Professional Applications & Engineering Value

This M3 thumb screw delivers exceptional value in applications requiring frequent adjustments or tool-free maintenance. The 18-8 stainless steel material provides inherent corrosion resistance, making it suitable for electronics enclosures, medical devices, and outdoor equipment where moisture exposure is a concern. The knurled head with flared collar design prevents slipping during hand-tightening, reducing installation time and minimizing damage to components. With its Class 6g thread fit and coarse 0.5 mm pitch, this fully threaded screw ensures rapid assembly and reliable performance in vibration-prone environments, while the 80,000 psi tensile strength guarantees it withstands repeated use without failure.

Specification Summary & Compliance

This thumb screw features M3 x 0.5 mm coarse pitch metric threading with Class 6g thread fit per ISO standards, ensuring dimensional accuracy and compatibility. The fully threaded 24 mm length provides consistent engagement, while the round head with flared collar (6 mm diameter, 3.5 mm height) offers stable seating. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted substances for safe industrial and commercial use.
