S-90265A115 M2 Shoulder Screws

Key Features & Benefits at a Glance

• Superior Corrosion Resistance: Made from 18-8 stainless steel, offering excellent durability and long-term performance in harsh or humid industrial environments.
• High Tensile & Shear Strength: With a tensile strength of 70,000 psi and minimum shear strength of 35,000 psi, it ensures reliable fastening under significant mechanical stress.
• Precise Shoulder Alignment: Features a 10mm shoulder length with tight tolerances, providing accurate component positioning and reducing assembly misalignment.
• Secure, Non-Slip Fastening: The knurled head texture and 2mm hex socket drive allow for firm tool grip and high-torque installation without stripping.
• Consistent Thread Performance: Class 5g6g thread fit ensures smooth engagement and reliable mating with nuts or threaded holes, minimizing play and vibration loosening.
• Environmental & Regulatory Compliance: Meets RoHS 3 and REACH standards, making it safe for use in regulated industries and electronics applications.
• Optimized for Metric Assemblies: M2 x 0.4mm coarse pitch thread provides quick installation and robust holding power in standard metric designs.

Professional Applications & Engineering Value

This M2 shoulder screw is engineered to address critical alignment and durability challenges in precision assemblies. The 18-8 stainless steel construction resists oxidation and chemical exposure, ideal for electronics, machinery, and automotive components where corrosion resistance is paramount. The 10mm shoulder acts as a precise locating dowel, ensuring accurate axial positioning of gears, bearings, or pulleys, while the hex socket drive and knurled head prevent cam-out during high-torque installation. With a Rockwell B55 hardness and 70,000 psi tensile strength, it withstands repetitive loads and vibrations, reducing maintenance needs in industrial shoulder screw applications such as robotics, conveyor systems, and precision instruments.

Specification Summary & Compliance

This precision shoulder screw features an M2 x 0.4mm coarse pitch thread with a Class 5g6g thread fit per metric standards, ensuring dimensional accuracy and interchangeability. The shoulder diameter tolerance is -0.072 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm, providing tight control for precision assemblies. It is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for environmentally conscious and global industrial markets.
