S-91306A773 M8 x 10 mm ISO 7380 Steel Button Head Hex-Drive Screws

Key Features & Benefits at a Glance

• Exceptional load-bearing capacity with Class 10.9 strength grade and 140,000 psi tensile strength for reliable performance in demanding applications
• Superior corrosion resistance through zinc-plated alloy steel construction, extending service life in harsh industrial environments
• Optimized installation efficiency with 5mm hex drive design providing secure tool engagement and reduced slipping
• Enhanced thread engagement through M8 coarse pitch (1.25mm) design, allowing faster assembly and reduced cross-threading risks
• Consistent dimensional accuracy with Class 6g thread fit ensuring reliable mating with standard nuts and threaded components
• Reduced surface protrusion with low-profile button head design (4.4mm height) for applications with limited clearance requirements
• Full regulatory compliance meeting ISO 7380 specifications and environmental standards including RoHS 3 and REACH

Professional Applications & Engineering Value

Engineered for industrial machinery assembly and heavy-duty equipment manufacturing, these M8 metric screws deliver critical performance where vibration resistance and structural integrity are paramount. The zinc-plated alloy steel construction provides essential protection against environmental degradation, while the fully threaded design ensures maximum grip length across the entire fastener. The rounded button head profile offers both aesthetic appeal and functional safety by eliminating sharp edges, making these hex drive screws ideal for applications requiring frequent maintenance access. With Rockwell C32 hardness and Class 10.9 strength rating, they withstand significant dynamic loads without compromising thread integrity, solving common failure points in vibrating machinery and structural frameworks.
