A combination lock has a pivoting bolt for engaging and disengaging a hasp. The hasp, which is disengaged from the bolt when the lock is on-combination, may be re-engaged with the bolt, even if the lock is off-combination. A first spring resiliently biases the bolt to an unlocked position. A second spring resiliently restrains movement of the bolt beyond a locked position in order to prevent disengagement of the hasp in response to application of a shock force to the lock.
