Professional Applications & Engineering Value

This M5 set screw is engineered to solve critical challenges in industrial applications where space is limited and a secure, permanent fastening is required. The headless design and flat tip allow it to sit completely flush, making it ideal for securing pulleys, gears, and collars onto shafts without protruding components. Manufactured from high-grade alloy steel and heat-treated to a Rockwell C45 hardness, it provides exceptional resistance to vibrational loosening and shear forces. The coarse metric thread (M5x0.8mm) ensures rapid installation and a strong grip in a variety of materials, while the internal hex drive offers superior torque capability compared to slotted alternatives. Complying with DIN 913 and ISO 4026 standards, this set screw delivers reliable, repeatable performance for machinery, automotive, and precision equipment assembly.
