Professional Applications & Engineering Value

Engineered for precision, this M1.6 shoulder screw addresses critical alignment challenges in compact assemblies. The 18-8 stainless steel construction resists corrosion from moisture, chemicals, and temperature fluctuations, making it ideal for electronics, medical devices, and instrumentation. The precise shoulder (2mm diameter, 4mm length) acts as a built-in spacer, eliminating the need for additional components and reducing assembly time. With a Class 6g thread fit and coarse 0.35mm pitch, it ensures robust retention in high-vibration industrial applications, while the socket head design accommodates both slotted and hex tools for flexible installation. This screw is a reliable solution for maintaining dimensional accuracy and durability in precision engineering projects.

Specification Summary & Compliance

This shoulder screw adheres to metric system standards with a Class 6g thread fit for consistent performance. Shoulder diameter is maintained at 2mm with a tolerance of -0.025 to 0 mm, and shoulder length at 4mm with a tolerance of -0.15 to 0 mm, ensuring precise fit in demanding applications. It is manufactured to comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for environmentally conscious and regulated industries.
