The elevator bolts are designed for heavy-duty applications to fasten conveyor belts and other mechanical components. The head of such bolts is large, flat, and countersunk; the neck is square-shaped to lock in place and not allow rotation during installation. Usually manufactured from high-tensile materials, elevator bolts will ensure tight bonding even under great mechanical tension. https://www.dalloyedbolts.com/elevator-bolts-manufacturers-suppliers-stockists-exporters.html
