Glossary of terminology on topics related to nuts and bolts, threaded fasteners and tightening techniques.

EFFECTIVE DIAMETER - This is the diameter of an imaginary cylinder coaxial with the thread, which has equal metal and space widths. It is often referred to as pitch diameter. Sometimes referred to as the simple effective diameter to differentiate from the virtual effective diameter.

ELECTROLESS NICKEL - A relatively thin, hard coating that can be applied to threads and deposited uniformly. Bright metallic in appearance this coating has excellent resistance to wear and corrosion.

EMBEDMENT - Localized plastic deformation which occurs in the vicinity of clamped fasteners or in the fastener threads.

EXTERNAL FORCE OR LOAD - Forces exerted on a fastener as a result of an applied loading to the joint.

EXTERNAL THREAD - A screw thread which is formed on an external cylinder, such as on bolts, screws, studs

EFFECTIVE NUT DIAMETER -Twice the effective nut radius.




A process that can occur with the use of high strength steel fasteners in which crack initiation and growth occurs in the fastener at a comparatively low stress level as a result of interactions that occur with the environment.

Hydrogen is suspected of causing EAC in high strength steel fasteners, the hydrogen being produced as a result of chemical reactions (galvanic corrosion in a moist environment) or being present from a plating process that may have been applied to the fastener.

The radius from the centre of the nut to the point where the contact forces, generated when the nut is turned, can be considered to act.
