S-90278A242 M6 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments and extended service life.
• Precise component alignment enabled by the precisely machined shoulder with tight diameter tolerance (-0.025 to 0 mm) and length tolerance (0 to 0.05 mm).
• High mechanical strength and durability from a Rockwell B55 hardness and 70,000 psi tensile strength, ensuring reliable performance under load.
• Secure and efficient installation with a standard hex socket head (4 mm drive), providing a positive grip and reducing the risk of tool slippage.
• Wide compatibility and easy assembly thanks to the standard M6x1 mm coarse metric thread with a Class 6g fit for common industrial applications.
• Compliance with major environmental regulations including RoHS 3 and REACH, ensuring suitability for global markets and responsible manufacturing.
• Versatile right-hand thread design for straightforward installation in a broad range of machinery and assembly operations.

Professional Applications & Engineering Value

This M6 shoulder screw is engineered to address critical alignment and pivot point requirements in industrial applications. The 35mm shoulder length acts as a precise datum for locating parts like gears, bearings, and linkages, eliminating the need for additional spacers or bushings and reducing assembly time and complexity. Manufactured from 18-8 Stainless Steel, it offers excellent resistance to rust and corrosion, which is vital for equipment in demanding environments such as food processing, packaging machinery, and outdoor apparatus. The socket head with a 4 mm hex drive allows for high torque application in confined spaces, ensuring a secure fastening. The Class 6g thread fit and coarse 1mm pitch provide robust engagement and vibration resistance, making these precision shoulder screws a reliable choice for high-cycle mechanical systems.
