S-94128A103 M3 DIN 927 Shoulder Screws

Key Features & Benefits at a Glance

• Enhanced Durability - Alloy steel construction with Rockwell B75 hardness provides superior resistance to wear and deformation in demanding industrial environments.
• Precise Alignment - 4mm shoulder diameter with tight tolerances (-0.03mm to 0mm) ensures accurate component positioning and reduces assembly errors.
• Reliable Thread Performance - Class 6g thread fit with M3 x 0.5mm coarse pitch offers excellent engagement and vibration resistance in high-stress applications.
• Space-Saving Design - Headless slotted configuration allows for flush mounting in compact assemblies while maintaining easy installation and removal.
• Consistent Shoulder Length - 5mm shoulder with controlled tolerance (-0.48mm to 0mm) guarantees uniform spacing and reliable pivot point functionality.
• Industry Compliance - Meets DIN 927 specifications and environmental regulations (RoHS 3, REACH) for global manufacturing compatibility.
• Right-Hand Thread Efficiency - Standard thread direction enables quick installation and compatibility with common industrial equipment.

Professional Applications & Engineering Value

This M3 shoulder screw delivers critical precision in machinery where component alignment and rotational stability are paramount. The alloy steel construction with Rockwell B75 hardness withstands repetitive loads and mechanical stress in automated systems, while the precise shoulder fit eliminates play in bearings, linkages, and pivoting mechanisms. The Class 6g thread fit and coarse pitch design ensure secure fastening in vibration-prone equipment, reducing maintenance downtime. Headless slotted drive configuration provides clean aesthetics and accessibility in confined spaces, making it ideal for precision instruments, conveyor systems, and robotic assemblies where reliability and dimensional accuracy are non-negotiable.
