S-96660A224 M5 x 25 mm ISO 7380-2 Steel Flanged Button Head Hex-Drive Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength of 100,000 psi ensures reliable performance in demanding industrial applications, preventing fastener failure under high stress.
• Superior corrosion resistance from the zinc plating protects the alloy steel core, extending the screw's service life in harsh environments.
• High-strength Class 10.9 rating guarantees consistent performance for critical, heavy-duty fastening tasks requiring maximum reliability.
• Convenient hex drive design with a 3 mm drive size allows for easy and secure installation using standard tools, reducing assembly time.
• Integrated flange on the rounded button head distributes clamping force over a wider area, minimizing surface damage and providing a more secure hold.
• Coarse M5 x 0.8 mm threading enables faster installation and superior performance in softer materials or where vibration resistance is key.
• Precision Class 6h thread fit ensures smooth engagement and a secure connection, reducing the risk of cross-threading and assembly errors.

Professional Applications & Engineering Value

This M5 rounded head hex screw is engineered to solve critical fastening challenges in industrial applications where vibration, high loads, and environmental factors are a concern. The zinc-plated alloy steel construction provides a robust barrier against corrosion, making it ideal for machinery, automotive assemblies, and outdoor equipment. The flanged, button head design not only offers a low-profile, finished appearance but also eliminates the need for a separate washer, simplifying inventory and assembly. The coarse metric thread and partial threading provide excellent grip and resistance to loosening, ensuring long-term joint integrity in heavy-duty fastening scenarios. This combination of material strength, intelligent design, and ISO 7380-2 compliance delivers reliable performance that engineers and procurement specialists can trust.
