S-91273A443 M10 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 Stainless Steel construction, ideal for harsh industrial environments and outdoor applications.
• High mechanical strength and durability with a tensile strength of 70,000 psi and Rockwell B55 hardness for reliable performance under heavy loads.
• Precise component alignment and spacing enabled by the 10mm diameter shoulder with controlled tolerances, reducing assembly errors.
• Secure and non-slip installation thanks to the knurled head and 5mm hex socket drive, allowing for high-torque application.
• Wide compatibility and easy assembly with a standard M10x1.5mm coarse metric thread and Class 5g6g fit, ensuring consistent engagement.
• Enhanced operational safety and regulatory compliance by meeting RoHS 3 and REACH standards, suitable for sensitive and regulated industries.
• Versatile shaft and bearing surface with a 16mm thread length and 10mm shoulder length, accommodating various mechanical designs.

Professional Applications & Engineering Value

This M10 shoulder screw is engineered to address critical alignment and rotational stability challenges in precision assemblies. The 18-8 Stainless Steel material provides excellent resistance to rust and chemical exposure, making it suitable for food processing, marine, and chemical equipment. The 10mm shoulder diameter acts as a precise pivot or locating dowel, preventing lateral movement in linkages, gears, and rotating parts. Combined with the Class 5g6g thread fit and coarse thread pitch, it ensures rapid assembly and reliable clamping force in high-vibration environments like machinery, automotive jigs, and conveyor systems. The knurled head and hex socket drive further enhance grip and torque transmission, reducing the risk of tool slippage during installation.

Specification Summary & Compliance

This shoulder screw features a metric M10x1.5mm coarse thread with a Class 5g6g thread fit for standard tolerance. The shoulder diameter tolerance is -0.04 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm, ensuring precise dimensional control. Manufactured in accordance with standard metric specifications, it is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting stringent environmental and safety regulations for industrial components.
