FAQ（常见问题）

Q1: What is the advantage of left-hand thread bolts?
A1: Left-hand threads tighten counterclockwise, preventing loosening in applications where rotational forces could unscrew standard right-hand bolts.

Q2: Can these bolts handle heavy loads?
A2: Yes, Grade 12.9 steel provides exceptional tensile strength, making them suitable for high-stress applications.

Q3: 这些与标准螺母兼容吗？
A3: Use matching left-hand threaded nuts of the same metric size to ensure proper fastening.

Q4: How should I properly install these hex bolts?
A4: Use a suitable wrench or torque wrench, turning counterclockwise to tighten. Follow recommended torque values to prevent over-tightening.
