Professional Applications & Engineering Value
This 18-8 Stainless Steel captive panel screw addresses critical challenges in electronic enclosures, machinery panels, and industrial equipment where repeated access is required. The knurled head design combined with 3/16" hex drive provides positive grip during installation, eliminating tool slippage that can damage sensitive panel surfaces. The 1/4"-20 UNC Class 3A threads ensure precise fitment in threaded inserts and captive hardware, maintaining alignment while resisting vibration-induced loosening. The partially threaded shank allows the screw to remain captured in panel assemblies during maintenance cycles, preventing loss and reducing reassembly time. These engineering features make it ideal for aerospace, telecommunications, and industrial control systems where reliability and serviceability are paramount.
Specification Summary & Compliance
Manufactured to precise inch system dimensions with length tolerance of -0.03" to 0". Features 1/4"-20 UNC coarse threads with Class 3A fit for superior thread engagement. The screw meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements, ensuring adherence to international environmental and safety standards for industrial components.
