External Wire Terminal Left.

Bolts with left thread.

Extra strong stainless steel bolts for tensioning cable with terminals.

A stainless steel bolt with left-hand thread is a metal bolt made of stainless steel and has a left-hand thread. This means that when you tighten the bolt with a left-hand nut, the bolt turns to the left instead of the right. Stainless steel left-hand threaded bolts are used in situations where standard right-hand threaded bolts are not suitable, for example when tension is put on the bolt while tightening it. Left-hand threaded bolts are also used to prevent the bolt from loosening due to vibration or other movements.
