S-92981A606 M16 ISO 7379 Shoulder Screws

Key Features & Benefits at a Glance

• Exceptional load-bearing capacity with 140,000 psi tensile strength and 84,000 psi minimum shear strength for reliable performance in high-stress assemblies.
• Precise component alignment and smooth rotation due to the 20mm shoulder diameter with tight tolerance, reducing wear and simplifying installation.
• Superior corrosion resistance and reduced light reflection from the black oxide finish, extending service life in harsh industrial environments.
• High torque application capability with the 10mm hex socket drive, ensuring secure fastening and reducing the risk of stripping.
• Optimized for rapid assembly with a coarse M16x2mm right-hand thread, allowing for quicker installation compared to fine-pitch alternatives.
• Consistent dimensional accuracy meeting ISO 7379 standards and Class 4g6g thread fit, ensuring interchangeability and reliable performance.
• Enhanced durability and wear resistance from alloy steel heat-treated to Rockwell C32 hardness, suitable for repetitive use and heavy-duty applications.

Professional Applications & Engineering Value

This M16 shoulder screw is engineered to address common challenges in precision machinery and industrial equipment, such as misalignment and component wear. The alloy steel construction, combined with a black oxide finish, provides excellent resistance to corrosion and abrasion, making it ideal for use in automotive assemblies, conveyor systems, and robotic arms. The smooth shoulder with a diameter of 20mm acts as a pivot or bearing surface, ensuring accurate alignment of moving parts and reducing friction. With a coarse metric thread and 10mm hex drive, it allows for quick, secure fastening in high-vibration environments, minimizing downtime and maintenance costs. This socket head shoulder screw delivers reliable performance in demanding applications where precision and strength are critical.

Specification Summary & Compliance
