• High mechanical strength offering 70,000 psi tensile and 35,000 psi shear strength for demanding applications
• Secure, non-slip fastening with knurled socket head and 5mm hex drive preventing tool slippage
• Reliable thread engagement through Class 5g6g metric coarse threads (M8 x 1.25mm) for vibration resistance
• Global compliance assurance meeting ISO 7379 standards and RoHS 3/REACH environmental regulations
• Optimized durability with Rockwell B55 hardness balancing strength and machinability

Professional Applications & Engineering Value

This M8 shoulder screw delivers critical precision for industrial assembly where component alignment and rotational stability are paramount. The 18-8 stainless steel body resists corrosion in manufacturing, automotive, and machinery applications, while the 25mm shoulder length with controlled diameter tolerance acts as a precise pivot or spacer, eliminating bushing needs. The knurled socket head with 5mm hex drive ensures secure tool engagement in high-torque scenarios, and the Class 5g6g coarse thread facilitates quick assembly with maintained vibration resistance. Engineered to ISO 7379, it provides reliable performance in jigs, fixtures, and rotating assemblies.

Specification Summary & Compliance

Manufactured to ISO 7379 specifications with Class 5g6g thread fit and shoulder diameter tolerance of -0.072 to -0.01 mm. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety. The metric coarse thread (M8 x 1.25mm) and standardized shoulder dimensions guarantee interchangeability and precision in global engineering projects.
