Professional Applications & Engineering Value

This **M8 set screw** is engineered to solve critical alignment and slippage issues in **precision assemblies**. The **120° cone point** creates a concentrated contact area that digs into shafts, pulleys, and gears, preventing rotational movement under high torque loads. Manufactured from **18-8 stainless steel**, it resists oxidation and chemical degradation in manufacturing, automotive, and machinery applications. The **coarse thread** with **1.25mm pitch** enables rapid installation while maintaining **Class 6g tolerance** for vibration-resistant connections. Its **headless design** and **hex socket drive** make it ideal for confined spaces where flush mounting is required, ensuring reliable performance in demanding **industrial fastening** scenarios.

Specification Summary & Compliance

This metric **set screw** features M8x1.25 coarse threads with **Class 6g thread fit** per ISO standards, ensuring precise dimensional accuracy. It complies with **DIN 914** and **ISO 4027** manufacturing specifications for consistent quality. The product meets **RoHS 3 (2015/863/EU)** and **REACH (EC 1907/2006)** environmental regulations, confirming it is free of restricted hazardous substances and safe for industrial use worldwide.
