Professional Applications & Engineering Value
This 18-8 Stainless Steel captive panel screw delivers exceptional engineering value in industrial and electronic applications where reliability is paramount. The 1/4"-20 UNC coarse thread with Class 3A precision ensures rapid installation and maintains secure fastening even under vibration, making it ideal for electronic enclosures, control panels, and machinery guards. The knurled socket head combined with the 3/16" hex drive prevents cam-out during torque application, while the partial threading design provides controlled engagement depth. Manufactured from corrosion-resistant 18-8 stainless steel, this screw maintains integrity in environments exposed to moisture, chemicals, and temperature variations, solving common failure points in panel mounting systems.
Specification Summary & Compliance
This captive panel screw features precision 1/4"-20 UNC Class 3A threads with coarse thread spacing, manufactured to exacting dimensional tolerances (length tolerance: -0.03" to 0"). The fastener meets industry standards for thread fit and tensile strength (70,000 psi) and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global industrial and electronic applications.
