Professional Applications & Engineering Value

This M6x1mm shoulder screw is engineered to solve critical alignment and pivot point challenges in industrial applications. The 18-8 stainless steel material provides excellent resistance to rust and corrosion, making it suitable for machinery, automotive assemblies, and electronic enclosures operating in demanding conditions. The 8mm shoulder diameter and 14mm shoulder length act as a precise locating dowel, ensuring components like gears, pulleys, and linkages are perfectly aligned, which minimizes vibration, reduces wear, and prevents assembly drift. The coarse thread and Class 5g6g thread fit facilitate quicker assembly and a secure hold. The socket head with a knurled texture allows for high-torque installation in confined spaces, a common requirement in compact precision equipment. This screw delivers reliable, long-term performance where dimensional accuracy and structural integrity are non-negotiable.

Specification Summary & Compliance

This shoulder screw conforms to ISO 7379 for dimensional consistency. The M6x1mm coarse metric thread features a Class 5g6g tolerance for a secure fit. The shoulder diameter tolerance is -0.072 to -0.01 mm, and the shoulder length tolerance is 0 to 0.25 mm, ensuring high precision. The manufacturing and material composition are RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, adhering to international environmental and safety regulations.
