Professional Applications & Engineering Value

This precision shoulder screw addresses critical alignment challenges in industrial machinery and precision equipment. The 360 brass construction provides excellent corrosion resistance while maintaining the mechanical strength required for rotational components and bearing surfaces. The exact shoulder dimensions with tight tolerances (±0.025mm diameter, +0.05mm length) ensure perfect component positioning in assemblies, eliminating misalignment issues that can lead to premature wear. The M8x1.25mm coarse thread with Class 6g fit facilitates quick installation while maintaining secure fastening in automation equipment, precision instruments, and rotating assemblies. The socket head hex drive allows for high-torque installation in confined spaces, making it ideal for maintenance-intensive applications where reliability and repeatable performance are paramount.

Specification Summary & Compliance

Manufactured to precise metric specifications with Class 6g thread tolerance and shoulder dimensions maintaining tight tolerances (diameter: -0.025 to 0mm, length: 0 to +0.05mm). The screw features M8x1.25mm coarse threads with right-hand orientation and standard socket head profile. Compliant with RoHS 3 (2015/863/EU) under exemption 6(c) for lead in copper alloys and REACH (EC 1907/2006) regulations, ensuring environmental responsibility while delivering reliable mechanical performance with 40,000 psi tensile strength and Rockwell B55 hardness characteristics.
