S-90269A618 M6 ISO 7379 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh industrial environments and extended service life.
• Enhanced durability and wear resistance from the black oxide finish, providing added protection against abrasion and reducing galling.
• High mechanical strength with 70,000 psi tensile and 35,000 psi shear strength, ensuring reliable performance under heavy loads and stress.
• Precise alignment and smooth rotation thanks to the accurately machined shoulder with a diameter of 8 mm and length of 55 mm, minimizing part movement.
• Secure and easy installation using a standard 4 mm hex drive and knurled head, offering excellent grip and torque transmission.
• Consistent thread engagement with Class 5g6g fit and coarse M6x1 mm right-hand threads, facilitating quick assembly and reducing cross-threading risks.
• Compliance with international standards including ISO 7379, RoHS 3, and REACH, ensuring safety, quality, and environmental responsibility.

Professional Applications & Engineering Value

This M6 shoulder screw is engineered to address critical alignment and load-bearing challenges in precision assemblies. Made from 316 stainless steel and finished with black oxide, it resists corrosion in demanding settings like chemical processing, marine equipment, and food machinery. The knurled head and hex drive enable secure handling, while the precisely toleranced shoulder (diameter 8 mm, length 55 mm) ensures components are accurately positioned, reducing wear and vibration. With a Rockwell B79 hardness and high tensile strength, it supports robust performance in industrial applications such as pivots, gears, and rotating mechanisms, offering long-term reliability and minimal maintenance.

Specification Summary & Compliance

This shoulder screw features M6x1 mm coarse threads with a Class 5g6g thread fit for precise engagement, and shoulder dimensions include a diameter of 8 mm (tolerance: -0.072 to -0.01 mm) and length of 55 mm (tolerance: 0 to 0.25 mm). It is manufactured to meet ISO 7379 specifications and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) standards, ensuring environmental safety and regulatory adherence for global industrial use.
