Right-hand thread (positive thread): When rotated clockwise, the nut moves along the tightening direction of the bolt. It is the most commonly used type of thread in industrial production and daily life (e.g., household screws and furniture bolts are all right-hand threads).
Left-hand thread (reverse thread): Tighten by turning counterclockwise, commonly used in scenarios where loosening due to equipment reversal needs to be prevented (e.g., left-side bicycle pedals, anti-loosening nuts on certain rotating equipment).
Simple Differentiation Method:
Place the bolt vertically with the threads sloping from the lower left to the upper right → right-hand (standard thread)
The thread is inclined from the lower right to the upper left → Left-hand (reverse thread)
【Application Scenarios】
✅ Industrial precision drive systems
✅ CNC machine feed screw upgrades
✅ Automation linear motion modules
✅ 3D printer Z-axis mechanisms
✅ Heavy equipment maintenance
