Key Features & Benefits at a Glance
- Exceptional strength and reliability with Class 10.9 rating and 140,000 psi tensile strength, ensuring secure fastening in demanding industrial environments.
- Superior corrosion resistance thanks to the black-oxide coating on alloy steel, extending service life in harsh conditions.
- Optimized for high-torque applications featuring a hex socket drive (3 mm) and rounded button head for easy installation and reduced risk of stripping.
- Precise and durable threading with M5 coarse thread (0.8 mm pitch) and Class 6g fit, providing consistent engagement and vibration resistance.
- Full threading along the 18 mm length allows for maximum grip and adjustability in various material thicknesses.
- High hardness (Rockwell C32) ensures excellent wear resistance and maintains fastener integrity under repeated stress.
- Compliance with international standards including ISO 7380, RoHS 3, and REACH, guaranteeing safety and environmental responsibility.
Professional Applications & Engineering Value
This M5 hex socket screw is engineered to address critical challenges in industrial fastening, where vibration, heavy loads, and corrosive environments can compromise joint integrity. The black-oxide alloy steel construction provides a robust barrier against rust and wear, while the Class 10.9 strength grade ensures it withstands high tensile and dynamic stresses without failure. The fully threaded design and coarse thread pitch enable quick assembly and reliable holding power in metals, plastics, and composites. Ideal for machinery, automotive, and equipment manufacturing, this ISO 7380 compliant screw delivers consistent performance, reducing maintenance needs and downtime in high-strength applications.
Specification Summary & Compliance
This fastener adheres to precise dimensional tolerances, including Class 6g thread fit for metric coarse threads (M5 x 0.8 mm) and an 18 mm length. It conforms to ISO 7380 for rounded head hex socket screws and meets regulatory requirements such as RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), ensuring it is free from hazardous substances and suitable for global industrial use.
