Key Features & Benefits at a Glance
- Exceptional tensile strength of 140,000 psi ensures reliable performance in demanding applications, reducing the risk of fastener failure.
- Superior corrosion resistance from zinc-plated alloy steel construction extends service life in harsh industrial environments.
- High hardness rating (Rockwell C32) provides excellent wear resistance, maintaining thread integrity over repeated use.
- Precision hex drive design allows for secure tool engagement and efficient installation with standard 2mm hex keys.
- Fully threaded coarse pitch enables faster assembly and strong holding power in various materials.
- Rounded button head profile offers a low-profile, aesthetically pleasing finish while minimizing snagging risks.
- International standard compliance (ISO 7380) guarantees dimensional accuracy and interchangeability across global applications.
Professional Applications & Engineering Value
These Class 10.9 metric hex screws deliver critical engineering solutions where high tensile strength and corrosion resistance are paramount. The zinc-plated alloy steel construction combined with fully threaded M3 coarse pitch design provides superior vibration resistance and load distribution in heavy machinery, automotive assemblies, and industrial equipment. The rounded button head with hex drive ensures flush mounting in confined spaces while preventing tool slippage during high-torque applications. Engineered to withstand extreme mechanical stresses, these ISO 7380 compliant fasteners eliminate compatibility issues in global supply chains, making them ideal for OEM manufacturing and maintenance operations requiring precision metric screws with verified performance credentials.
Specification Summary & Compliance
Manufactured to ISO 7380 specifications with Class 6g thread fit tolerance for precise engagement. The M3 x 0.5mm coarse thread configuration maintains 30mm length accuracy while the rounded head design conforms to standardized dimensions. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations ensures safe usage across regulated industries. The Class 10.9 strength rating corresponds to 140,000 psi tensile strength with verified Rockwell C32 hardness for consistent mechanical performance.
