S-94188A140 Length 1.1" Captive Panel Screws

Key Features & Benefits at a Glance

• Exceptional temperature resistance from -40° to 190°F for reliable performance in harsh industrial environments
• Lightweight and corrosion-resistant Acetal Plastic construction reduces panel weight and eliminates rust in electrical or sensitive applications
• Quick quarter-turn captive mechanism enables fast panel access and secure retention without loose parts
• Integrated rivet-mount design provides permanent nut installation without requiring rear panel access
• Precision dimensional compatibility with 0.4" to 0.45" panel thicknesses ensures perfect fit and vibration resistance
• Slotted drive head allows easy installation with standard tools while maintaining clean aesthetics
• Full regulatory compliance with RoHS 3 and REACH standards for global industrial acceptance

Professional Applications & Engineering Value

Engineered for electronic enclosures, instrumentation panels, and access covers, this Acetal Plastic captive panel screw kit solves critical assembly challenges. The quarter-turn fastener system with integrated rivet-mount nut eliminates traditional threading issues and provides permanent mounting in thin panels where backside access is limited. The black Acetal Plastic construction offers excellent electrical insulation properties while resisting chemicals and environmental degradation. With precise dimensional control for 0.438" inner and 0.39" outer panel holes, this solution prevents panel warping and maintains consistent clamping force across the specified temperature range from -40° to 190°F, making it ideal for outdoor equipment, automotive components, and industrial control systems where thermal cycling occurs.
