S-90265A241 M5 ISO 7379 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 Stainless Steel construction, ideal for harsh environments and reducing long-term replacement costs.
• Precise component alignment and pivot points ensured by the 16mm shoulder with controlled diameter tolerance for smooth bearing or bushing fit.
• High mechanical strength and durability from a Rockwell B83 hardness and 70,000 psi tensile strength, preventing failure under load.
• Secure, tamper-resistant installation via the internal hex socket drive, allowing for high torque application in confined spaces.
• Reliable thread engagement with a Class 5g6g fit coarse M5x0.8 thread, facilitating faster assembly and reducing cross-threading risks.
• Compliance with international standards including ISO 7379, ensuring interchangeability and consistent quality for global engineering projects.
• Environmentally responsible manufacturing meeting RoHS 3 and REACH regulations, making it suitable for regulated industries and green initiatives.

Professional Applications & Engineering Value

This M5 shoulder screw is engineered to solve critical alignment and wear challenges in mechanical assemblies. The 18-8 Stainless Steel material provides excellent resistance to rust and corrosion, which is vital for machinery in humid or chemically aggressive settings like food processing, marine, or outdoor equipment. The unthreaded 16mm shoulder acts as a precise datum for locating gears, pulleys, or linkages, minimizing eccentric movement and bearing wear. The hex socket drive offers a flush profile and high torque capability, essential for compact designs in automation systems and precision instruments. Its Class 5g6g thread fit and coarse pitch ensure quick, robust fastening in high-vibration environments, reducing maintenance downtime and enhancing assembly line efficiency.

Specification Summary & Compliance

This shoulder screw features an M5x0.8 coarse thread with a Class 5g6g tolerance, a shoulder diameter of 6.5mm (tolerance: -0.072 to -0.01 mm), and a shoulder length of 16mm (tolerance: 0 to 0.25 mm). It is manufactured in compliance with ISO 7379 and conforms to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring it is free of hazardous substances and suitable for use in regulated industrial applications.
