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 for securing gears, pulleys, and collars on shafts. The 120° cone point creates permanent seating impressions in mating materials, preventing rotational slip in high-torque applications. With its headless design and 2mm hex drive, it eliminates protrusions in machinery while allowing secure tool engagement. The Class 5g6g thread fit ensures precise engagement in coarse thread applications across automotive, manufacturing, and precision equipment assemblies. Certified to DIN 914 and ISO 4027 standards, this metric set screw guarantees dimensional consistency for global manufacturing operations.
