S-90263A118 M3 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh environments and extended service life.
• Enhanced durability and strength from Rockwell B79 hardness and 70,000 psi tensile strength, preventing failure under load.
• Precise component alignment ensured by the exact 4mm shoulder diameter with tight tolerances for reliable assembly.
• Secure and efficient installation with a socket head and 2mm hex drive, allowing for high torque application in confined spaces.
• Reliable thread engagement due to the Class 6g thread fit and coarse M3x0.5 metric thread, reducing cross-threading risks.
• Long-term material integrity from the passivated finish, which improves resistance to corrosion and wear.
• Compliance with global environmental standards including RoHS 3 and REACH, ensuring safe and sustainable use in regulated industries.

Professional Applications & Engineering Value

This M3 shoulder screw is engineered to address critical alignment and durability challenges in industrial applications. Made from 316 stainless steel and featuring a passivated finish, it resists corrosion in demanding settings like chemical processing or marine environments. The precise shoulder diameter and Class 6g thread fit ensure accurate positioning and secure fastening in assemblies such as machinery, pivots, and electronic enclosures, minimizing misalignment and vibration-related failures. Its socket head with hex drive allows for easy installation in tight spaces, enhancing maintenance efficiency while the high tensile strength supports heavy-duty operational demands, providing long-term reliability and reduced downtime.

Specification Summary & Compliance

This shoulder screw adheres to metric system standards with an M3x0.5 coarse thread and Class 6g thread fit for precise tolerance. The shoulder diameter is controlled to -0.025 to 0 mm tolerance, and shoulder length to 0 to 0.05 mm, ensuring exact alignment. It is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for use in environments requiring strict environmental and safety standards.
