Professional Applications & Engineering Value

This zinc-plated steel captive panel screw with quarter-turn functionality addresses critical challenges in industrial assembly where repeated access to internal components is required. The press-fit nut system eliminates traditional threading complications, providing immediate securement without specialized installation equipment. Engineered specifically for electronic enclosures, control panels, and equipment housings, the screw's 18-8 stainless steel retainer maintains consistent spring pressure that prevents back-out during operational vibration. The precise dimensional tolerances ensure reliable performance across the specified panel thickness range (0.07"-0.09"), while the captive panel screw design prevents component loss during maintenance cycles. This combination of features significantly reduces assembly time while enhancing the long-term service life of panel-mounted systems in demanding industrial environments.

Specification Summary & Compliance

This captive panel screw features inch system measurements with a 3/8" head diameter, 0.198" shank diameter, and 0.52" overall length. The press-fit nut accommodates inner panel hole diameters of 0.469" with installation thickness between 0.07"-0.09". The assembly includes front press-fit nut, retainer, and screw components. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring restricted substance compliance for global industrial applications.
