Cut Threading

Forming threads on a fastener by cutting away and actually removing the unneeded metal.…

Crevice Corrosion

Refers to joints and crevices in a fastener assembly where lack of oxygen caused by limited space or by surface grease prevents the passive film on stainless from forming.…

Creep Strength

A measure of the resistance of fasteners to stress under elevated temperatures. At higher temperatures, a fastener can change in dimension under the same load, and that is called creep. Creep can cause the loosening of fasteners as temperature increases.…

Cracks

A clean, crystalline fracture which passes through or across the grain boundaries without inclusion of foreign elements.…

Corrosion Resistance

The ability of a fastener or material to resist corrosion under specific conditions.  Coatings such as Hot Dipped Galvanizing are usually used to increase the level of corrosion resistance of anchor bolts.…

Core Harness

The resistance a fastener material has to being permanently deformed, measured at a spot deeper than the case depth.…

Cold Forming or Cold Heading or Cold Working

When fasteners are produced without heating or small heat below the recrystallization temperature (so the raw material bond of stainless remains unchanged) by pressing metal wire against various dies at high speed to form a fastener’s head or basic shape. …

Clamp Load

The total load across the joint interface in service. This may vary during service life.…

Chamfer

A slight rounding on the end of a fastener or the edges of a hex nut for ease of assembly or smoother appearance.…

Certificate of Compliance

A certification that a fastener meets the description or standard to which it was sold.…
