The torque required to effect reverse rotation when a pre-stressed threaded assembly is loosened.

A specialist thread form based upon the Whitworth thread and consisting of 26 threads per inch whatever the thread diameter.

British Standard Fine. A thread form based upon the British Standard Whitworth form but with a finer thread (more threads per inch for a given diameter). This thread form was first introduced in 1908, the thread form is specified in BS 84: 1956.

THREAD HEIGHT - This is the distance between the minor and major diameters of the thread measured radially.


THREAD RUNOUT - The portion at the end of a threaded shank which is not cut or rolled to full depth, but which provides a transition between full depth threads and the fastener shank or head.

THREADLOCKER - Can be a term used for a number of vibration resistant products but is now usually reserved for threadlocking adhesives. Specifically, a liquid anaerobic adhesive applied to nut or bolt thread, once hardened it fills the inner spaces between the threads to produce a solid plastic of a known shear strength.

TIN/ZINC ALLOY ELECTROPLATING - Tin/zinc alloy coatings (typically 70% tin and 30% zinc) are applied to threaded fasteners to provide a corrosion resistant coating. One of the advantages of such coatings is that bimetallic corrosion will not occur when placed into contact with such metals as aluminium or steel.

THREAD ROOT - The thread root is the bottom of the thread, on external threads the roots are usually rounded so that fatigue performance is improved.
