• Secure, high-torque installation facilitated by the 6mm hex socket drive and knurled head, preventing tool slippage.
• Accurate and reliable thread engagement due to the M10x1.5 coarse pitch thread with Class 5g6g fit, ensuring consistent fastening.
• Compliance with major environmental regulations including RoHS 3 and REACH, making it suitable for global supply chains.
• Durability and wear resistance from the hardened stainless steel material, maintaining integrity under repeated use.

Professional Applications & Engineering Value

This M10 shoulder screw is engineered to address critical assembly challenges in precision machinery, automation systems, and fixture design. The 18-8 stainless steel material provides excellent resistance to rust and oxidation, which is vital for equipment operating in humid or corrosive conditions. The hex socket head with a knurled texture allows for high-torque tightening in confined spaces, minimizing the risk of cam-out. The unthreaded shoulder acts as a precise pivot, bearing surface, or spacer, preventing radial movement and reducing wear on mating parts. This design is essential for maintaining alignment in rotating assemblies, such as in conveyor systems, robotic arms, and printing equipment, ensuring smooth operation and reducing maintenance downtime. The coarse pitch metric thread enables quick assembly and disassembly, which is crucial for production lines requiring frequent adjustments.
