Key Features & Benefits at a Glance
- Exceptional tensile strength of 150,000 psi ensures reliable performance in high-stress applications, reducing the risk of fastener failure.
- Superior corrosion resistance from hot-dipped galvanized steel coating extends service life in harsh industrial or outdoor environments.
- High-strength Class 10.9 rating provides consistent load-bearing capacity and durability for heavy-duty structural connections.
- Precise Class 6g thread fit allows for smooth assembly and secure fastening, minimizing installation time and rework.
- Partially threaded design offers optimal grip length (101 mm) for controlled clamping force and vibration resistance.
- Compliance with DIN 6914/ISO 7412 standards guarantees dimensional accuracy and interoperability in metric-based projects.
- External hex drive and hex head facilitate easy installation with standard tools, improving workflow efficiency on-site.
Professional Applications & Engineering Value
Engineered for demanding scenarios, this M24 hex head screw combines hot-dipped galvanized steel construction with a Class 10.9 strength grade to address critical challenges in heavy machinery, construction, and infrastructure. The metric coarse thread with a 3mm pitch ensures rapid assembly and robust load distribution, while the partially threaded shaft enhances grip stability in dynamic or vibrating setups. By meeting DIN 6914 and ISO 7412 specifications, it delivers consistent performance in structural steelwork, bridge building, and industrial equipment, where corrosion resistance and high tensile integrity are paramount for long-term safety and reduced maintenance costs.
Specification Summary & Compliance
This fastener adheres to precise dimensional tolerances, including a Class 6g thread fit per metric standards and a 140 mm length with 39 mm thread length. It conforms to DIN 6914 (equivalent to ISO 7412) for manufacturing consistency and is verified to comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material reliability in global supply chains.
