M3 x 4mm Slotted Grub Screw Cup Point A1 Stainless Steel DIN 438
The M3 x 4mm slotted cup point set screw steps up from the 3mm with a third more thread engagement - useful when a single diameter of contact is not enough to hold reliably under light operational loads. Suited to PCB-mount shaft locks, miniature stepper motor collars and small instrument dials where the assembly is compact but the headless set screw needs to resist light torque without slipping. The cup point protects smooth and ground shaft surfaces from bruising. Tighten with a flat-head screwdriver or slotted bit. A1 stainless steel, non-magnetic. DIN 438 / ISO 7436 compliant.
Common Applications
- PCB-mount shaft locks and stepper motor collars
- Small instrument dial and encoder shaft retention
- Light torque resistance in miniature rotating assemblies
- Smooth and ground shaft surface protection applications
