Elevator bolts are a type of fastener that is used to secure an object to another object. Generally, these bolts are screwed into their mounting surfaces and tightened with a wrench. Elevator bolts may also be used in conjunction with nuts and washers to form a more durable attachment than just tightening the bolt alone. To tighten an elevator bolt, the screwdriver or wrench should be inserted into the head of the bolt and turned so that it rotates tightly.
