Professional Applications & Engineering Value
This M20 fully threaded hex screw is engineered to solve critical challenges in demanding industrial settings. Manufactured from 316 Stainless Steel, it delivers exceptional resistance to corrosion from chemicals, saltwater, and extreme weather, making it ideal for marine, chemical processing, and offshore applications. The coarse metric thread with a 2.5mm pitch ensures rapid assembly even in dirty or debris-prone environments, reducing installation time and labor costs. The fully threaded design provides continuous engagement, distributing load evenly and preventing joint loosening under vibration. Combined with its 100,000 psi tensile strength and external hex drive, this fastener offers reliable, long-term performance in structural frameworks, heavy machinery, and infrastructure projects where failure is not an option.
Specification Summary & Compliance
This hex head screw features M20x2.5 coarse thread with Class 6g tolerance and a length of 120mm, manufactured to ISO 4017 / DIN 933 dimensional standards. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring it is free from hazardous substances and suitable for global supply chains.
