Professional Applications & Engineering Value

This quarter turn captive panel screw system addresses critical challenges in electronic enclosures and industrial panel assemblies where space constraints and frequent access requirements exist. The Acetal plastic material delivers exceptional dimensional stability and chemical resistance while preventing galvanic corrosion when mating with dissimilar metals. The innovative clip-on nut design securely fastens between panels as thin as 0.03" while accommodating total thickness up to 0.29", solving vibration-induced loosening problems common in mobile equipment and machinery. The 1/4" shank diameter and 5/8" head provide optimal torque transmission without damaging delicate panel materials, making these captive panel screws ideal for telecommunications, automotive, and aerospace applications requiring repeated service access.

Specification Summary & Compliance

This fastener system features precision-engineered dimensions including 0.25" shank diameter, 0.9" length, and 0.512" hole diameter compatibility. The assembly accommodates panel thickness from 0.03" to 0.09" (inner) and 0.24" to 0.29" (total) with minimum 0.04" space between panels. Manufactured from high-grade Acetal plastic in black finish, the system is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global industrial markets and sensitive electronic applications.
