• Integrated clip-on nut system eliminates loose hardware and simplifies installation in tight spaces with minimum 0.026" panel spacing
• 18-8 stainless steel retainer maintains consistent performance and prevents material degradation through repeated cycling
• Precise dimensional compatibility with 0.312" mounting holes ensures proper alignment and secure panel retention
• Phillips drive design offers familiar, tool-friendly installation while preventing over-torque damage to panels
• Comprehensive environmental compliance meets RoHS 3 and REACH standards for global manufacturing applications

Professional Applications & Engineering Value

Engineered for electronic enclosures, control panels, and access covers, these quarter-turn captive panel screws solve critical assembly challenges in industrial settings. The zinc-plated steel construction combined with the 18-8 stainless steel retainer creates a durable fastening system that withstands repeated access cycles without performance degradation. The clip-on nut design eliminates the need for threaded inserts in thin panels (0.02"-0.194" thickness range), while the 0.54" length accommodates total panel thickness up to 0.25". This captive panel screw solution prevents lost hardware in field service applications and maintains consistent clamping force through the Phillips drive system, making it ideal for maintenance-intensive equipment where quick access is essential.

Specification Summary & Compliance

This captive panel screw assembly features inch system measurements with a 3/8" head diameter, 0.198" shank diameter, and 0.54" overall length. The fastener system is designed for 0.312" mounting holes and accommodates panel thickness from 0.02" to 0.194" with total assembly thickness of 0.23" to 0.25". Manufacturing and material compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring suitability for global industrial applications requiring restricted substance compliance.
