Professional Applications & Engineering Value
This M3 thumb screw delivers critical engineering advantages for panel assembly applications where frequent access and reliability are paramount. The 18-8 stainless steel construction provides inherent corrosion resistance, eliminating degradation in humid or chemically aggressive environments. The knurled round head offers exceptional tactile grip for tool-free operation, while the partial threading and captive panel screw design ensure components remain securely fastened during vibration-intensive operation. The coarse metric thread (M3 x 0.5 mm) enables rapid engagement and disengagement, significantly reducing maintenance downtime in electronic enclosures, industrial control panels, and instrumentation housings where repeated access is necessary.
Specification Summary & Compliance
This metric thumb screw features M3 x 0.5 mm coarse threading with standard metric tolerances, 22 mm overall length with partial threading, and 6.5 mm knurled head diameter. Manufactured to ASTM A581 specifications for consistent quality and performance. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in global industrial and electronic applications.
