S-95966A687 M3 x 20 mm Captive Panel Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring longevity in humid or demanding industrial environments.
• High tensile strength of 70,000 psi provides reliable load-bearing capacity and prevents fastener failure under stress.
• Secure, tamper-resistant fastening via the hex socket drive (2.5mm), allowing precise torque application and reducing tool slippage.
• Optimized panel retention with partial threading and Class 6g thread fit, minimizing cross-threading and simplifying alignment during assembly.
• Consistent dimensional accuracy with a length tolerance of ±0.4mm, ensuring uniform performance and interchangeability in high-volume applications.
• Compliance with RoHS 3 and REACH regulations guarantees safe use in electronics and other sensitive industries without hazardous substances.
• Coarse thread pitch (0.5mm) enables quicker installation and enhanced vibration resistance in panel fastening systems.

Professional Applications & Engineering Value

This M3 captive panel screw is engineered to address common challenges in electronic enclosures, machinery panels, and industrial equipment where secure, repeated access is critical. The 18-8 stainless steel material offers excellent resistance to oxidation and chemical exposure, reducing maintenance costs in harsh environments. With a partial threaded design and Class 6g thread fit, it ensures precise engagement without binding, speeding up assembly lines and minimizing rework. The hex socket drive allows for high-torque installation, making it ideal for automated or manual setups in panel fastener applications, while the coarse metric thread enhances durability against loosening under dynamic loads.

Specification Summary & Compliance

This screw adheres to Metric system standards with a thread size of M3, pitch of 0.5mm (coarse spacing), and Class 6g thread fit for consistent dimensional precision. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and suitability for global industrial markets.
