Bolts

 Carriage Bolts are ideal for fastening wood to metal. Alternatively, carriage bolts can also be used to fasten two pieces of wood together. Some specialty versions of carriage bolts allow for the effective fastening of two separate metal components.

 Bolts are  used to fasten and secure the faces of assemblies. They are threaded and come with a matching nut. Their purpose is to connect aligned unthreaded holes by being placed through the aligned holes and secured with the bolt's nut. 

 Lag Screws are generally used to connect heavy lumber and other materials that bear an intense load. They are different from other more common screws such as wood screws, sheet metal screws and self-drilling screws 

  Hex Flange Bolt is typically used when you need more surface area to distribute the load, such as in a threaded rod or an anchor bolt. 

 Sidewalk Bolts are commonly used to install plywood, metal, and fabric hurricane panels, hence the name Hurricane Bolt, however they are also used extensively in sheet metal fabrication, and with female threaded masonry anchors to anchor to concrete due to their flat, beveled head.
