Professional Applications & Engineering Value

This M4 set screw delivers critical engineering solutions where space constraints and vibration resistance are paramount. The alloy steel composition with Rockwell B67 hardness provides superior resistance to shear forces in machinery, automotive, and precision equipment applications. The headless design with slotted drive allows for seamless integration into rotating components and tight assemblies where traditional bolt heads would interfere. The metric coarse threading (M4 x 0.7mm) ensures rapid installation while maintaining holding power in both soft and hard materials. The flat tip configuration creates optimal clamping force distribution, preventing damage to shaft surfaces while securely locking components against rotational or axial movement. This combination of features makes it ideal for permanent fastening in high-vibration environments where reliability cannot be compromised.

Specification Summary & Compliance
