenance operations. Engineered with an 18-8 stainless steel retainer, this fastener maintains consistent clamping force even under vibration, eliminating the need for lock washers or thread-locking compounds. The system's precise dimensional specifications ensure perfect alignment with standard panel hole sizes, making it ideal for electronic enclosures, instrumentation panels, and industrial control cabinets where repeated access and reliability are paramount.
Specification Summary & Compliance
This 1/2" captive panel screw features inch system measurements with a 3/8" rounded head diameter and slotted drive style. The assembly includes a back press-fit nut and retainer, designed for inner panel hole diameters of 0.437" and outer panel holes of 0.25". Compatible with panel thicknesses from 0.09" to 0.11", the fastener system meets RoHS 3 (2015/863/EU) compliance standards and is REACH (EC 1907/2006) compliant, ensuring environmental regulatory adherence for global industrial applications.
