Since nearly all fasteners are heat treated, it is useful to understand the types of heat treatments used in the fastener industry.

L&L Special Furnace Co. Inc. manufactured a highly uniform box furnace that hardens tool steel used to manufacture decking fasteners and supports.

Fasteners are used in every industry. In order to achieve the necessary high strength, durability and corrosion resistance, high-performance fasteners must be heat treated.

Hydrogen embrittlement of fasteners is a result of electrochemical surface treatments whereby hydrogen (in atomic form) enters the lattice of the steel and causes microcracks in the structure, followed by mechanical failure.

The Fastenal Company, a well-known name in the heat treatment industry, has invested more than $7 million in the past two years to bring secondary processes in-house, including a heat-treat department.

After fasteners are manufactured, coatings are often applied to provide enhanced properties.

The effect of hydrogen on aluminum alloys can manifest itself in a phenomenon known as high-temperature oxidation (HTO), also known as high-temperature deterioration (HTD).

All fasteners undergo heat processing during their manufacture, and many undergo multiple heating processes.

Alcoa Fastening Systems (AFS), a unit of Alcoa, signed a strategic technology and commercial cooperation agreement with Commercial Aircraft of China Ltd. (COMAC).
