Professional Applications & Engineering Value

This M16 shoulder screw is engineered to address critical challenges in industrial assembly, such as misalignment and component wear. The 316 Stainless Steel material provides excellent resistance to corrosion from chemicals, moisture, and salt, making it suitable for marine, chemical processing, and food machinery applications. The precision shoulder with a diameter of 20mm and length of 12mm acts as a pivot or spacer, ensuring accurate alignment of moving parts like gears, bearings, and linkages, which reduces wear and maintenance downtime. The coarse thread pitch and hex socket drive allow for quick, secure fastening in high-vibration environments, enhancing operational reliability. By integrating these features, this ISO 7379 certified fastener delivers long-term durability and performance in demanding engineering setups.

Specification Summary & Compliance
