- Secure panel retention through partial threading that provides optimal grip without compromising installation speed
- Precise thread engagement with Class 2A fit ensuring consistent performance and reduced cross-threading risks
- Quick installation capability featuring coarse UNC threads for faster assembly in industrial applications
- Durable rounded head design with smooth texture that prevents damage to panel surfaces during operation
- Broad regulatory compliance meeting ASTM A581 specifications plus RoHS 3 and REACH environmental standards
- Versatile slotted drive allowing compatibility with standard tools for maintenance flexibility
Professional Applications & Engineering Value
This 18-8 stainless steel captive panel screw delivers exceptional value in industrial settings where panel retention and corrosion resistance are critical. The 6-32 UNC coarse thread configuration enables rapid installation while maintaining secure fastening, particularly valuable in maintenance-intensive equipment. The partially threaded design creates a captive mechanism that prevents complete screw removal, eliminating lost hardware in field service scenarios. Manufactured to ASTM A581 standards, these screws provide consistent mechanical properties for electrical enclosures, control panels, and machinery guards where vibration resistance and durability are paramount. The slotted drive with rounded head profile ensures compatibility with standard tools while protecting panel finishes during repeated access cycles.
Specification Summary & Compliance
This captive panel screw maintains Class 2A thread fit per UNC standards with precise dimensional control. The 6-32 thread size with coarse spacing and partial threading (7/32" thread length on 1" overall length) ensures optimal performance. Manufacturing complies with ASTM A581 specifications for quality assurance. Environmental compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, making these screws suitable for global industrial applications with strict material restrictions.
