S-97713A128 M16 DIN 609 Shoulder Screws

Key Features & Benefits at a Glance

• Precision alignment and reduced assembly time with a standard shoulder fit and tight diameter tolerance (0.001 to 0.012 mm) for consistent positioning in mating parts.
• Exceptional load-bearing capacity and durability thanks to 120,000 psi tensile strength and Rockwell C20 hardness, ensuring reliable performance under stress.
• Secure and efficient torque application with an external 24mm hex head and smooth texture, allowing for high tightening forces without slippage.
• Robust thread engagement and vibration resistance from the M16x2mm coarse pitch, Class 6g thread, ideal for high-vibration industrial environments.
• Versatile integration in metric assemblies with a 29.5mm shoulder length and right-hand thread, conforming to DIN 609 for broad compatibility.
• Enhanced safety and environmental compliance by meeting RoHS 3 and REACH regulations, reducing risks in sensitive applications.
• Cost-effective maintenance and long service life due to high-strength steel construction, minimizing replacements in demanding conditions.

Professional Applications & Engineering Value

This M16 shoulder screw is engineered to address common industrial challenges such as misalignment and component wear in precision machinery. The steel material with Rockwell C20 hardness provides excellent resistance to deformation, while the external hex head ensures easy installation with standard tools, reducing assembly time. The Class 6g thread fit and coarse pitch offer reliable fastening in high-vibration settings like automotive or manufacturing equipment, preventing loosening. With a shoulder length of 29.5mm and tight tolerances, it facilitates accurate pivoting or spacing in linkages, bearings, and robotic arms, enhancing overall system reliability and reducing downtime.
