Key Features & Benefits at a Glance
- Exceptional durability with Class 10.9 strength grade and 140,000 psi tensile strength, ensuring reliable performance in high-stress industrial environments.
- Superior corrosion resistance provided by zinc-plated alloy steel, extending service life in humid or corrosive conditions.
- Easy installation and removal with a 2 mm hex drive and button head design, allowing for efficient assembly with standard tools.
- Precise thread engagement due to Class 6g thread fit and coarse 0.5 mm pitch, reducing cross-threading risks and improving joint integrity.
- Full threading for maximum grip along the 6 mm length, distributing load evenly and enhancing fastener stability.
- High hardness of Rockwell C32 minimizes wear and deformation, maintaining fastener integrity over repeated use.
- Compliance with international standards including ISO 7380, RoHS 3, and REACH, ensuring safety and environmental responsibility.
Professional Applications & Engineering Value
This M3 hex button head screw is engineered for demanding applications where reliability and strength are critical. Made from zinc-plated alloy steel, it offers excellent corrosion resistance, making it ideal for machinery, automotive assemblies, and electronic enclosures exposed to harsh conditions. The fully threaded design and coarse metric thread with 0.5 mm pitch ensure quick, secure fastening, reducing installation time and preventing loosening under vibration. With a Class 10.9 strength grade and Rockwell C32 hardness, it withstands high tensile loads and repetitive stress, solving common issues like fastener failure in heavy-duty equipment. The rounded head and hex drive provide a low-profile, tool-friendly solution that meets ISO 7380 specifications, delivering consistent performance in industrial fastening systems.
Specification Summary & Compliance
This screw features precise metric thread dimensions (M3 x 0.5 mm pitch) with a Class 6g thread fit for accurate tolerance, ensuring compatibility with standard nuts and threaded holes. It adheres to ISO 7380 for dimensional consistency and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free from hazardous substances and safe for various industrial uses.
