Professional Applications & Engineering Value
This M6 pan head screw is engineered to address critical challenges in industrial assembly, such as loosening under vibration and exposure to corrosive elements. The combination of 18-8 stainless steel and a passivated finish provides exceptional resistance to rust and chemicals, making it suitable for machinery, automotive, and electrical enclosures in demanding environments. The integrated internal-tooth lock washer bites into the mating surface, preventing back-off and maintaining clamp load without the need for additional adhesives. With a Phillips drive and fully threaded metric design, it ensures quick, secure installation and reliable performance in applications where safety and durability are paramount.
Specification Summary & Compliance
This screw features M6 x 1 mm coarse threads with a Class 6g tolerance for precise fit, and is fully threaded over a 25 mm length. It complies with ASME B18.13.1M for dimensional consistency, and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring it is free of hazardous substances and safe for various industrial uses.
