Aerospace Steel Blind Rivet Flange

Aerospace: Rivets for aerospace applications include aluminum solid and blind rivets, as well as titanium, stainless steel, monel, inconel, and other exotic materials. Oversize repair rivets are available in solid and blind rivet forms as well. Rapid Rivet is Your Rivet Specialist. We are a Master Stocking Distributor of rivets, rivet nuts, threaded inserts, and tooling. We have a large and varied inventory to meet your needs. No automated telephone answering system here at Rapid Rivet. Speak directly to a knowledgeable salesperson who will assist you in selecting the rivet you require. We pride ourselves in our ability to give you a fast and competitive quotation. Many items are in stock, and next day delivery is available when requested. Most items are available with manufacturer’s certifications and test reports. We also can offer bar coding, unit packaging, and will set parts and shipments up for long-term release dates.

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.  

Blind:  (As in break-mandrel Blind Rivets, or “pop” rivets)  A blind rivet is a two-piece fastener consisting of a rivet body (sometimes called a “sleeve”) and the setting device called a mandrel. (or, stem or nail)  A blind rivet is used where access to a joint is limited to one side.  (You cannot “see” the other side of the joint, therefore it is “blind”)  A blind rivet is set by pulling the mandrel head into the rivet body, expanding the rivet body and causing it to flare against the reverse side.  As the head of the mandrel reaches the face of the blind side of the material, and at a pre-determined force, the mandrel will snap at the break point of the mandrel.  The rivet body forms a tight joint, the head of the mandrel remains encapsulated in the blind side, and the mandrel stem is ejected.

Blind Rivet:  Blind rivets can be set by relatively inexpensive tooling, which reduces costs. Structural blind rivets are also available for the aircraft industry and commercial uses. Structural blind rivets are employed where a solid rivet would normally by used, but where access to a joint is limited to one side.

Flange:  Large Flange Head.  In blind rivets, this style refers to a wide diameter protruding head, which is used when a large bearing surface is required.  Somewhat the same as a brazier head style in a solid rivet.
