- Precise thread engagement with Class 5g6g fine thread fit (1.5mm pitch) ensuring vibration resistance and reliable performance
- Easy installation and removal using standard 6mm hex keys in confined spaces due to headless design
- Global compatibility meeting both DIN 916 and ISO 4029 standards for consistent quality in international applications
- Environmental compliance with RoHS 3 and REACH regulations, making them suitable for regulated industries worldwide
- Optimized for metric systems with M12 x 20mm right-hand thread dimensions for seamless integration into existing designs
Professional Applications & Engineering Value
This M12 alloy steel set screw delivers critical engineering solutions where permanent positioning and torque transmission are paramount. The cup point tip creates concentrated pressure that digs into shaft surfaces, preventing rotational slippage in pulleys, gears, and collars—solving common loosening issues in high-vibration environments. Manufactured from Rockwell C45 hardened alloy steel, it maintains dimensional stability under repeated stress cycles, while the fine thread pitch (1.5mm) provides superior resistance to vibrational loosening compared to coarse threads. The headless hex drive design allows flush mounting in space-constrained assemblies, making it ideal for precision machinery, automotive components, and industrial equipment where reliability cannot be compromised.
Specification Summary & Compliance
This metric set screw features M12 x 1.5mm fine threads with Class 5g6g thread fit tolerance per ISO standards, ensuring precise dimensional accuracy. Manufacturing complies with DIN 916 and ISO 4029 specifications for consistent quality and performance. The product is fully RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, meeting current environmental regulations for hazardous substance restrictions.
