S-90270A685 M6 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments and extended service life.
• Precise component alignment ensured by the 8mm shoulder diameter with a tight tolerance fit, minimizing play and vibration.
• High-strength fastening with a tensile strength of 70,000 psi and Rockwell B55 hardness for reliable performance under load.
• Easy installation and removal with a standard socket head, providing a secure drive and reducing the risk of tool slippage.
• Wide compatibility with M6x1 coarse metric threads and Class 6g fit, ensuring easy integration into existing metric assemblies.
• Environmental compliance meeting RoHS 3 and REACH standards, making it suitable for regulated industries and global supply chains.

Professional Applications & Engineering Value

This M6 shoulder screw is engineered to solve critical alignment and durability challenges in industrial applications. The 18-8 stainless steel material provides excellent resistance to rust and corrosion, which is vital for machinery operating in moist or chemically aggressive settings. The precision shoulder, with its controlled diameter and length tolerances, acts as a pivot or axle, ensuring precise location of components like gears, pulleys, and linkages without the need for additional bushings or spacers. This eliminates misalignment, reduces wear, and simplifies assembly. The combination of a socket head and right-hand coarse thread (M6x1) allows for efficient installation in high-volume production or maintenance scenarios, providing a robust and reliable fastening solution that maintains integrity under dynamic loads.

Specification Summary & Compliance

This precision shoulder screw features an M6x1 metric thread with a Class 6g thread fit. The shoulder has a diameter of 8mm with a tolerance of -0.025 to 0 mm and a length of 8mm with a tolerance of 0 to 0.05 mm, ensuring a precise fit. It is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations.
