S-90269A882 M16 ISO 7379 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance in harsh environments due to 316 Stainless Steel construction and protective Black Oxide finish.
• Exceptional mechanical strength with a tensile strength of 70,000 psi and a minimum shear strength of 35,000 psi for reliable load-bearing applications.
• Precise alignment and spacing ensured by the integral 20mm diameter shoulder with controlled tolerances, reducing component wear.
• Secure, non-slip installation facilitated by the knurled head and 10mm hex socket drive, allowing for high-torque tightening.
• Wide compatibility and easy assembly with a standard M16x2mm coarse right-hand thread conforming to Class 5g6g fit for consistent performance.
• Enhanced durability and hardness with a Rockwell B79 rating, ensuring the screw maintains its integrity under repeated use.
• Guaranteed regulatory compliance meeting ISO 7379, RoHS 3, and REACH standards for safe and sustainable use in regulated industries.

Professional Applications & Engineering Value

This M16 shoulder screw is engineered to address critical challenges in precision assembly and machinery. The 316 Stainless Steel material provides excellent resistance to corrosion, making it ideal for marine, chemical processing, and food-grade equipment where moisture and chemicals are prevalent. The Black Oxide finish not only enhances corrosion protection but also reduces galling during installation. The 20mm shoulder diameter acts as a precise pivot, spacer, or bearing surface, preventing axial movement and misalignment in rotating assemblies like conveyor systems, automotive jigs, and robotic arms. The combination of a hex socket drive and knurled head ensures a firm grip for high-torque applications, reducing the risk of tool slippage and damage. With its coarse metric thread and high tensile strength, this fastener delivers reliable clamping force and vibration resistance in demanding industrial settings, ensuring long-term operational stability and reduced maintenance costs.

Specification Summary & Compliance
