Abstract
An anti-loosening bolt and nut assembly includes a bolt, a nut, and a locking member. A screw rod of the bolt has an upper portion formed with an external thread and a lower portion formed with a retaining section. The nut has an upper cavity formed with an internal thread and a lower portion formed with a locking section. The locking section has elasticity. When the locking section is pressed, the locking section is in tight fit with the retaining section. The locking member is sleeved on the locking section. The locking member has an inner cavity with a tapered section. When the locking member is rotated, the nut is moved axially for the tapered section to be pressed against the locking section tightly. The bolt and nut assembly provides an anti-loosening effect, has few parts, and can be operated easily in a narrow space.
