How to Read Aerospace Bolt Head Markings
The Boeing 747 is made of over six million parts. Half of these are aerospace fasteners. Fasteners, which play a critical role in the structural integrity and longevity of aircraft, include Aerospace Bolts, Aerospace Rivets, and Aerospace Screws & Studs. Bolts are used where high strength is the primary desired characteristic. Aerospace-quality bolts are typically made from titanium, stainless or corrosion resistant steel, or alloy steel.

If it does not have a marking, it is a commercial grade bolt. Aerospace bolt head markings will vary by manufacturer as each manufacturer has a trademarked head marking. All of Aerospace Manufacturing’s products will be head marked with our “AM” logo, identifying the products correlation to its world-class manufacturer.
