Self-threading bolt, 5/16inch x 1inch
This self-threading bolt, 5/16inch x 1inch is commonly used to fasten the shurco rope anchor, #SL1701355. This bolt can be bought in bulk quantities. You can use it for other odd jobs as it is a standard 5/16 bolt; however, it has the upper hand over standard bolts when dealing with aluminum. Its self-threading ability allows you to simply drill a 17/64″ hole and run the bolt into the material. This eliminates the need for a nut on the inside. For this reason, the 5/16 x 1 self-threading bolt is obviously useful for bolting into a tube or any other surface where you cannot or do not wish to have a nut and bolt end exposed.
