S-91273A494 M16 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance thanks to 18-8 Stainless Steel construction, ideal for harsh environments and long-term reliability.
• Precise component alignment and pivot points enabled by the 60mm shoulder with a tightly controlled diameter tolerance.
• High mechanical strength with a tensile strength of 70,000 psi and a shear strength of 35,000 psi for demanding applications.
• Secure and non-slip installation provided by the knurled socket head, ensuring a firm grip with standard hex tools.
• Reliable and consistent thread engagement guaranteed by the Class 5g6g metric coarse thread (M16x2).
• Compliance with major environmental regulations including RoHS 3 and REACH, ensuring safety and global market acceptance.
• Optimized for automated assembly with a standard socket head profile and right-hand thread for efficient production lines.

Professional Applications & Engineering Value

This M16 shoulder screw is engineered to solve critical alignment and rotational challenges in industrial assemblies. The 60mm shoulder length acts as a precise shaft or pivot, eliminating the need for additional bushings or spacers, which reduces parts count and assembly time. Manufactured from 18-8 Stainless Steel, it offers excellent resistance to rust and corrosion, making it suitable for machinery, food processing equipment, and outdoor applications. The Class 5g6g thread fit and coarse pitch (M16x2) ensure rapid assembly and high vibration resistance, while the knurled socket head prevents tool slippage during high-torque installation. This combination of precision, high tensile strength, and durability provides long-term value by minimizing maintenance and component failure in demanding industrial shoulder screw applications.

Specification Summary & Compliance

This precision shoulder screw features an M16x2 metric coarse thread with a Class 5g6g thread fit for reliable performance. The shoulder diameter is held to a tight tolerance of -0.04 to -0.01 mm, and the shoulder length tolerance is 0 to +0.25 mm, ensuring precise fitment. The component is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its adherence to strict environmental and safety standards for industrial use.
