S-90548A171 M5 x 8.8 mm Captive Panel Screws

Key Features & Benefits at a Glance

• Secure hand-tightening without tools thanks to the knurled thumb head and Phillips No. 2 drive for quick assembly and disassembly in tight spaces.
• Enhanced grip and corrosion resistance from the black powder-coated aluminum head, ensuring reliable performance in demanding industrial environments.
• Superior strength and durability with a 400 series stainless steel screw body, providing excellent resistance to wear and environmental factors.
• Optimized for standard panel thicknesses (1.6mm to 2.5mm) with a 6.4mm hole diameter, ensuring a secure fit and reducing installation errors.
• Reliable coarse threading (M5 x 0.8mm) for faster engagement and reduced cross-threading risks in right-hand thread applications.
• Compliance with major environmental standards including RoHS 3 and REACH, making it safe for use in global electronics and industrial sectors.
• Consistent dimensional accuracy with a 13mm head diameter and 8.8mm length for repeatable performance in captive panel assemblies.

Professional Applications & Engineering Value

This M5 thumb screw is engineered to address common challenges in panel mounting for electronics, machinery, and enclosures. The combination of a powder-coated aluminum head and 400 series stainless steel body ensures lightweight handling without sacrificing strength, ideal for applications requiring frequent access. The knurled texture and Phillips No. 2 drive provide dual driving options, reducing slippage and improving operator efficiency. With its coarse metric threading (0.8mm pitch), it offers quick installation and secure retention in panels up to 2.5mm thick, minimizing the risk of stripping and enhancing captive panel screw reliability in vibration-prone settings.
