In an online post, WDS said there two types of handedness: right-handed thread and left-handed thread. Almost all products are right-handed. Components like nuts, bolts and screws are right-handed thread because of the direction of the movement when driving a screw into a bolt. Right-handed threaded components turn in a clockwise direction to tighten the part and then anti-clockwise to loosen the part.
The threads have sloped helical grooves responsible for the direction. Users can decide the thread type by seeing the grooves's direction. Left-handed thread grooves are angled to the left. Right-handed threads; grooves are turned to the right.
Left-handed components are often mistaken for accessible products for left-handed individuals. However, left-handed are made to secure a component without becoming loosened over time, which is why they are reverse threaded. This type of thread prevents the element from loosening, caused by the torque of turning parts.
WDS Components offer screws, threads, and bolts in assorted sizes for many uses. Users can identify whether the component is left threaded if the part number has the letter “L”, for example; 552-206L. Another way to find out is by looking at the technical specification table where the column is labelled "Threads: Left”.
