Professional Applications & Engineering Value

This M8 alloy steel set screw is engineered to solve critical challenges in industrial assembly and precision machinery. Its headless design and extended tip provide a flush finish while maximizing grip in blind holes or on shafts, preventing component slippage under dynamic loads. The Rockwell C45 hardness ensures the screw withstands shear forces and repeated adjustments without deforming, making it ideal for permanent positioning in gears, collars, and pulleys. Manufactured to DIN 915 / ISO 4028 standards with a Class 6g thread fit, it delivers consistent performance in metric coarse thread applications, reducing the risk of cross-threading and assembly errors. The right-hand thread and hex drive facilitate quick installation with standard tools, enhancing productivity in automated or manual settings.

Specification Summary & Compliance

This set screw features an M8x1.25mm metric coarse thread with Class 6g tolerance for precise fit. The extended tip has a diameter of 5.5mm (-0.3mm tolerance) and length of 4.3mm (-0.3mm to 0 tolerance). It is manufactured from alloy steel hardened to Rockwell C45 and complies with DIN 915 and ISO 4028 specifications. The product is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting international environmental and safety standards for industrial use.
