S-91273A842 M10 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction and black oxide finish, ideal for harsh industrial environments.
• High mechanical strength offering 70,000 psi tensile strength and 35,000 psi shear strength for reliable load-bearing in demanding applications.
• Precise alignment and smooth rotation due to the standard shoulder fit and controlled shoulder diameter tolerance (-0.04 to -0.01 mm).
• Secure, non-slip installation enabled by the knurled head and 5 mm hex drive, ensuring firm tool grip during tightening.
• Accurate and durable thread engagement with Class 5g6g thread fit and coarse M10x1.5 mm thread, providing consistent performance.
• Rockwell B55 hardness ensures excellent wear resistance and long service life under repetitive use.
• Compliance with environmental regulations, being RoHS 3 and REACH compliant, meeting global standards for safe use.

Professional Applications & Engineering Value

This M10 shoulder screw is engineered to address critical alignment and durability challenges in industrial machinery. The 50mm shoulder length with minimal tolerance (0 to 0.25 mm) ensures precise component positioning, reducing wear and misalignment in assemblies like rotating shafts, gears, and linkages. Made from 18-8 stainless steel and finished with black oxide, it resists corrosion in moist or chemical-exposed settings, extending equipment lifespan. The coarse metric thread and Class 5g6g fit facilitate quick, secure fastening in high-vibration environments, while the socket head with knurled texture allows for easy installation in confined spaces. Ideal for automation, automotive, and heavy equipment, this screw delivers reliable performance where precision and strength are paramount.

Specification Summary & Compliance

This shoulder screw adheres to metric system standards with an M10x1.5 mm coarse thread and Class 5g6g thread fit for consistent dimensional accuracy. The shoulder diameter tolerance is -0.04 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm, ensuring precise engineering fits. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free of hazardous substances and suitable for global industrial applications.
