Fastening nuts on threaded rod can be a struggle due to the confined space and obstructions around the rod. Lateral movement is limited. On long sections of threaded rod, traditional nut drivers bottom out so you can only get the nut so far up the rod. Klein’s Heavy-Duty Nut Driver feature a through-handle, completely hollow shaft to allow for nutdriving on unlimited bolt lengths. Wrench assist provides greater torque while the magnetic tips will grab any nut appropriately.

由于受限的空间和杆周围的障碍物，螺纹杆上的紧固螺母可能是一种挣扎。横向移动是有限的。在螺纹杆的长部分上，传统的螺母驱动器从底部伸出，因此您只能将螺母推到杆上。Klein的重型螺母驱动器具有一个贯通手柄，完全空心的轴，可以在 螺栓长度上进行螺母驱动。扳手辅助提供更大的扭矩，而磁性尖端将适当地抓住任何螺母。
