S-91306A794 M10 x 70 mm ISO 7380 Steel Button Head Hex-Drive Screws

Key Features & Benefits at a Glance

• Exceptional load-bearing capability with Class 10.9 strength grade and 140,000 psi tensile strength for reliable performance in demanding applications.
• Superior corrosion resistance provided by zinc-plated alloy steel construction, extending service life in harsh industrial environments.
• Optimized torque transmission through the 6mm hex drive design, preventing stripping and ensuring secure installation.
• Enhanced fatigue resistance from Rockwell C32 hardness, maintaining structural integrity under repeated stress cycles.
• Simplified assembly process with coarse M10x1.5mm threading and Class 6g fit, enabling quick installation while maintaining vibration resistance.
• Reduced surface damage risk due to the rounded button head profile, making it ideal for applications requiring flush mounting.
• Guaranteed dimensional consistency through full compliance with ISO 7380 manufacturing specifications.

Professional Applications & Engineering Value

This Class 10.9 metric hex screw delivers critical engineering advantages for industrial machinery, automotive assemblies, and structural frameworks where high tensile strength and vibration resistance are paramount. The zinc-plated alloy steel construction provides essential corrosion protection in environments exposed to moisture or chemicals, while the fully threaded M10x1.5mm coarse thread design ensures maximum grip length and faster installation compared to fine-thread alternatives. The rounded button head with 6mm hex drive offers both aesthetic appeal and practical benefits, eliminating sharp edges that could damage surrounding components while providing sufficient torque capability for secure fastening. These characteristics make it particularly valuable for applications requiring repeated disassembly and reassembly, as the combination of Rockwell C32 hardness and precise Class 6g thread fit maintains thread integrity through multiple installation cycles.

Specification Summary & Compliance

Manufactured to ISO 7380 standards with Class 6g thread tolerance for consistent dimensional accuracy. The fastener features M10x1.5mm coarse threads with right-hand direction and full threading along the 70mm length. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental responsibility and workplace safety. The Class 10.9 strength rating corresponds to 140,000 psi minimum tensile strength with Rockwell C32 hardness verification.
