Key Features & Benefits at a Glance
- Exceptional durability with Class 10.9 strength grade and 140,000 psi tensile strength for reliable performance in high-stress industrial environments
- Superior corrosion resistance thanks to the black-oxide coating on alloy steel, extending service life in demanding conditions
- Secure fastening with precise fit through Class 6g thread tolerance and M10x1.5 coarse pitch design for quick installation and vibration resistance
- Easy installation and removal with 6 mm hex drive and rounded button head profile, reducing assembly time and tool slippage
- Full thread engagement along the 18 mm length ensures maximum holding power across the entire fastener
- Consistent quality assurance with ISO 7380 compliance, guaranteeing dimensional accuracy and interchangeability
- Environmentally responsible manufacturing through RoHS 3 and REACH compliance, meeting global regulatory standards
Professional Applications & Engineering Value
This M10 hex button head screw delivers critical engineering advantages in machinery assembly, automotive components, and heavy equipment where vibration resistance and structural integrity are paramount. The black-oxide alloy steel construction combined with Class 10.9 strength rating (Rockwell C32 hardness) prevents stripping and fatigue failure under dynamic loads. The fully threaded coarse pitch design enables rapid installation while maintaining clamp load in thick materials. With its low-profile rounded head and hex drive, it solves space-constrained applications where socket heads protrude excessively, making it ideal for CNC machinery, industrial frames, and precision equipment requiring flush mounting and repeated maintenance access.
Specification Summary & Compliance
Manufactured to ISO 7380 specifications with Class 6g thread fit tolerance for precise engagement. The metric M10x1.5 coarse thread and 18 mm length maintain dimensional consistency across applications. Complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in regulated industries. The black-oxide surface treatment provides consistent corrosion protection while meeting international fastener standards for reliability and performance.
