Professional Applications & Engineering Value
This M12 set screw delivers critical engineering solutions where vibration resistance and precise positioning are paramount. The extra fine thread with 1.25mm pitch provides superior adjustment control compared to standard pitches, making it ideal for precision machinery, optical equipment, and automotive assemblies where minute adjustments matter. The cup point design creates permanent indentations in shaft components, preventing rotational movement under dynamic loads. Manufactured from alloy steel with Rockwell C45 hardness, this headless set screw maintains its mechanical properties in high-stress environments while the hex drive ensures reliable installation in confined spaces common in industrial equipment and manufacturing fixtures.
Specification Summary & Compliance
This metric set screw features M12 x 1.25mm extra fine thread with Class 5g6g thread fit per ISO standards, ensuring precise dimensional accuracy and interchangeability. The 30mm length with cup point tip provides consistent performance across applications. Manufacturing complies with DIN 916/ISO 4029 specifications for dimensional and mechanical requirements. Environmental compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted substances for industrial use worldwide.
