Steel:  (Also called Mild Steel and Low Carbon Steel)  This is the most common material for use in fasteners.  Steel is an alloy consisting of mostly iron, and a small percentage of carbon, (between 0.05 – 1.1%) It is the least expensive metal.  It is strong, has good workability, and can be produced in a wide variety of forms.  Its chief disadvantage is its susceptibility to corrosion (rust) in an un-plated, unprotected form.  Its other drawback, in aerospace applications, is that steel is about three times heavier than aluminum, while not offering any great advantage in strength.  Steel is magnetic.  Most mild steel used for rivets is heat treated, although there are some exceptions.  Most steel rivets will have some form of protective finish or coating when delivered from the mill (factory) to prevent corrosion.  Most steel for commercial applications will be plated zinc with a clear chromate.  Most steel for military or aerospace applications will be plated cadmium with a yellow chromate.  

A-S Series Stud:  A captive threaded stud, with a knurled body, made by AVK Industrial Products.

Threaded:   As in having a screw thread.  A screw thread is a ridge of uniform section in the form of a helix on the internal or external surface of a cylinder.  Internal threads are those in nuts, external threads are those found on bolts, screws, and studs.  Threaded components are the primary means of assembly for interchangeable or removable connections.  They are in a sense, the opposite of rivets, which are intended for permanent connections.  Screw threads give fasteners their ability to support and transfer loads.  Threaded components include Rivet Nuts, and Threaded Inserts.  These items are internally threaded components, like a nut, that can be permanently attached to another structure, to allow an external threaded component, such as a screw or bolt, to be installed.  

Threaded Inserts:  A threaded insert is a form of hardware that allows an internal or external threaded form to be installed in or through a body of work that in turn, can receive a bolt or nut, allowing two bodies to be joined together.  It is, in essence, a tubular rivet with internal threads.  It is also a blind rivet, in so much as access to the reverse side of the joint is not required to install the insert.  There are many different types of threaded inserts for use a wide variety of materials and applications.  Some types of threaded inserts install by use a special tool with a threaded stud that engages the threads of the insert and pulls upward.  This causes a portion of the body of the insert to deform, and expand against the reverse side of the material being fastened, forming a secure, permanent joint, that a screw or bolt can be attached to.  There are inserts with a stud, or external thread, in place of internal threads, that allow a nut to be installed.  Some types of threaded inserts swage into place.  In this type of threaded insert, a nut is held captive within a thin metal sleeve.  An installation tool engages the threaded portion of the nut, and draws the nut upward into the thin metal sleeve portion.  The nut portion is slightly wider than the sleeve, and as the nut is drawn into the sleeve, the sleeve is expanded outward against the reverse side of the work piece.  The nut portion jams into the sleeve, and is fixed into place.
