Professional Applications & Engineering Value

These M3 brass set screws solve critical alignment and corrosion challenges in precision assemblies. The Class 6g thread fit maintains tight tolerances for secure fastening in vibrating equipment, while the corrosion-resistant brass material prevents degradation in electrical components and marine applications. The slotted headless design enables flush installation in tight spaces where protruding fasteners would interfere with moving parts. Commonly specified for shaft collars, gear positioning, and precision instrument manufacturing, these metric set screws provide reliable clamping force without damaging shaft surfaces thanks to the flat tip configuration. Their coarse thread pitch ensures rapid installation in high-volume production environments while maintaining vibration resistance.

Specification Summary & Compliance
