Key Features & Benefits at a Glance
- Exceptional tensile strength of 140,000 psi ensures reliable performance in high-stress applications, reducing the risk of fastener failure.
- Superior corrosion resistance from the black-oxide finish on alloy steel extends service life in harsh industrial environments.
- High hardness rating (Rockwell C32) provides excellent wear resistance, maintaining thread integrity through repeated use.
- Coarse thread pitch (1.5mm) allows for quicker installation and better grip in softer materials or where vibration is a concern.
- Fully threaded design offers consistent clamping force along the entire 90mm length for secure fastening in deep applications.
- Precision Class 6g thread fit ensures smooth assembly and compatibility with standard metric nuts and tapped holes.
- Hex drive (6mm) enables easy installation with common tools, reducing assembly time and labor costs.
Professional Applications & Engineering Value
Engineered for demanding industrial settings, this M10 hex screw with Class 10.9 strength and black-oxide alloy steel construction addresses critical challenges in machinery assembly, structural frameworks, and heavy equipment. The fully threaded metric design ensures uniform load distribution, preventing loosening under vibration—common in automotive, construction, and manufacturing applications. Its coarse thread pitch facilitates rapid installation in materials like cast iron or aluminum, while the rounded head profile minimizes protrusion risks. Compliant with ISO 7380, it guarantees dimensional accuracy and interoperability, making it ideal for OEMs and maintenance teams seeking durability and regulatory adherence without compromising on performance.
Specification Summary & Compliance
This fastener adheres to ISO 7380 standards for dimensional precision, with a Class 6g thread fit ensuring consistent engagement. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance for environmental safety, and is manufactured to Class 10.9 strength grade, verifying high tensile and yield capabilities suitable for critical industrial use.
