S-90269A224 M4 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh industrial environments and chemical exposure
• Exceptional mechanical strength with 70,000 psi tensile and 35,000 psi shear strength for reliable, high-load applications
• Precise component alignment enabled by the 5mm diameter shoulder with controlled tolerances, reducing assembly errors
• Secure, high-torque installation using the 2.5mm hex socket drive and knurled head for improved grip and reduced tool slippage
• Consistent thread engagement with Class 5g6g metric coarse threads (M4 x 0.7mm), ensuring reliable fastening and interchangeability
• Extended service life due to Rockwell B79 hardness, providing excellent wear resistance and durability
• Compliance with global standards including RoHS 3 and REACH, ensuring safety and environmental responsibility

Professional Applications & Engineering Value

This M4 shoulder screw is engineered to solve critical alignment and mounting challenges in precision assemblies. The 316 stainless steel material offers outstanding resistance to corrosion and oxidation, making it suitable for marine, chemical processing, and food-grade equipment. The 17mm shoulder length acts as a precise pivot or spacer, eliminating the need for additional bushings and reducing part count in machinery, automation systems, and rotating assemblies. The hex socket drive combined with the knurled head ensures secure, high-torque installation in confined spaces, preventing cam-out and damage to the fastener. Its coarse pitch thread (0.7mm) allows for quicker assembly and better performance in high-vibration environments, providing long-term reliability and reduced maintenance.

Specification Summary & Compliance

This shoulder screw features an M4 x 0.7mm coarse metric thread with Class 5g6g tolerance for precise fit. The shoulder diameter is 5 mm with a tolerance of -0.072 to -0.01 mm, and the shoulder length is 17 mm with a 0 to 0.25 mm tolerance. It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free of hazardous substances and suitable for regulated industrial applications.
