Professional Applications & Engineering Value
This M3.5 thumb screw is engineered from 18-8 stainless steel to solve common industrial challenges like corrosion-induced failure and the need for frequent maintenance. The fully threaded design with a Class 6g thread ensures maximum thread engagement and holding power, reducing the risk of loosening under vibration in machinery, electronic enclosures, and assembly jigs. The knurled head provides a non-slip surface, enabling secure hand-tightening without specialized tools, which is invaluable for field service, prototypes, and access panels. Its narrow profile and metric thread make it ideal for precision engineering applications where space is limited and reliable, tool-free fastening is required.
Specification Summary & Compliance
This thumb screw features an M3.5 x 0.6 mm coarse metric thread with a Class 6g tolerance for precise fit. It is fully threaded and measures 25 mm in length. The product is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for global markets.
