Key Features & Benefits at a Glance
- Exceptional tensile strength of 170,000 psi ensures reliable performance in high-stress applications, reducing the risk of fastener failure.
- Superior corrosion resistance from the black-oxide coating extends service life in harsh industrial environments, minimizing maintenance needs.
- Precise Class 5g6g thread fit provides consistent engagement and reduces the likelihood of cross-threading during assembly.
- High hardness (Rockwell C37) offers excellent wear resistance, maintaining thread integrity over repeated use.
- Standard hex drive (19mm) allows for easy installation and removal with common tools, improving workflow efficiency.
- Full threading ensures uniform load distribution along the entire length, enhancing joint stability.
- Compliance with DIN 912/ISO 4762 guarantees dimensional accuracy and interchangeability, supporting global engineering standards.
Professional Applications & Engineering Value
This M27x3mm Class 12.9 black-oxide alloy steel socket head cap screw is engineered to address critical challenges in heavy-duty industrial settings. Its high tensile strength and Rockwell C37 hardness make it ideal for applications subject to dynamic loads and vibration, such as machinery assembly, automotive systems, and construction equipment. The coarse thread pitch and right-hand thread direction facilitate quick installation in tough materials, while the black-oxide surface treatment provides a durable barrier against moisture and chemicals, reducing corrosion-related downtime. By meeting DIN 912/ISO 4762 specifications, it ensures reliable performance in precision engineering projects, offering a robust solution for demanding industrial fastening needs.
Specification Summary & Compliance
This product features a metric thread size M27x3mm with a Class 5g6g thread fit for precise tolerance.
