Professional Applications & Engineering Value
This M3 pan head screw is engineered to address common challenges in assembly and maintenance, such as vibration-induced loosening and corrosion in industrial settings. The combination of 18-8 stainless steel and a passivated finish significantly enhances durability against moisture, chemicals, and oxidation, making it suitable for electronics, machinery, and outdoor equipment. The integrated internal-tooth lock washer bites into the bearing surface, providing reliable locking without needing additional components, which streamlines inventory and reduces installation time. With a coarse thread and Phillips drive, it ensures quick, secure fastening in metals and plastics, supporting efficient production lines and reducing downtime in B2B technical procurement scenarios.
Specification Summary & Compliance
The screw features a metric M3 x 0.5mm thread with Class 6g tolerance for precise fit, fully threaded along a 25mm length. It complies with JIS B 1188-D specifications for dimensional accuracy and performance. Additionally, it meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and adherence to global standards for industrial fasteners.
