Professional Applications & Engineering Value
These M4 set screws are engineered to solve critical fastening challenges in industrial machinery, automotive assemblies, and precision equipment. The alloy steel material, combined with Rockwell B67 hardness, provides excellent resistance to wear and deformation, ensuring reliable performance in high-vibration environments. The headless, slotted design allows for seamless integration where protruding fastener heads are not feasible, while the coarse metric thread with 0.7 mm pitch facilitates rapid installation and strong grip in softer materials or pre-tapped holes. This makes them ideal for securing gears, pulleys, and collars onto shafts, offering a dependable set screw solution that minimizes maintenance and downtime.
Specification Summary & Compliance
This M4 x 0.7 mm x 25 mm set screw features a Class 6g thread fit per ISO metric standards, ensuring precise dimensional tolerances for consistent performance. Manufactured in compliance with DIN 551 and ISO 4766 specifications, it guarantees adherence to international engineering norms. The product is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, confirming its safety and environmental responsibility for global supply chains.
