Professional Applications & Engineering Value
This black-oxide steel thumb screw delivers exceptional value in applications requiring frequent adjustments or tool-free maintenance. The knurled head texture provides superior tactile grip even with oily hands or gloves, reducing assembly time in production lines and electronic enclosures. Its fully threaded M4 metric design with coarse pitch enables quick installation and high resistance to loosening under vibration, making it ideal for machinery panels, automotive components, and test equipment. The raised round-head profile offers comfortable thumb pressure distribution, while the black-oxide coating adds corrosion protection in humid or chemically exposed environments. Engineered to DIN 464 standards, this screw ensures reliable performance in precision assemblies where dimensional consistency is critical.
Specification Summary & Compliance
This M4 x 0.7 mm thumb screw features a Class 6g thread fit per ISO metric standards, ensuring precise tolerance for consistent engagement. The 12 mm length and fully threaded construction provide uniform clamping force across applications. Manufacturing complies with DIN 464 specifications for dimensional accuracy and mechanical properties. The product is fully RoHS 3 (2015/863/EU) compliant and REACH (EC 1907/2006) compliant, meeting stringent environmental regulations for hazardous substance restrictions.
