The Fastener Specialist - Asia Bolts & Nuts Manufacturer of bolts and nuts, fasteners for export

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

A wrench, usually powered by electricity or air, in which repeated blows from little hammers are used to generate torque to tighten fasteners.

The torque applied to the fastener depends upon the time and the air pressure applied to the tool (for pneumatic wrenches). The torque applied by an impact wrench to a fastener is influenced by the joint stiffness.


The point in space that an eccentrically shear loaded joint rotates about.

The deformation and the load sustained by an individual bolt in a bolt group is dependent upon the distance that the bolt is from the instantaneous centre.

The direction that the individual bolt force acts is perpendicular to a line joining that bolt to the instantaneous centre.

A term used to describe types of fasteners which are highly resistant to vibration loosening and/or removal. Some types have special thread forms.

INTERNAL THREAD - A screw thread which is formed in holes, such as in nuts.
