S-95966A686 M3 x 18 mm Captive Panel Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-term reliability in harsh environments.
• High tensile strength of 70,000 psi provides secure, vibration-resistant fastening for critical panel applications.
• Precise Class 6g thread fit guarantees smooth installation and consistent engagement in threaded panels.
• 2.5mm hex socket drive allows for high-torque application with standard tools, reducing slip and damage risks.
• Partially threaded shank design enables optimal clamping force and prevents over-threading in captive panel assemblies.
• Compliance with RoHS 3 and REACH ensures environmental safety and meets international regulatory standards.
• Coarse M3x0.5mm thread pitch facilitates quick assembly and reduces cross-threading in industrial settings.

Professional Applications & Engineering Value

Engineered for demanding industrial environments, this M3 captive panel screw in 18-8 stainless steel addresses common challenges like panel loosening under vibration and corrosion in electronic enclosures or machinery. The partially threaded design ensures the unthreaded shank bears against the panel, distributing load evenly and preventing material fatigue. With a 2.5mm hex drive, it allows for secure, high-torque installations without cam-out, while the Class 6g thread tolerance and coarse pitch enable rapid, reliable assembly in production lines. Ideal for panel mounting in telecommunications, automotive control units, and medical devices, it offers a corrosion-resistant solution that maintains integrity in humid or chemical-exposed settings, reducing maintenance costs and downtime.

Specification Summary & Compliance

This screw features an M3 thread size with 0.5mm coarse pitch and Class 6g thread fit per metric standards, ensuring dimensional accuracy for consistent performance. The length tolerance is -0.4mm to 0.4mm, and it is manufactured to comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for global industrial applications without hazardous substances.
