S-90265A273 M6 ISO 7379 Shoulder Screws

Key Features & Benefits at a Glance

• Corrosion-resistant 18-8 stainless steel construction ensures long-term reliability in harsh industrial environments, reducing maintenance costs and downtime.
• Precision 65mm shoulder with tight length tolerance (0 to 0.25mm) provides accurate alignment and spacing for rotating components like gears and pulleys.
• High tensile strength (70,000 psi) and Rockwell B83 hardness deliver exceptional load-bearing capacity and resistance to deformation under stress.
• Knurled head with 4mm hex drive offers superior grip and torque transmission, preventing tool slippage during installation.
• Class 5g6g thread fit and M6x1mm coarse pitch enable quick assembly and secure fastening with standard metric tools.
• Compliance with ISO 7379, RoHS 3, and REACH standards guarantees consistent quality, safety, and environmental responsibility for global supply chains.
• Right-hand thread and 11mm thread length facilitate easy integration and reliable retention in diverse mechanical applications.

Professional Applications & Engineering Value

This M6 shoulder screw is engineered to address critical alignment and wear issues in precision assemblies. The 65mm shoulder length acts as a built-in pivot or spacer, eliminating the need for additional bushings in machinery like conveyor systems, automotive transmissions, and robotic arms. Made from 18-8 stainless steel, it resists oxidation and chemical exposure, ideal for food processing, marine, or outdoor equipment. The knurled head enhances handling in oily or gloved conditions, while the 4mm hex drive ensures efficient torque application. By meeting ISO 7379 specifications, it provides interchangeability and reduces assembly errors, streamlining production workflows for OEMs and maintenance teams.

Specification Summary & Compliance

The screw features a Class 5g6g thread fit per metric standards, with a shoulder diameter tolerance of -0.072 to -0.01 mm for precise fits. It conforms to ISO 7379 for dimensional consistency and is manufactured to comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring no restricted substances are used. This guarantees reliability and environmental safety in industrial applications.
