Does the length measurement of a bolt include the head? In most cases, when specifying the length of a headed bolt, the thickness of the bolt head is not included. For instance, if you were to order a ¾” x 24” hex head bolt, the bolt would measure 24” from under the head.
How much weight can 3 8 hanger bolt hold? ›A 3/8-inch bolt of this type is rated to 7,000 pounds in 6,000 psi concrete (basically granite) and 4,000 pounds in 2,000 psi concrete (hard sandstone). This is roughly the breaking strength range of carabiners and much higher than any rope's maximum possible impact force.
