Industrial fasteners can take many forms, for many different purposes. Here is a partial list of available industrial fasteners: anchors, bent bolts, cap screws, captive panel fasteners, drywall and deck screws, eye bolts, machine screws, nuts, cotter pins, retaining rings, rivets, screw driver insert bits, self clinching fasteners, self drilling screws, self tapping screws, sems, sockets, spring nuts, thread cutting screws, thread rolling screws, thumb-and-wing screws, washers, weld screws, and wood screws.
The sheer variety of industrial fasteners is overwhelming. Chances are, however, if you are in the market for a certain type of fastener, you know what you are looking for. Workers generally learn which screws to use for which jobs on their own, or with the assistance of their supervisors, peers, and training manuals. For a complete inventory on types and sizes, you can visit the commercial industrial fastener company American Fastener at their website. Even though it is a private, for-profit company, the website makes for a wonderful, general-knowledge store for the serious industrial fastener researcher. There you will find all fastener types and specifications, along with other helpful charts and diagrams. You can also find information on proper drill bit sizes and formats, heat-treated allow fasteners, a glossary of thread terminology, and more.
Industrial fasteners come in three main sizing standards: ASTM, SAE, and ISO (the American Society for Testing and Materials, the Society of Automotive Engineers, and the International Organization for Standards). Each of these standardization organizations recommends its own method of measuring and manufacturing fasteners. None are better than any of the others, but have varying applications and purposes, depending on what job you are working on. electrical connector types
