Professional Applications & Engineering Value
This M4 set screw delivers critical engineering solutions where space constraints and vibration resistance are paramount. The alloy steel construction with Rockwell C45 hardness provides exceptional shear strength, preventing failure under dynamic loads in machinery, automotive assemblies, and precision equipment. The hex drive design ensures maximum torque application without cam-out, while the headless configuration and flat tip create secure, flush fastenings in pulleys, gears, and collars. Meeting DIN 913/ISO 4026 standards, these metric set screws with coarse threading offer reliable performance in high-vibration environments, making them ideal for manufacturing, robotics, and industrial maintenance applications where precision and durability are non-negotiable.
Specification Summary & Compliance
This set screw maintains Class 5g6g thread tolerance according to metric standards, ensuring precise fitment in threaded components. Manufacturing complies with DIN 913 ISO 4026 specifications for dimensional accuracy and performance. The product is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting current environmental and safety regulations for industrial use.
