Stainless Steel Thumb Screw – M2 Size for Easy Fastening

Our Stainless Steel Thumb Screw – M2 Size redefines precision assembly for delicate projects like eyewear repair (0.79mm–0.83mm compatibility) and microelectronics mounting (see comparison below). Engineered with hexagonal flanges that prevent stripping under torque—ideal for repeated disassembly during device upgrades or prototyping phases.

Core Benefits
• Patented thumb-grip design eliminates reliance on screwdrivers (saves 3+ minutes per hardware adjustment vs Phillips heads)
• A2-grade stainless steel resists saltwater corrosion better than zinc-plated variants by 85% (tested via ASTM B117)
• Laser-etched torque marks ensure consistent tightening pressure for LCD panel assemblies or dental equipment calibrations
