S-90269A907 M16 ISO 7379 Shoulder Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with 316 Stainless Steel construction, ideal for harsh environments like chemical processing or marine applications.
• Superior mechanical strength offering 70,000 psi tensile and 35,000 psi shear strength for reliable performance under high-stress loads.
• Enhanced grip and anti-tampering from the knurled head design, preventing slippage during installation with standard hex drive.
• Precise component alignment enabled by the 45mm shoulder with tight length tolerance (±0.25mm), reducing assembly errors.
• Durable, wear-resistant surface thanks to the Black Oxide finish, which also provides a sleek, low-reflectivity appearance.
• Wide industrial compatibility with M16x2mm coarse thread and Class 5g6g fit, ensuring easy integration into metric systems.
• Regulatory peace of mind by meeting ISO 7379 standards and being RoHS 3/REACH compliant for global supply chain requirements.

Professional Applications & Engineering Value

This M16 shoulder screw is engineered to address critical alignment and durability challenges in industrial applications. The 316 Stainless Steel material provides excellent resistance to corrosive agents, making it suitable for machinery in aggressive environments like food processing, marine equipment, and chemical plants. The 45mm shoulder length with minimal tolerance ensures precise positioning of moving parts, such as in gears, pulleys, and linkages, reducing wear and maintenance downtime. Combined with the Black Oxide finish, it offers added protection against rust and galling, while the knurled head and 10mm hex drive facilitate secure, tool-friendly installation. This socket head shoulder screw delivers reliable performance in high-vibration settings, ensuring long-term operational stability and cost efficiency.

Specification Summary & Compliance

This shoulder screw adheres to ISO 7379 specifications, with a Class 5g6g thread fit for consistent engagement in metric assemblies. The shoulder diameter tolerance is tightly controlled at -0.072 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm, ensuring high dimensional accuracy. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, supporting safe and sustainable use in global markets.
