- Precise alignment and spacing enabled by the 5mm diameter shoulder with controlled tolerances, reducing component wear.
- Efficient torque transmission via the 2.5mm hex socket drive, minimizing slippage and tool wear during installation.
- Durable thread engagement with Class 5g6g metric coarse threads (M3 x 0.5mm pitch), ensuring secure fastening in dynamic conditions.
- Knurled head texture for improved grip during manual handling, enhancing assembly safety and efficiency.
- Globally compliant design meeting ISO 7379 standards and RoHS 3/REACH regulations for unrestricted international use.
Professional Applications & Engineering Value
This M3 shoulder screw is engineered to address critical alignment and durability challenges in precision industrial assemblies. The 18-8 Stainless Steel material provides excellent corrosion resistance, making it suitable for machinery exposed to moisture, chemicals, or outdoor elements. The 5mm shoulder diameter and 20mm shoulder length act as a precise locating dowel, maintaining accurate part positioning in rotating equipment, pivoting joints, and metric-based automation systems. Combined with the hex socket drive, it ensures high torque application without damaging the head, reducing assembly errors and maintenance downtime in high-vibration environments like robotics, conveyor systems, and electronic enclosures.
Specification Summary & Compliance
The screw features a Class 5g6g thread fit per metric standards, with shoulder diameter tolerance of -0.072 to -0.01 mm and shoulder length tolerance of 0 to 0.25 mm for consistent dimensional accuracy. Manufacturing and material specifications comply with ISO 7379, and the product is verified as RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring adherence to international environmental and safety regulations.
