S-94128A115 M5 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 - 6.5mm shoulder diameter with tight tolerance (-0.036mm to 0mm) ensures accurate component positioning and reduces assembly misalignment.
• Reliable Fastening - Class 6g thread fit with 0.8mm coarse pitch offers consistent engagement and vibration resistance in high-stress applications.
• Space-Efficient Design - Headless, slotted drive configuration allows for compact installations and easy adjustment in confined machinery spaces.
• Regulatory Compliance - Meets DIN 927 specifications while being RoHS 3 and REACH compliant for safe use in regulated industries.
• Optimized Load Distribution - 12mm shoulder length with ±0.7mm tolerance provides stable bearing surface for rotating components and pivoting mechanisms.
• Quick Installation - Right-hand coarse threading enables faster assembly compared to fine-pitch alternatives, reducing production time.

Professional Applications & Engineering Value

This precision shoulder screw addresses critical alignment challenges in mechanical assemblies where component positioning directly impacts operational accuracy. The alloy steel construction maintains dimensional stability under mechanical stress, while the Class 6g thread fit prevents loosening in vibrating equipment. The 12mm shoulder with tight tolerances serves as an exact locating diameter for gears, bearings, and linkages, eliminating the need for additional spacing components. Particularly valuable in automation systems, printing machinery, and precision instruments, this DIN 927 compliant fastener ensures repeatable performance in applications requiring exact axial and radial positioning. The slotted drive design facilitates both installation and maintenance operations in hard-to-reach assembly areas.

Specification Summary & Compliance
