S-90265A529 M2 Shoulder Screws

Key Features & Benefits at a Glance

• Enhanced Durability & Corrosion Resistance: Crafted from 18-8 Stainless Steel for long-lasting performance in harsh industrial environments.
• Superior Wear Resistance & Reduced Glare: The Black Oxide finish provides added surface protection and a non-reflective appearance.
• High Tensile & Shear Strength: With a 70,000 psi tensile strength and 45,000 psi minimum shear strength, this screw reliably handles high-stress applications.
• Precise Component Alignment & Pivoting: The 3mm shoulder diameter and 12mm shoulder length ensure accurate location and smooth rotation of assembled parts.
• Secure, Non-Slip Fastening: The knurled head and 2mm hex socket drive offer excellent grip and torque transmission, preventing tool slippage.
• Guaranteed Thread Compatibility: Class 5g6g thread fit ensures consistent, reliable engagement with standard metric nuts and tapped holes.
• Compliance with Global Standards: Meets RoHS 3 and REACH regulations, ensuring environmental and safety compliance for international markets.

Professional Applications & Engineering Value

This M2 shoulder screw is engineered to solve critical alignment and pivoting challenges in precision assemblies. The 12mm shoulder length acts as a precise locating diameter, eliminating the need for additional spacers or bushings and reducing component count. Manufactured from 18-8 Stainless Steel with a Rockwell B83 hardness, it resists corrosion and maintains integrity under load. The black oxide finish not only enhances corrosion resistance but also minimizes light reflection in sensitive optical or electronic equipment. The knurled head provides superior grip for manual adjustments, while the socket head design allows for high torque application in confined spaces, making it ideal for robotics, machinery, and automotive sub-assemblies where reliability and precision are non-negotiable.

Specification Summary & Compliance

This precision metric shoulder screw features an M2 x 0.4mm coarse thread with a Class 5g6g thread fit for standard tolerance. The shoulder diameter is held to a tight tolerance of -0.072 to -0.01 mm, and the shoulder length to 0 to 0.25 mm, ensuring high dimensional accuracy. It is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for use in regulated industries and global supply chains.
