Professional Applications & Engineering Value
This M8 thumb screw delivers exceptional value in applications requiring frequent tool-less access while maintaining structural integrity. The 18-8 stainless steel composition provides reliable corrosion resistance for electronics enclosures, industrial machinery panels, and outdoor equipment where environmental exposure is a concern. The deep knurled head texture ensures positive grip under challenging conditions, while the metric coarse threading (M8x1.25mm) enables rapid installation and removal in maintenance-heavy environments. With fully threaded construction and Class 6g fit, these screws offer consistent performance in precision assemblies, reducing the risk of stripped threads and ensuring repeatable fastening in manufacturing, automation, and instrumentation applications.
Specification Summary & Compliance
This thumb screw features M8x1.25mm coarse threading with Class 6g thread fit per metric standards, ensuring precise dimensional accuracy. The 30mm knurled round head with 6mm height and 16mm collar diameter provides optimal ergonomics. Manufactured from 18-8 stainless steel with Rockwell B83 hardness and 80,000 psi tensile strength. Fully compliant with DIN 464 specifications, RoHS 3 (2015/863/EU), and REACH (EC 1907/2006) environmental standards for restricted substance control.
