These hard-to-find Left-Hand taps and dies can be indispensible for fabricating or repairing parts that have reversed screw threads, such as linkages or suspension components.
The left-hand taps and dies are mirror image designs of right-hand taps and dies .
Left hand threads when required twist in a counter clockwise direction.
Screws are often tightened clockwise, which is why most threads are right-handed. Left-hand cutting threads are used if the screw could loosen due to stress.
Left handed threads are used to fasten rotating parts that rotate in anticlockwise direction and the motion tends to tighten the fastener.
