Steel / Zinc Elevator Bolts at Fastener SuperStore
August 31, 2018
Fastener SuperStore carries steel / zinc elevator bolts in the common diameter sizes of 1/4-20, 5/16-18 and 3/8-16. Lengths are available from 3/4" up to 3".
Elevator bolts are similar to carriage bolts in that they are low profile and feature a square protrusion on the bottom side of the head. The square neck allows these bolts to stay in place while tightening or loosening from the nut side when inserted into a square hole.
They differ from carriage bolts by offering a flat surface on the top of the head and a wider bearing surface. The wider bearing surface makes them a good option for vertical fastening, and for use in conveyor systems, such as their namesake.
These parts offer a yield strength of 36,000 psi and a tensile strength of 54,000 psi minimum.
The length of an elevator bolt is measured from the top of the head to the end of the bolt, and the thread length is two times the diameter size, plus .25", at a minimum.
