Professional Applications & Engineering Value

This captive panel screw with quarter-turn mechanism solves critical challenges in electronic enclosures and industrial chassis by combining zinc-plated steel corrosion resistance with a clip-on nut that prevents dislodgement during vibration. The 18-8 stainless steel retainer maintains consistent clamping force, eliminating panel rattling in dynamic environments. Engineers benefit from precise compatibility with 0.312" holes and panel thicknesses up to 0.174", streamlining high-volume assembly while reducing warranty issues from fastener failure. Its slotted drive supports both manual and automated installation, making it a versatile choice for industrial fasteners in telecom, automotive, and control panel applications where reliability and regulatory compliance are paramount.

Specification Summary & Compliance

This fastener adheres to inch system dimensions, including 3/8" head diameter and 0.52" length, with precise fit for 0.312" hole diameters. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring restriction of hazardous substances. The clip-on nut and retainer are engineered for consistent performance across specified panel thickness ranges (inner: 0.02"–0.174", total: 0.21"–0.23"), supporting reliable use in standardized assembly processes.
