• Consistent and Reliable Thread Engagement: The Class 6g thread fit on the M10x1.5 coarse thread ensures easy assembly and a secure, vibration-resistant connection.
• Enhanced Material Hardness: A Rockwell B55 hardness rating provides excellent resistance to deformation and galling, extending the screw's service life.
• Global Regulatory Compliance: Meets DIN 923 specifications and is RoHS 3 & REACH compliant, ensuring safety and environmental standards for international markets.

Professional Applications & Engineering Value

This M10 shoulder screw is engineered to address critical alignment and durability challenges in precision machinery. The 18-8 stainless steel construction provides excellent resistance to corrosion and oxidation, making it ideal for applications in food processing, medical devices, and outdoor equipment where moisture is a concern. The 16mm shoulder length with its precise tolerance acts as a pivot or axle, ensuring components like gears, pulleys, and linkages rotate freely without lateral movement, which reduces wear and prevents premature failure. The low socket head design is particularly valuable in compact assemblies, allowing for a flush fit that maximizes space efficiency. Combined with the coarse thread (1.5mm pitch) and Class 6g thread fit, installation is swift and reliable, even in high-vibration environments, providing engineers with a dependable component for maintaining operational integrity and reducing downtime.
