S-95966A221 6-32 x 1/2" Captive Panel Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments and extended service life.
• Secure and non-slip installation thanks to the knurled head texture, providing enhanced grip during manual or tool-assisted fastening.
• High-strength performance with a 70,000 psi tensile strength, ensuring reliable clamping force and resistance to vibration loosening in panel assemblies.
• Precision thread engagement from the Class 3A fit and 6-32 UNC coarse thread, enabling quick assembly and reduced cross-threading risks.
• Optimized for captive panel applications with a partially threaded design, preventing the screw from falling out during maintenance or disassembly.
• Easy drive compatibility using a standard 7/64" hex key, facilitating efficient installation and removal in confined spaces.
• Environmental compliance assurance meeting RoHS 3 and REACH standards, making it suitable for global industrial and electronic markets.

Professional Applications & Engineering Value

This 18-8 Stainless Steel Captive Panel Screw is engineered to address common challenges in electronic enclosures, industrial control panels, and communication equipment. The knurled hex socket head provides a secure grip that prevents slippage during repeated access, while the 6-32 UNC coarse threading with a Class 3A fit ensures precise, durable connections that resist vibration and thermal cycling. Its partially threaded shank and captive design eliminate the risk of lost hardware during servicing, reducing downtime in maintenance-intensive environments. The robust 70,000 psi tensile strength and corrosion-resistant material make it a reliable choice for demanding applications where long-term performance and regulatory compliance are critical.
