S-90269A115 M2 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh environments and extended service life
• Precise component alignment ensured by the 3mm shoulder diameter, reducing assembly errors and improving product quality
• High mechanical strength with 70,000 psi tensile strength and Rockwell B79 hardness for reliable performance under load
• Secure, non-slip fastening provided by the knurled hex socket head, allowing for high-torque installation with a standard 2mm hex key
• Consistent thread engagement with Class 5g6g metric coarse thread (M2 x 0.4mm), ensuring reliable clamping force and vibration resistance
• Dimensional stability with tight shoulder diameter and length tolerances, guaranteeing repeatable positioning in precision assemblies
• Compliance with global regulations including RoHS 3 and REACH, making it suitable for international supply chains and sensitive applications

Professional Applications & Engineering Value

This M2 shoulder screw is engineered to address critical alignment and durability challenges in industrial applications. The 316 stainless steel material provides exceptional resistance to chemicals and moisture, preventing failure in demanding conditions like marine or chemical processing equipment. The integrated 10mm shoulder length acts as a precise pivot or spacer, eliminating the need for additional bushings and reducing assembly complexity in machinery, automation systems, and electronic enclosures. The hex socket drive with a knurled texture ensures a secure grip, minimizing tool slippage during high-torque installation. With its Class 5g6g thread fit and coarse 0.4mm pitch, it offers quick assembly and reliable retention in precision engineering projects, from robotics to optical instruments, where component misalignment is not an option.

Specification Summary & Compliance

This precision shoulder screw features a Metric M2 x 0.4mm coarse thread with a Class 5g6g thread fit per ISO standards, ensuring dimensional accuracy and interchangeability. The shoulder diameter is manufactured to a tight tolerance of -0.072 to -0.01 mm, and the shoulder length tolerance is 0 to 0.25 mm, guaranteeing consistent performance. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, affirming its suitability for use in environmentally conscious and regulated industries.
