Professional Applications & Engineering Value

This captive panel screw system addresses critical challenges in electronic enclosures, industrial control panels, and machinery access points where repeated maintenance is required. The zinc-plated steel construction combined with quarter-turn fastening technology provides reliable corrosion protection while enabling rapid service access without compromising security. The engineered press-fit nut design eliminates loose hardware concerns, maintaining perfect alignment between inner and outer panels. Particularly valuable in applications requiring frequent inspection or component replacement, this fastener system ensures consistent installation thickness control (0.09"-0.11") while accommodating minimal space between panels (0.01"). The inclusion of an 18-8 stainless steel retainer guarantees long-term performance in demanding environments where vibration resistance and durability are paramount.

Specification Summary & Compliance

This captive panel screw features precision dimensions including 3/8" head diameter, 0.198" shank diameter, and 0.54" length, engineered for optimal performance in panel assembly applications. The fastener system is designed to accommodate inner panel hole diameters of 0.469" and outer panel hole diameters of 0.25". Manufacturing compliance includes full adherence to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global industrial markets and electronic applications requiring restricted substance compliance.
