S-90265A404 M12 ISO 7379 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 Stainless Steel construction, ideal for harsh environments and extended service life.
• Precise component alignment and smooth rotation thanks to the 60mm shoulder with controlled diameter tolerance for reliable bearing surfaces.
• High-strength performance under load with a tensile strength of 70,000 psi and a minimum shear strength of 45,000 psi for demanding applications.
• Secure and easy installation using a standard 8 mm hex socket drive and a knurled head for improved grip and torque application.
• Reliable and consistent thread engagement ensured by the M12x1.75 coarse thread with Class 5g6g fit for vibration resistance.
• Enhanced durability and wear resistance provided by a Rockwell B83 hardness rating.
• Global compliance and safety meeting ISO 7379 standards and being RoHS 3 & REACH compliant for use in regulated industries.

Professional Applications & Engineering Value

This M12 shoulder screw is engineered to solve critical alignment and pivot point challenges in industrial machinery. The 18-8 Stainless Steel material offers excellent resistance to rust and corrosion, which is vital in environments exposed to moisture or chemicals. The 60mm shoulder length provides a precise, unthreaded bearing surface that ensures accurate positioning of moving parts like gears, levers, and pulleys, reducing wear and preventing misalignment. The hex socket drive and knurled head texture allow for high-torque installation in confined spaces, making it a reliable choice for assembly lines, automotive jigs, and conveyor systems where precision shoulder screws are essential for maintaining operational integrity and reducing maintenance downtime.

Specification Summary & Compliance

This metric shoulder screw features an M12x1.75 coarse thread with a Class 5g6g thread fit for standard tolerance applications. The shoulder diameter is 16 mm with a tolerance of -0.072 to -0.01 mm, and the shoulder length is 60 mm with a tolerance of 0 to 0.25 mm, ensuring high dimensional accuracy. Manufactured in compliance with ISO 7379 specifications, it also conforms to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, guaranteeing safety and sustainability in industrial use.
