A J Bolts is a J-shaped bolt which can be used in a variety of applications. These bolts can be made from several different metals, and subjected to various treatments, depending on how and where they will be utilized. In a J bolt, the threading runs along the loner leg of the J. One could think of a J bolt as half a U bolt, since that is essentially what it is. The diameter of the bolt can be varied, as can the type of threading, and the angle and size of the hook at the base of the bolt. To attach something to a J bolt, threaded nuts and washers are utilized as needed. One common use of J bolts is as cast-in-place and masonry anchor bolts. Anchor bolts are used to affix various objects to concrete or masonry, and J bolts provide a great deal of support and stability, with the shape hooking the bolt in place so that it will not come loose.
