Professional Applications & Engineering Value
This M3 left-hand thread screw is precision-engineered from 18-8 stainless steel to address critical needs in industrial settings where reverse threading prevents loosening under counter-clockwise motion. Its coarse 0.5 mm pitch and Class 6g thread fit ensure quick assembly and high resistance to vibration, making it suitable for machinery, automotive components, and rotating equipment. The hex drive allows for high-torque application without slippage, while the rounded button head offers a flush finish that minimizes protrusion in tight spaces. Fully threaded for maximum grip, this metric left-hand fastener delivers reliable performance in demanding applications, from conveyor systems to specialized tools.
Specification Summary & Compliance
This screw adheres to metric thread standards with M3 x 0.5 mm coarse pitch and Class 6g thread fit for precise dimensional accuracy.
