Professional Applications & Engineering Value

This alloy steel set screw delivers exceptional engineering value in applications requiring precise component positioning and secure fastening. The M3 metric thread with 0.5 mm coarse pitch provides excellent holding strength while allowing for efficient installation in time-sensitive production environments. The headless design combined with the 90° cone point creates a flush-mounted solution that applies concentrated pressure for permanent positioning of gears, pulleys, and collars on shafts. Engineered to DIN 914 and ISO 4027 standards, this hex drive set screw ensures compatibility with existing tooling and manufacturing processes. The Rockwell C45 hardness rating guarantees the screw maintains its structural integrity under vibration and rotational stresses common in machinery, automotive, and precision equipment applications.
